Tips on How To Get The Right Kind of Processor For Your Laptops

The desktop computers are considered as an outdated stuff now days. Laptops are considered as the most advanced and reliable option for both professional and personal purposes. It is considered that laptops are more susceptible to the latest technologies. The portability is the yet another reason for its boosted preference. The laptops have overreached the performance of the desktop computers in most of the cases. Still keep your eyes open whenever you go to buy a laptop. You can see so many processor types are available in the market today from single core to dual core.

Most of the laptop processors consume lesser electricity. This keeps the laptop always cool. These processors specially designed to consume lesser power. This is the major reason for the increased life of the laptop battery. This enables you to keep the device on your lap without worrying about the heat that can be produced by the uncontrollable power consumption.

The desktop processors usually consume more electric power than the laptop processors. To avoid the heat due to this power consumption can be eliminated with the help of a built in fan in the computer. Some manufacturers install the desktop processors in the laptop computers for more productivity and to achieve enhanced performance. The disadvantage in this sort of assembling is that it is not at all easy to connect the fan to the laptop and if the fan is installed then it will drain the battery with ease.

Every processor is associated with a cooling solution. The thermal design power is the highest wattage that has to be degenerated by the cooling solution of the processor. To attain a cool processor the lowest thermal design power should be chosen. The productivity and quality of the processor depends on the quantity of the cores in the processor, bus speed and the chip speed. It is the era of next generation dual core.

The cache memory is one the most significant part that decides the processing speed of the processor. The processor is comprised of cores. The processor is the heart of a computer system, whether it is desktop computer or laptop. You should choose a processor carefully since it determines the performance of the entire system.The speed of the computer system extensively depends on the processor performance. If the processor gets slowed down the entire system suffers lack of speed.

The heavy demand of file storage and usage need a high speed RAM. The RAM speed also depends on the processor. Anyway you have to compare different processor models and their performance before fixing a particular processor type. You can even browse the internet for better result. Asking the people who already uses a particular processor can give authentic information on the performance of the processor as well as laptop.

You can find exclusive offers on new laptops, read laptop notebook reviews and compare prices on best selling laptop brands at laptop reviews website.

PCI-Express vs AGP: Which to Choose?

Explains what PCI-Express and AGP is, and looks at the advantages of using PCI-Express.

What is PCI-Express and AGP?

There are two ways to connect a graphics card to a motherboard, either via an AGP or PCI Express slot located on your motherboard. A motherboard only supports one of these slots, so if you're looking for a new video card make sure you're aware of whether your motherboard supports AGP, or PCI-Express.

AGP has been the standard for a long time now, but it is old technology. Its days are almost over, and it's only a matter of time until PCI-Express completely takes over and AGP is left for dead.

Advantages of PCI-Express

The benefit of PCI Express is that it can handle a greater data throughput than an AGP slot. PCI Express offers performance of up to 4 times faster than the fastest AGP slot. It's relatively new technology, and it isn't being used to its full potential yet. Although, we predict that games released in the next 1-2 years will make full use of PCI Express technology.

Another advantage of PCI Express is you can connect more than one video card to your computer for extra performance. This is impossible with AGP, since a motherboard can only ever have one AGP slot.

Should I Buy a PCI-Express or AGP Video Card?

If you're simply upgrading your gaming computer with a new video card, you should check whether your motherboard supports AGP or PCI Express, and then choose a card accordingly. Don't worry if your motherboard has an AGP slot. Even though it's not the latest technology, AGP is going to stay around for a long time. You can still find a great video card with AGP.

On the other hand, if you're building a new system from scratch, you have the choice. We recommend choosing a gaming video card with PCI Express, and a motherboard that supports it. As we said before, the games of the future will soon harness the power of this new technology, leaving AGP in the dark. So by choosing PCI Express now, it will save you the upgrade later when AGP becomes obsolete.

Another thing to keep in mind is not to confuse PCI-Express with its older cousin PCI. A long time ago you would connect your graphics card through a PCI slot on your motherboard. This is very slow compared to today's standards, and is never used anymore.

Hopefully this article has enlightened you about the issues regarding AGP and PCI-Express.

What is Computer RAM (Random Access Memory)

Random Access Memory (RAM) is a form of computer data storage. Nowadays, it has taken a form of integrated circuits that allows the stored data to be accessed randomly.

What is computer RAM? The term random in RAM refers to the fact that any piece of data can be returned in a constant time, irrespective of its physical location and whether it is related to the previous piece of data. RAM helps in accessing any byte of memory without touching preceding bytes. The word RAM is synonymous with the main memory and is reserved for computer related programs.

On the other hand, read-only memory (ROM) refers to computer memory which is used to store programs that boot the computer and perform diagnostics. Most of the computers have a small amount of ROM - around a few thousand bytes.

Random access memory is volatile, i.e. it requires a steady flow of electricity to maintain its contents and as soon as the power goes off, whatever data that was in the RAM is lost. RAM is commonly known as read/write memory and ROM as read-only memory. It is the most common type of memory found in computers and also other devices like printers.

History

During 1949 to 1952, the magnetic core memory was widely used as a writable random access memory. It was subsequently used in most computers, until the development of the static and dynamic integrated RAM circuits in the late 1960s and early 1970s. Before RAM, computers used delay line memory, relays and different kinds of vacuum tube arrangements to implement main memory functions, which were a few hundreds or thousands of bits. Latches built out of vacuum tube triodes and discrete transistors were used for smaller and faster memories such as registers and random access register banks. Before integrated ROM circuits were developed, random access memory was constructed using semiconductor diode matrices which were driven by address decoders.

How does RAM Works?

Like any other memory chip, RAM is made up of millions of transistors and capacitors. A transistor and a capacitor are paired to create a memory cell, which represents a single bit of data. The capacitor holds the bit information as 0 or 1 and the transistor acts as a switch which allows the control circuitry on the memory chip to read the status of the capacitor or change its state. The capacitor is like a small bucket that stores electrons. To store 1 in the memory cell, the bucket is filled with electrons, and to store 0 it is emptied. The problem with the capacitor's bucket is that it leaks and within few milliseconds the full bucket becomes empty. Therefore, either the CPU or the memory controller has to recharge all capacitors holding 1 before they discharge. For this, the memory controller reads the memory and then writes it right back. This refresh operation occurs automatically nearly thousands of times per second.

Types of RAM

There are mainly two basic types of RAM:

• Dynamic RAM (DRAM): DRAM has to be constantly refreshed by the memory controller, as the capacitors that hold the information or data have a built-in leak, which can only be stopped by refreshing the information. This makes DRAM slower and cumbersome.
• Static RAM (SRAM): As compared to DRAM, the storage capacity of SRAM is greater, as it uses on-off switches instead of capacitors. Therefore, SRAM is more expensive, faster and can hold more information.

Both SRAM and DRAM are volatile in nature. Usually, advanced versions of the dynamic RAM are used. These include FPM (fast page mode), ECC (error correcting code), EDO (extended data output) and SDRAM (synchronous dynamic RAM).

Random Access Memory could be considered as an array of boxes, where each box holds a single byte of information. A computer having one megabyte of memory can hold up to one million bytes or characters of information. The speed of RAM is measured in nanoseconds (ns). Lesser the nanoseconds, faster the speed of the computer.

What is Virtual Memory

Virtual memory acts as a supplement to RAM and forms a part of RAM and disk. It gives the computer user a feeling that he has RAM of unlimited capacity while the application program is under the impression that it has an unfragmented working memory.

Virtual memory has become very common for most operating systems of desktop computers available. Computers these days have 64MB or 128MB of RAM space available for CPU operations. Considering the huge demands placed by computer users on the application programs, this space is not sufficient. Also users expect all these programs to run simultaneously which is not possible with the available space. Hence the need for virtual memory.

What is Virtual Memory?
Virtual memory is a technique which tricks an application program into believing that it has a contiguous address space and unlimited working memory. While the fact is the memory may be physically fragmented or extended on to disk storage. Systems that use virtual memory are capable of executing large applications at a fast rate and use real physical memory more efficiently than those without virtual memory. Virtual memory is different from the concept of memory virtualization.

Working of a Virtual Memory
Virtual memory is an intelligent method of utilizing the computer's actual memory capacity and manipulating it using a combination of the operating system and memory hardware capabilities. It acts as a temporary storage medium in which data is stored in a file format. Since the operating system acts as the determinant, it provides quick access to the data and allows smoother operating capacity. Virtual memory works with co-ordination with RAM by storing and presenting data quickly to serve the requirements of an application program. Secondary storage device like hard disk has a large storage capacity but it provides a very slow access to the data.

How Virtual Memory is Organized?
Virtual memory is organized by either paging or segmentation. Most of the systems use page tables to translate the virtual addresses seen by application programs into physical addresses used by the processor to execute instructions. Page table maintains entries for mapping a virtual address to physical address. Systems may have a single page table for the entire system or an individual page table for every application program. Thus paging can be defined as the process of moving inactive virtual memory pages to disk and restoring them to real memory upon request. There are various algorithms to select which pages should be moved to hard disk and which should be retained.

Very few systems use the concept of segmentation for implementing virtual memory. In segmentation memory is divided in variable size segments. Segment number and an offset within the segment together form a virtual address. If a processor wants a particular data item it first looks up for its segment number in a segment table to find a segment descriptor. Segment descriptor gives information whether the offset within the segment is less than the length of the segment and if it isn't an interrupt is generated to notify that the segment is found. If the processor is unable to find the segment in the main memory it generates a hardware interrupt prompting the operating system to swap in the segment. The operating system then searches for the segments that were not in use for a long time and swaps them out of main memory in order to make space for the new segments to be read in.

How to Increase Virtual Memory?
Here is a step by step instruction set to increase the virtual memory of your computer. (For Windows XP):

• Click the menu start, then click control panel
• Select performance and maintenance, under that click system
• Click settings on the advanced tab under performance
• On the advanced tab under virtual memory, click change
• Under rrive [volume label], select the drive that contains the paging file that you wish to change
• Under paging file size for selected drive, click on the check box, custom size
• You can choose the amount of memory you wish to reserve for virtual memory by entering the initial and maximum size
• Click set
• Restart the computer when prompted

If you find your computer running slow then increasing virtual memory won't help, it might be just the result of ' thrashing'. Shuffling blocks of virtual memory between real memory and disks consumes most of computer's time, thus causing thrashing. Though well-designed application programs may help to solve this problem to a certain extent, the ultimate cure is to install more real memory.

If you happen to be an avid gamer and one who spends a number of hours playing high end computer games, then you would certainly be interested in knowing about the type of hardware that best suits your gaming requirements. Of course, if the only PC games that you play happen to be Pinball or Solitaire or Minesweeper, then even an outdated, almost ancient Intel Pentium I processor will do just fine. However, if you're an action 'n' adventure freak who's totally into the likes of Need for Speed, Warcraft, Unreal, Age of Empires, Quake, Grand Theft Auto, etc. then it would be necessary for you to have a high end computer with all the required hardware support. Therefore, on that note, let us have a look at who the candidates are for the coveted title of 'best motherboard for gaming'.

Best Motherboards for Gaming PCs

Before we have a look at some individual computer motherboards, let us first get to know the preferred criteria i.e. the hardware requirements that the best motherboard for gaming should have.

• Processor Compatibility: The CPU is the main workhorse of your computer and the component that is responsible for performing all the processing operations. A gaming PC will typically require a very fast and powerful CPU. At the same time, compatibility of the motherboard with the CPU is something that is extremely important.
• RAM Slots: Gaming PCs have high RAM requirements. The motherboard should have a minimum of 4 RAM slots and should be compatible with DDR2 RAM chips having a speed of approximately 1100 MHz.
• Graphics Card: Video memory or graphics memory is integral to high end computer games which rely heavily on graphics and visuals. Usually, regular motherboards have between 64MB to 128MB of inbuilt i.e. shared video memory. However, most high end games will require you to have a video memory capacity of 256MB to 512MB. In such situations, you would require an additional graphics card which of course, should be compatible with the motherboard.
• PCI Slots and USB Ports:These are also important aspects which play a significant role in high end gaming. The motherboard should have a sufficient number of both and an ideal minimum figure would be 6 for the USB ports and 2 for the PCI slots.

Now that we have established the main criteria for selecting the best motherboard for gaming PC, let us have a look at a few motherboard models which fit the bill. You can also read more on how to choose a motherboard.

Which is Better - AMD or Intel

Planning to get a laptop and confused thinking which is better AMD or Intel? Worry not, read on as the article below will help you with some information on it.

You may get the most fanciest of all laptops, with great features and looks. But then, what really matters is the real machine which lies beneath. And what I am talking about is the processor. Today, the market is flooded with quite a few processors, and amongst them, the most popular are Intel and AMD processors. Both of these just makes the buyer more confused and difficult for one to decide which is better, AMD or Intel. Well, let us find that out.

I still remember a few years back, I had invested a huge amount of money to get my PC, and this was about six or seven years back. It was huge and I had to clear a lot of space in my room to accommodate it. I am sure, if you must have seen them you must be knowing what I am talking about. They had huge monitors and CPU cabinets. Today, they would be hard to find even at the scrap dealer. Nowadays, what we have around is the laptops and notebook PCs. With more and more laptop manufacturers coming up with each unique feature in their respective machines, it really becomes a tough job to choose a laptop in between AMD vs Intel machines.

Which is Better - AMD or Intel Laptops?

Generally, buyers of laptops will always look for two major aspects when deciding to purchase a laptop, and that is the laptop specifications and the price. Most of the times, it is the price which is considered for those who just need a mobile computer. What most of them forget to notice is the small sticker on these laptops which is that of the processor manufacturing company. If you have been out for laptop shopping, you must have noticed that the market out there is dominated by two major CPU makers, and those are Intel and the AMD. Both have their ups and downs.

The major difference between the two is the price. Let's do a comparison between AMD vs Intel processors. So assume that there are two laptops, both having similar specifications and features but with different processors. Now the one with the AMD processor would be less expensive than that which comes with Intel. Though, the market is still dominated by Intel, because of many preferring Intel over AMD. And I could never figure it out, why? Maybe it is because of the marketing and product awareness which they employ. Another major difference in between them is the laptop battery power consumption. Laptop testings have shown that Intel based machines had far much better battery consumption than AMD. It was found out that after getting fully charged, Intel machines ran and lasted 40% more time than AMD. This means that Intel powered machines uses battery power efficiently.

Which is Better - AMD or Intel for Gaming?

For gaming enthusiasts, what matters the most is how big is the graphic card or the video card. It would be interesting to know that AMD produces their processors keeping the ATI graphic cards in mind, whereas Intel makes their laptops to run better with Nvidia graphic cards. Quite surprisingly, it was found that AMD machines had exceptional quality graphics as compared to Intel's.

Hence, if you are a hardcore gamer or like to watch everything in HD, then it is better to bet on an AMD processor laptop. Hence, AMD can be a clear winner between AMD vs Intel for gaming. We cannot neglect the reputation of Intel at the same time for producing some amazing processors time and time again. Again, Intel has lately stormed the market with their phenomenal 'Core i' series, which are truly amazing for their overall performance.

I would say, analyze as per your usage and then decide upon which is better, AMD or Intel. If you want your computer for multimedia use like for gaming, music or video editing, etc., and want a gaming laptop, then I would suggest to get an AMD powered machine. On the other hand, if you don't mind spending more on a computer for its overall performance and the efficient battery consumption, then nothing can be better than Intel. It can be analyzed that, with AMD processors, you are able to get 90% of overall satisfaction with 60% of price. Whereas, with Intel based machines you can get over 98% or more of overall satisfaction with equal percentage of price. The choice is yours! Cheers!

What is Processor Cache

Processor cache is a piece of memory which allows a very high access rate and speeds up computation. It stores the data items that are frequently required by the processor, so that every time there is a demand for that data, the processor does not have to access the main memory.

Main memory is a computer device with the slowest access rate. If the CPU needs a data item, a request is sent to the main memory via a memory bus. The main memory then searches for the data item and sends it back to the CPU. Lot of time is wasted in this entire cycle. What if the data item were stored somewhere close to the CPU? The working of processor cache is based on a similar concept. To understand the concept of cache memory, we will take an example of a library throughout this article.

Suppose, we have a library, with a single librarian. If a person comes and asks for Harry Potter Part I, then the librarian goes to the bookshelf and retrieves the book and gives it to the person. When the person is done with the book, it is restored to the shelf. If, any other person comes and asks for the same book, the cycle is repeated again. This is exactly how a system works without a cache memory.

Why do we need processor cache?

Now, let's see what happens in the presence of a cache memory. In our library example, let's consider a drawer at the librarian's desk as a cache. The procedure remains the same, when the first person places a request for a book. But, when the book is returned, the librarian does not store it on the shelf, instead keeps it in her drawer. Now, when the next person comes and places a request for the same book, the librarian simply has to retrieve it from her drawer. In a similar way, cache memory stores the data items that are frequently required by the processor. Thus, every time, the data is requested, processor simply looks in the cache and retrieves it, saving a long trip to the main memory.

Does cache memory store only the frequently used data items?

No, cache memory is a smart piece of memory that also looks for the data that is likely to be requested in the near future. Continuing with our library example; when the person requests for Harry Potter Part I, our intelligent librarian also fetches Harry Potter Part II along with it. Now, when the person is done with the first book, it is very likely that he might ask for the second part. And when he does, librarian has it ready in her drawer. Similarly, when the cache memory fetches data items from the main memory, it also fetches the items that are located at the addresses near the requested items. These adjacently located chunks of data which are transferred to the cache is called as the cache line.

Two-level processor cache

Most hard drives and other components make use of a single-level cache. But a processor cache is a two-level cache, in which level 1 cache (L1) is smaller and faster; while level 2 cache (L2) is slightly slower, but anytime faster than the main memory. L1 cache is divided into two parts viz., instruction cache and data cache. Instruction cache stores the set of instructions that are required by the CPU for computing; while the data cache stores the values that are required for current execution. L2 cache is responsible for loading the data from the main memory. Again, coming back to our library example, consider a librarian's drawer as L1 cache. On any busy day, when the demand for books is high and the librarian has already stored many books in her drawer, chances are that it might get full pretty quickly. This is where L2 cache comes into the picture. Consider a bookcase near the librarian's desk as L2 cache. When the drawer fills up, the librarian starts storing the books in the bookcase. Now, whenever there is a demand for some popular book, the librarian first looks in her drawer; if the book is not found there, she searches it in the bookcase. Similarly, when L1 cache is full, data is stored in L2 cache. The processor first looks for the data in L1 cache, and if it is not found, then only L2 is searched. If the data is not found in L2 as well, a trip to main memory is inevitable.

Is implementing more cache a good idea?

Yes and no, as implementing more cache will let you fetch data quickly, only in the cases, when the data is available in either L1 or L2. Coming back to our library example. If a person requests a popular book, which is not stored in the librarian's drawer or the bookcase; she first looks for it in the drawer and then in the bookcase. This way, lot of time is wasted before she finally retrieves it from the bookshelf. Similarly, the processor checks first in L1 and then, in L2, and when the item is not found in either cache, then only sends a request to the main memory. As you must have realized, lot of processor time is wasted, in looking for the item in the two cache memories. When the processor finds the required data item in any of the cache memories, 'cache hit' is said to have occurred; on other occasions, a 'cache miss' takes place.

One might think that if cache memory is so fast, why not implement it large enough so as to store entire data of the main memory in it? The reason, is that, although cache memory offers fast access, the speed comes at a great expense. Hence, proper utilization of the available cache memory is must. Data items are periodically updated and replaced using various algorithms.

About Your Android Tablet PC

If you have bought yourself a nice new Android tablet, you will soon find out all sorts of tricks to get the best out of it. Here are a few ideas of what you can expect, and hints that might help you find them even quicker.
You can typically do all of the following on your tablet:

—Most support WiFi.
—You can use Skype, and if you have a built-in webcam you can use Skype to make a video call.
—You can send and receive emails.
—You can browse the web and you can view flash websites.
—You can play YouTube videos and some will play ripped DVDs.
—You can view Pdf files.
—You can view and edit MSWord, PowerPoint, and Excel files.
—There more than 80,000 applications that you can download from Android and a great many of them are free.
—You can increase the storage capacity by inserting a micro SD card, or flash USB device, if your tablet has a USB port. If your tablet has an extra memory slot/socket you can insert another card/stick of RAM to upgrade it.
—If you do your calibration using a stylus, you may find your touch and scroll works more easily. The stylus makes it easier to pinpoint more accurately.
—The screen typically works on a hold down system. Hold down on files and you can cut, rename, etc. Hold down on an empty spot on the screen pane and a menu will appear for you to paste, etc.
—To remove an icon is quite simple. All you do is hold down the icon until a 'bin' appears, then you move it over and hover it over the bin.
—You can use single screen panes or multiple screen panes if you want to load several applications and then scroll between them.

Looking after your battery is probably one of the more important things you can do. Preferably don't let it run completely flat before you recharge. Lithium batteries do not have a memory and their lives are shortened by constantly doing this. Replacement batteries are not always easily available or simple to replace.

Apart from keeping the length of your battery life to the maximum, you will soon appreciate the sheer convenience of keeping your battery fully charged. The very portability of your tablet means that it is essential that your battery lasts and doesn't leave you stranded without power at an awkward time.

Save your battery and make your computer faster by turning off whatever non-essential applications you are not currently using. You may lose a little function, but the advantages usually outweigh the disadvantages. A one-click task killer can help you do this quickly and easily.

Talking about screen brightness, consider not leaving it on the default full brightness, but adjust it to what you need, depending on the environment in which you are working, and no more.
Instead of using 'power off' choose 'hibernate' and save the power your tablet will use for booting up.

The Story of the Android Tablet PC

Pen computing refers to a computer screen that uses the pressure or touch of a pen or stylus instead of the keyboard or mouse or touchpad.

Pen computing technology, surprisingly enough goes way back to the 1800s. An electronic tablet used for handwriting was patented in 1888.

In 1915 a system that analysed handwriting movements was invented.

In 1956 electronic text recognition, without a keyboard was developed. More modern pen computing predates mouse and keyboard technology by at least 20 years.

In the 1980s many companies were beginning to produce tablet type of devices.

At the same time desktop PCs and then laptops were being developed and becoming smaller in size and larger in technological sophistication as they progressed.
In the laptops, portability was greatly improved, but not quite there yet. It would take a tiny tablet with the versatility of use of a computer to be truly and inconspicuously convenient. It could be held in a purse or tiny case and lie on a conference table, no more in the way than a small book.

In 2000, Microsoft produced the Microsoft tablet PC running an enhanced Microsoft Windows operating system.

In 2003, Fingerworks came out with touch technology and this was developed into the interface for Apple iPhone.

In 2005, Google acquired 'Android' a little known cell phone software company. In Nov 2007, it was announced that they were developing a mobile device.
Although on the cards for a while before, Apple caused a sensation with the release of its iPhone, and later, in early 2010 its iPad, with its convenient finger touch interface and the technological world has been in a buzz of excited development, to keep up with, and try and improve on this device.

Because of the limits and restrictions on outside software for use in the Apple iPad operating system, the newer Android operating system is rapidly catching up in popularity. Android offers users the huge advantage of being completely compatible with plugins, downloads and in fact, almost any application available. In addition, there are over 80,000 applications available specifically for Android OS, and a great many of them are available free.

The release of Android 1.1 was announced in February 2009 and its first update, 'Éclair' in December 2009 and January 2010, with improvements, such as Microsoft exchange support. It has a distribution of about 40.4%. 'Cupcake', was brought in, in April. It has an estimated distribution of about 9.7%. With it came Bluetooth support, camcorder video recording and watching, virtual keyboard with text prediction, among other things. In May 2010 came 'Frozen Yogurt' or 'Froyo' together with all kinds of new features, including

Adobe Flash support, Chrome's V8 Javascript engine. Its distribution is 33.4%. The next update in September brought improved technology, including processing speed and camera improvements, and was called 'Donut'. It has a distribution of about 16.4%. On the cards are still 'Gingerbread', 'Honeycomb' and 'Ice cream'. With them are expected a whole host of new features, such as improved copy/paste functions, social networking, support for WebimM video playback, Google TV and many others.

Advantages To Desktops And Laptops

Desktop computers are becoming a thing of the past these days just like cell phones are taking over landlines. Even if you have a desktop; laptops are still very useful things to have. It is sometimes very difficult to get homework done or work done if you are cooped up in a house or apartment. It can be nice to get out to a cafe or coffee shop and change the scenery a little bit. If this is possible, it is a good idea to have a laptop. A lot of restaurants like that even have wireless that you can use. You can buy a used laptop or a refurbished laptop if you cannot afford one full price.

To have a laptop and a desktop is a very good idea because if anything goes wrong with the laptop, you can back your files up to the desktop and vice versa. However, many people travel these days and there is no point in having a computer at their house because they use their laptop for everything anyway. It is so convenient to have something portable that you can have whenever you want that no one cares to even purchase a desktop anymore.

There are however many advantages to having a desktop. First of all, the internet can be much faster when it is plugged in rather than on wireless. They are also much more reliable and there are not as many problems with them because you cannot drop them as easily as a laptop. When things are smaller and portable, they can have things spilt on them or they can be dropped. There is a much greater chance that they get damaged.

Desktops are also much more reliable in the fact that they do not crash as easily as laptops. Since laptops are much newer technology, not all the problems have been sorted out and it seems that there are more internal as well as external problems with the portable computers. They are very handy pieces of equipment to have, but you should always buy the warrantee on them because you never know what might happen. Desktops do not get damaged very easily because they are not being transported everywhere with you.

It is possible to have a stationary computer and a portable one. It actually might be a good idea. You can store your files on the desktop and back it up because it will hold a lot more memory than your laptop and then you can just use your laptop for your current projects and assignments. It is also less of a hassle to use the stationary one while you are at home so that you do not have to get out the charger and worry about the computer running out of battery. There are advantages to both but if you do not want to deal with the desktop if you travel a lot, move a lot, or find it to be a nuisance to upkeep, a laptop will work just find. Just remember to back up your files.

Interesting Things to Use a 3D Scanner On

So, a 3D scanner is used for very serious purposes on a day to day basis, often scanning parts of aeroplanes, jets and sports cars which need to be replaced because of fairly serious crashes or incidents. But, wouldn't it be great if this amazing piece of technology could be used to scanner more comical objects.

A goat
OK so you may be thinking 'why would anyone ever need to scan a goat in 3D' but there could be loads of reasons. For example, there may be a piece of research about the average height of goats or even how quickly they grow from birth to 2 months old!
This kind of data could even be sourced by Veterinary centres or even Universities which teach veterinary courses.

A cactus
There are so many varieties of Cactus out there and so it may be interesting to acquire a 3D scan of each type in order to allow convenient and precise comparisons of each one.
It has been found that certain elements of certain cacti are able to cure illness or help prevent people from becoming ill.

A potato
There are so many things you can do with potatoes, make chips, electrical clocks and even make vodka out of them. So, why not scan them? You never know what could be done with this type of information but it would be great to experiment with growing conditions and then exactly how the potatoes grow in each.
So as you can see 3D scanning machines could be adapted to all sorts of situations, they do not only need to be used for purely mechanical purposed.

Digital Cameras - How Many Megapixels Do You Need?

The more pixels used to represent an image, the closer the result can resemble the original. The number of pixels in an image is sometimes called the resolution, though resolution has a more specific definition. Pixel counts can be expressed as a single number, as in a "three-megapixel" digital camera, which has a nominal three million pixels, or as a pair of numbers, as in a "640 by 480 display", which has 640 pixels from side to side and 480 from top to bottom (as in a VGA display), and therefore has a total number of 640 × 480 = 307,200 pixels or 0.3 megapixels.

When looking at the sales blurb for digital cameras, you will see endless mention of megapixels - and this is indeed a critical feature of your camera. So here we'll explain what they are - and how many you'll need.

A digital camera contains a special device, know as a sensor (sometimes referred to as the CCD), to capture light. This replaces the photographic film used in a traditional camera. The sensor is comprised of numerous tiny 'photosites' that collect light, convert it into an electric form and feed it to the camera's on-board computer. Once the digital information is stored in your camera's memory, it can be reassembled on a computer monitor, on your camera's colour screen, or printer to make your photo. A pixel (from the term 'picture element') is a tiny, discreet location on the sensor that contains the photosite, a micro lens to focus light onto the photosite and other electronics. The number of megapixels refers to how many millions of pixels the sensor in your camera has. A megapixel is the common term for one million pixels, often abbreviated as 'IMP'. A two-million pixel camera will be referred to as 2MP, and so on.

The number of pixels is important because the more a camera has, the more detail it can capture - and the higher its resolution is said to be. Additionally, the more pixels there are, the larger you'll be able to print your pictures. But don't forget, the more megapixels a camera has, the more expensive it will be too.

So how many megapixels should you get when you buy a digital camera? The answer to this depends largely on your budget and what you want to do with your images. You need fewer pixels to post images. You need fewer pixels to post images on the internet and send them as emails, than to print standard 6x4 inch prints. But you'll need more pixels than that if you want to create enlargements. For example, you will get perfectly good 6x4 inch prints from a 2MP digital camera and still be able to enlarge the shot to a print size of around 8x10 inches. With 3MP cameras, you'll be able to enlarge your photos up to a full A4 sheet.

If you buy a digital camera with more than 4MP, then you'll be able to print at sizes up to A3 and even larger. So while a less expensive low-resolution camera might look like a bargain at first, if you want to create large prints then it's not the camera for you. Happily, all digital cameras can be set up to use less than their full complement of pixels, so you can tailor shots to their end use, such as the lesser number of pixels needed on an image to be emailed. This is even true with a very high-resolution model.

Another thing to remember is that the more pixels your camera has, the more memory the shots will use up - per photo - because each image will then be made up from more pixels and so contain more digital information.

Thank you for reviewing this article, I hope you found the content useful and of great help.

Tips for Users to Protect Their Devices From Email Threats

Recently, when the "Here You Have" virus did its rounds and created panic among some of the major corporations - Google, ABC, Disney, etc., I was forced to think what can we, as users, do to ensure that we are least affected.

2011 is coming. Email is part of our daily life and so are the mobile devices like iPhones and Androids. An average user today has at least two devices where he maintains his data. Spam blockers and security policies have always been installed by security administrators to ensure that the corporate space is impervious to attacks. But the truth is that email moves faster than IT folks modifying the policies to stop attacks. We users need to be more responsible, proactive and smart to ensure that the data on our devices is safe, secure and invulnerable to malevolent agents.

Below are some simple steps any user can easily adopt to secure his personal and corporate data on all mobile and non-mobile devices.

1. Pay attention to the email while reading. Do you recognize the email sender? This could be fake and it almost always is fake when the email is spam or a virus, so this is not foolproof, but at least it gets you thinking. If you don't recognize the person sending the email at all, you shouldn't follow instructions within the email. In short, keep an eye out for any fake or spam email IDs.
2. Were you expecting this person to send you a document (or attachment)? Does this person typically send you items via email? If you have doubts, pick up the phone and say "Hi."
3. Read the subject and body of the email. Does it make sense? Poorly worded email messages or déjà vu subject lines are a flashing red light indicating that something is wrong. For example, in the case of the "Here You Have" virus, the subject was pretty vague (it actually talks about sex movies).
4. Don't open attachments or click on links that you weren't expecting to get. If you weren't expecting it, don't open it. Before downloading the attachment to your hard drive, do a virus scan.
5. Before clicking on a link, put your mouse over the link. It should display the actual URL the link will take you to. Does it match what's displayed? Do you recognize the URL? This can sometimes be a little tricky, but could save a lot of headaches down the road.
6. Do not forward any suspicious email. If it does contain, or point to, a virus, you're simply helping to spread it. Also, don't reply to the email asking if it's them, since it may not actually go to that person if it's spam.
7. Avoid sending your personal information or filling out forms in an email.

So next time you hear about a Virus, Worm or Trojan visiting your neighborhood, don't flinch! Do your bit!

Best Tech Gears of 2010

The year about to end has seen some of the most exciting gadgets sporting unmatched technical wizardry since the start of the 21st century. Here are some of the most noteworthy that should be part of every technology geek's collection before the year ends, in no particular order

- 3D home viewing have started to make waves after two years of high definition Blu-ray has emerged as the new home theater standard. The first 3D televisions hit store shelves late last and new models with stunning features from, consumers electronic giants like Panasonic, Sony and Samsung are scrambling to lead what is to become the viewing phenomena of the next decade. Still nascent, 3D content is starting to grow with blockbuster Hollywood titles filmed in 3D like Cameron's Avatar but the more important thing is that the video players and monitors are geared up for them. There is no clear winner but it's safe to say that both
Samsung with its 55-inch LED 3D TV (UN55C8000) and the Panasonic 58" 3D Plasma (TC-P58VT25) lead the pack. Expensive for now but expect this home theater tech gear to come don in price in the next couple of years.

- The iPhone created a landmark sensation in 2007 and it gets repeated this year with its 4th generation iPhone 4. With its retina display boasting the highest resolution and dot pitch that has no equal, the first with a 4-point gyroscopic motion sensor, the new iPhone 4 pushes the envelope on smartphone gadget wizardry like it did with the multitouch capacitive display of its first iconic launch. Never mind that at 9.3mm, it remains the world's thinnest smartphone todate.

- Gesture and motion sensing game consoles pioneered by Nintendo's Wii got enhanced early this year but it was bettered by Microsoft's new generation Xbox 360. The new generation Xbox can be equipped with an optional Kinect that allows you to control games by gesture. Console gaming tech gears never had it as good.

- Tablet computing has been around since the 90s but never caught on with consumers until this year. Thanks to multimedia-centricity and multitouch displays, you have the like of Apple iPad, the Samsung Galaxy Tab and the Archos 7 taking consumer tech gears by storm. Needless to say, the iPad reigns supreme in this market niche.

As far as tech gears go, the digital camera sits at the top and the point-and-shoot cameras remain perched there among the most crowded of all consumer gadgets. You now have 10 - 12 megapixel resolution cameras with 10x optical zoom with a slow motion video as standard offering with adjustment features that make them no less feature rich as professional digital SLRs. Canon and Casio lead the pack such as the Casio Exilim FC100 with a 1,000 fps shooting speed for ultra fast capture that can leave you breathless.

Computers and Notebooks

Computers and notebooks are among the most expensive purchases you can make. Why is it then, that so many make an uninformed decision when it comes to their technological needs? It may be because they what they think is a good deal and snatch it up before the sale ends or the item is sold out. Others may just need a new computer quickly to replace one that dies. When shopping for a new computer, you want to make sure you make a good decision that will last you at least a few years. One of the most important considerations will be whether you want a desktop or laptop computer.

Before you decide which type of computer you want, you should think about your needs regarding the item. Computers and notebooks can each be purchased with the same specifications, so you will not have to decide on one type just to get the things you need on the inside. Determine the size of hard drive and RAM you need. Think about the audio and video quality you want the computer to have. Do you need extras such as additional USB ports or webcam? These are all things to think about when buying a computer.

Once you have determined what you need, you begin looking at desktop or laptop computers. The main reason for choosing between the two is primarily your needs for portability. If you travel a good deal and need your computer with you, it is best to go with a laptop. However, if you are simply looking for something to keep on at home, a desktop computer may be a better choice for you. If you decide to go with a laptop, there are additional considerations, such as battery life and weight of the computer that should also be made.
Budget is another factor that should be considered when you are shopping for computers and notebooks.

Computers have become a bit more affordable nowadays, but if you want a top of the line brand or model, you should expect to pay top dollar. Desktops tend to be cheaper than laptops, but that is probably because of the ability to carry laptop computers with you where ever you go. No matter which type you choose, there are a number of models that can be purchased for less than $1000.

As you can see, there are a few considerations that you should make before you start to shop for computers and notebooks. With the price of the item, you will want to make a well-informed decision so that the computer will last you several years. Think about the specifications you need, as well as whether you want to buy a desktop or laptop. Also, set a budget so that you do not break the bank when making your computer investment.

The Essential Computer Buying Guide

Buying a computer is a big investment of time and money. Computers have increased our society's efficiency in the market place, as well as for personal uses. But what happens when that big investment of time and money starts showing signs of trouble - and then kablam! Your computer craps out on you and you are left stranded on the phone waiting in line for 15 minutes to talk to someone who didn't sell you your computer and is having trouble explaining the technical problems your computer is having and how YOU can fix it. Investing five minutes in reading this articulately written article could save you hours of frustration and pain in dealing with BAD customer service and computer products.

The Essentials
There are some essential things that the typical consumer should know and research before buying a computer. Throughout this article you will learn about quickly researching computer companies, what warranties should cover, tech support and customer service, reliable name brand parts, and buying on budget and lifestyle. After you have read this article you will feel good about your next computer purchase.

Warranties
When reading a warranty, there are key points which every consumer should look for. These include: What is covered, what is not covered, how long the coverage lasts, what will the company do (ex: repair or replace parts), how to get serviced (who will you talk to?), and your rights as a consumer under state law. Make sure to look for these as they are very important, and if you have any questions make sure to ask them. Don't buy from anyone who seems shifty or not willing to talk about the warranty of their products.

Technical Support
Technical support and customer service is very important to most people because nobody likes getting the run-around telephone tag game. Unfortunately, the most computer companies have decided to outsource their customer service and tech support, as well as making their customer's wait in queue listening to drab music until they can be helped. Find a company (preferably a local one) that can guarantee you immediate customer support from a technician who is trained in customer satisfaction.

Choosing the right brand name parts
If you're looking to have your computer last you a while, you want to make sure that your computer is equipped with name brand parts. Popular names such as Intel and AMD (processors), ATX (motherboards), Seagate (hard drives), and Nvidia (graphic cards) are some examples of trusted quality name brand parts. The age old adage "you get what you pay for" is true when it comes to the computer industry. Cheaper parts usually means a shorter life span for the computer.

Tips for Buying a Computer

When buying a computer there are many different things that you will need to look for. In addition to considering your needs you will also need to consider your budget. This obviously will affect the type of computer that you can purchase. We all want as much as possible for very little money but where a computer is concerned you really do get what you pay for. You have to think about what you want to use the computer

for as this will determine some major factors.
Although very powerful computers are being sold a lot, and you are often told that these are the ones that you have to buy, they can be expensive. Even if you spend the money and get a very powerful computer you have to decide if you are really going to use the machine to its maximum potential. If you only want to use your computer for very basic things, then you would be better off saving your money and buying a lesser computer; one that would suit you needs better.

Basic computers are great for teenagers or for very basic work, but if you want to do anything more advanced, then you will need something more substantial. If you can afford it then it is well worth spending a bit more and getting a machine that will allow you to do other things. You can also upgrade these machines to a higher specification if you want them faster or with more memory. A larger amount of memory will allow one to work faster and do more tasks at once.

If you want to spend a lot of time on your computer either surfing the Web or playing games, then you will need one that has a lot of memory. You will be amazed at the specifications that you can get on your computer and if you can afford them then they are well worth it. If you think that you will need a faster computer then you should look at top range computers. You can find computers in stores and online. It is important to do your "homework".

You do of course have to like the look of the computer as it will be on your desk. You need to think about where you plan to place the computer and the location of the USB ports as you will need to be plugging and unplugging things. You should research the different computers available and then decide which one will fit your needs and budget. Researching well can save you time and money when buying a computer.
