Windows 7 – Future of Operating System

Windows 7, the latest operating system by Microsoft is similar to Microsoft Vista but not the same .

Windows 7, the upcoming and latest version of Microsoft Windows is the successor of the famous Windows Vista Operating system. It is an incremental upgrade to the Windows line of operating system that aims at being compatible with all the hardware and software applications with which its predecessor is compatible. Some interesting features of Windows 7 include a touch screen functionality, a completely new task-bar, larger thumbnail previews, Internet Explorer 8, a home networking system that is known as HomeGroup and of course enhanced performance. This operating system was initially slated for a January 2010 release, which has now been postponed for the holiday season of 2009.

Looking at the features and functionalities, the Windows 7 appears to be similar to Windows Vista, however it is not so. With the Windows 7, you will be able to defragment multiple hard drives at the same time, create a sandboxed user account for children so that they are unable to mess with the Windows and programme settings. In fact with this operating system, you can encrypt the USB flash drives to protect the data and files. Also, a number of tools have been provided for fine-tuning the display settings for crisp colors and clear text.

System Requirements

Microsoft is reported to claim that the recommended specifications for a system to have Windows 7 is same as that for Windows Vista Premium version. A bets version of the upgrade advisor can be used to scan the computer and check if it is compatible with the new Windows 7 operating system. The system requirements include a processor clocked at 1GHz, 1GB of RAM and 16 GB of available disk space.

Security Functionalities of Windows 7

Today every person has loads of important files and data stored on their laptops or desktops. In case someone else who is less experienced with computers uses your system, then there are chances of mess-ups happening. In case of Windows 7, the changes made by a guest account is completely reversed, as in the files saved by them are deleted and the changes made to the system's settings are also annulled. This can be done by enabling the PC Safeguard option in the guest account. The guest account which has this function disabled will be able to make changes entitled by the administrator to the guest user. You can even lock or control your applications by using AppLocker. It restricts the users to just the applications specified by you, providing you with more control. Windows Security Centre application has been replaced by another application known as Action Centre. This Action Centre alerts you about the maintenance of the computer, issues with back-ups and also some kind of potential security problems.

User Account Management

With the Windows 7 operating system installed on your computer fewer warnings and alerts are supplied as well as more useful User Account Control tweaks are offered. For safeguarding the USB flash drive, you can activate BitLocker feature provided by this operating system. Windows 7 has included all the troubleshooting applications into one single "Find and Fix Problems" applet, which is situated in the Control Panel. This applet checks for all kinds of incorrect settings and repairs it.

Trouble-Shooting Assistance

If an application is acting weird and not functioning properly in the Windows 7 operating system, then the user just needs to start the "Problem Steps Recorder" application and hit the record tab. It will make note of the step by step process for completing the task. Windows 7 is offering a Resource Monitor in place of Task Manager that displays full detail of the number of processes currently running in the system along with particulars about the how they are utilising the RAM, CPU, network and hard drive. Additionally the Windows 7 operating system has introduced many new shortcut keys for user friendly operation.

Verdict

Overall, the Windows 7 operating system can create a productive and efficient work environment, provide better security and data protection whilst offering easy to use user friendly functionalities.

Different Types of Operating Systems

Operating systems that create a link between users and the applications form the core of computer systems. It dissociates the programs and the hardware and simplifies resource management. Let us look at the different types of operating systems.

An operating system is a software component of a computer system that is responsible for the management of various activities of the computer and the sharing of computer resources. It hosts the several applications that run on a computer and handles the operations of computer hardware. Users and application programs access the services offered by the operating systems, by means of system calls and application programming interfaces. Users interact with operating systems through Command Line Interfaces (CLIs) or Graphical User Interfaces known as GUIs. In short, operating system enables user interaction with computer systems by acting as an interface between users or application programs and the computer hardware. Here is an overview of the different types of operating systems.

Real-time Operating System: It is a multitasking operating system that aims at executing real-time applications. Real-time operating systems often use specialized scheduling algorithms so that they can achieve a deterministic nature of behavior. The main object of real-time operating systems is their quick and predictable response to events. They either have an event-driven or a time-sharing design. An event-driven system switches between tasks based of their priorities while time-sharing operating systems switch tasks based on clock interrupts.

Multi-user and Single-user Operating Systems: The operating systems of this type allow a multiple users to access a computer system concurrently. Time-sharing system can be classified as multi-user systems as they enable a multiple user access to a computer through the sharing of time. Single-user operating systems, as opposed to a multi-user operating system, are usable by a single user at a time. Being able to have multiple accounts on a Windows operating system does not make it a multi-user system. Rather, only the network administrator is the real user. But for a Unix-like operating system, it is possible for two users to login at a time and this capability of the OS makes it a multi-user operating system.

Multi-tasking and Single-tasking Operating Systems: When a single program is allowed to run at a time, the system is grouped under a single-tasking system, while in case the operating system allows the execution of multiple tasks at one time, it is classified as a multi-tasking operating system. Multi-tasking can be of two types namely, pre-emptive or co-operative. In pre-emptive multitasking, the operating system slices the CPU time and dedicates one slot to each of the programs. Unix-like operating systems such as Solaris and Linux support pre-emptive multitasking. Cooperative multitasking is achieved by relying on each process to give time to the other processes in a defined manner. MS Windows prior to Windows 95 used to support cooperative multitasking.

Distributed Operating System: An operating system that manages a group of independent computers and makes them appear to be a single computer is known as a distributed operating system. The development of networked computers that could be linked and communicate with each other, gave rise to distributed computing. Distributed computations are carried out on more than one machine. When computers in a group work in cooperation, they make a distributed system.

Embedded System: The operating systems designed for being used in embedded computer systems are known as embedded operating systems. They are designed to operate on small machines like PDAs with less autonomy. They are able to operate with a limited number of resources. They are very compact and extremely efficient by design. Windows CE, FreeBSD and Minix 3 are some examples of embedded operating systems.

The operating systems thus contribute to the simplification of the human interaction with the computer hardware. They are responsible for linking application programs with the hardware, thus achieving an easy user access to the computers.

Why to Create a Recovery Disk?

Which are the main advantages to create a boot restore disk? Save your time by preparing an image of your operating system for emergency situations.

A Restore Disk is no doubt among the necessary tools that you simply will need to have if you a poses computer. If you buy a computer from your store it comes pre-installed with an Operating System, usually Windows. It comes accompanied which includes a Boot Disk which enables you to recover your original Windows OS in case of a failure.

Operating Systems like Windows become very slow in time. Just the usage of this system like {net surfing|internet browsing|, can damage your registries by allowing to certain websites to install specific content, plug-ins and software. If they are not present you can’t do your job, so that you don’t possess a choice. There are so much of software programs these days that you must install on a newly installed Windows to benefit from it, no speaking of device drivers, windows updates and patches, that a full installation of Windows up to date can take a long time, a minimum a couple of hours. To not mention specific settings and profile information used everyday.

That’s why you should have a back-up solution, a sort of back-up of the Operating System. This can save you lot of your time needed by a fresh install of Windows|This will save your efforts and energy of a new Windows installation}. You can have all your data and all your settings back in several minutes updated at the time when you decided to create a copy of the Windows partition. You don’t need special computer skills for this procedure. Another benefit is that it can be realized on all Windows distributions (95, 96, 2000, XP, 2003, Vista, NT).

There are special accessories for this operation like Norton Ghost or Acronis True Image. They may be both simple, fast, effective and no cost. What they do ? They create a copy of your desired partition, in our case C:\ partition (if we presume the Windows installation is on C:\). This is an image file with all the files contained on that system partition: windows file system, profile files, device drivers and installed software. All files are copied on that ghost image. So, a recommendation prior to make this recovery disk would be to proper install Windows with all its drivers, service packs if it’s the case, network configuration, software that you simply use and personal user configuration. Just before you make a clone of the Operating System I advise you to make use of the computer for a while, until you possess the full installation and configuration you need day by day. At that time just install Norton Ghost or Acronis. Follow the steps (they have help menu) for creating a boot floppy disk or CD/DVD. Boot from them and do the copy of your Windows partition to an image to a different disk partition. Reboot Windows from hard disk and save that image in a DVDor somewhere safe.

In time when your Windows OS will have errors, it will be slow, having problems on boot or even just fail to boot, you simply boot with the floppy/CD Norton Ghost created disk and you choose to restore your previously created image for the OS which contains the Windows operating system itself.

Linux vs. Windows

Operating system or OS is system software that manages and controls the computer resources and gives users with an interface used to access these resources. OS can be found for almost every device that is made with ICs like PC, Internet Servers, portable music players, cell phones, digital cameras and video games. There are five most popular computer operating systems including Windows, Linux, UNIX, Mac and Novell. Among these Windows and Linux are the most widely used and most popular operating systems.

But both these operating systems, Windows and Linux, are completely different in technology, interface and reliability. The main differences between Windows and Linux are as follows:

1. Linux is an open source operating system whereas Windows is a closed source operating system. You can reproduce and copy the Linux codes at very low cost but not of windows.

2. Windows is very costly as compared to Linux. Linux is completely free operating system. But both these operating systems are very expensive to maintain.

3. Linux is more reliable operating system as compared to Windows. Windows creates several hidden problems that can lead to system failure. Time pressure for development of the publicized closed source product to fulfill a sales target is also a thought to play a big role in the number of errors.

Reliability is the major problem with windows operating system. It causes hidden errors that can lead to system failure and ultimately can cause data loss.

Data loss is one of the biggest problems for computer users where he/she losses all of the important data stored on computer that can lead their business to destroy. In these situations, it becomes very important to recover these data.

You can recover your lost data with the help of software. Data recovery software can be different for different operating systems. For Windows operating system, these software are known as windows data recovery software. These are the hard drive data recovery software that can help you in recovering all of your lost data from computer hard drive no matter what is the reason of data loss.

Stellar Phoenix Windows Data Recovery is robust and powerful data recovery software that you can use in all possible cases of data loss from windows computer. This data recovery software uses advanced scanning algorithms to search and locate the lost data and recover them in the original format. This software also works as Partition recovery software and can recover the lost or missing windows hard drive partitions based on FAT and NTFS file system.

Stellar Phoenix Windows data recovery software is compatible with all file versions of Microsoft Windows including Windows 98, 2000, XP, 2003 and Vista.

Notebook vs Laptop

Not quite aware of the difference between notebooks and laptops prompts many people to use these terms interchangeably for any portable computer. Notebook vs laptop comparison given below will help you in understanding the difference between the two, in order to choose the ideal one for you.

As we cruise along the highway of technology, leaving behind one milestone after another, our gadgets are becoming smaller and smaller. Introduction of laptops and notebooks - the improvised versions of the traditional desktop computers, is by far the best example of this phenomenon. Though there is quite a significant difference between notebooks and laptops, many people tend to get confused when it comes to differentiating between the two. In such circumstances, we need to we need to find out more information about each of these, before we move on to notebook vs laptop comparison to find out which is ideal one.

Laptop
The term 'laptop' is used to refer to a small portable computer, which is almost as good as the desktop PC in terms of performance, but runs on battery, and hence has a shorter life. Their small size means you can carry them along with ease. In fact, the name laptop is derived from the fact that it is so small that you can easily place it on your lap when working on it. Being compact in nature, laptop computers are relatively expensive compared to desktop computers. Read more on best laptop deals.

Notebook
The term 'notebook' on the other hand refers to a portable computer, even smaller than the laptop in terms of size, but having a greater battery life compared to it. They are also referred to as notebook PCs owing to the fact that they are as small as actual notebooks. Being small acts as an advantage for notebooks as they can be conveniently carried along anywhere. Notebook computers are relatively cheaper than laptops, as they have lesser features compared to the later. Read more on best notebook computers.

Notebook vs. Laptop
In terms of size, notebooks have an edge over laptops owing to the fact that they are much more smaller than the later, and hence can be easily carried along. Even though you can carry laptops along, when it comes to convenience notebooks do score some extra points over their counterparts. The cooling system in laptops, which is adjusted to fit into the smaller case of the laptop, is similar to the cooling system in desktop computers to a significant extent. In notebook PCs, however, the cooling system is not at par with that of laptops or desktops. Notebooks being small and having relatively less components require less power to operate than what laptops require. The battery life of a laptop ranges between 2-3 hours depending on your usage, while the same in notebook ranges between 4-6 hours.

When it comes to processing, laptops again have an edge over notebooks. Laptops are much more compatible to hardware change than notebooks. Hardware replacement in notebooks is most often bound by manufacturers compatibilities, while laptops are compatible to a range of hardware owing to their bigger size. More importantly, various drives are integrated into a laptop in most of the cases, which is not the case in notebooks, wherein you do have the option of attaching these drives externally, but that is not as convenient as integrated system. Though some notebooks available today do give a range of facilities almost like the laptop, they compromise on size owing to which the notebook loses its 'notebook' feel.

Which is Better: Notebook or Laptop
At the end of the day, the compact size of notebooks acts as a boon as well as curse for them. Being small in size means you can easily carry them around, much more conveniently than you can carry laptops, but than the small size also means you have to compromise on several features which laptops and desktop PCs offer. In such a scenario, you should make a list of the features that you need in you computer, and depending on it opt for a laptop or a notebook. If it is size or mobility for you notebooks are fine, but if faster processor and more storage is what you vie for then you should go for laptops. Read more on computer buying.

Over the period of time, notebook vs laptop comparison has lost its value owing to the fact that both of them come with almost similar features today. The laptop may have an edge over the notebook, but that is negligible. It wouldn't be surprising to come across sources which stress on the fact that notebooks and laptops are one and the same thing, and using the terms interchangeably is perfectly normal.

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.
