# Is there a 'Start' button in the bottom left-hand corner of the screen? # Yes - go to 2. * No - go to 6. # Click 'Start'. Is there text down the side of the Start Menu? # If 'Windows server 2003' is written down the side of your Start Menu, your operating system is Windows server 2003. * If 'Windows XP Professional' is written down the side of your Start Menu, your operating system is Windows XP Professional. * If 'Windows XP Home' is written down the side of your Start Menu, your operating system is Windows XP Home. * If 'Windows 2000 Professional' is written down the side of your Start Menu, your operating system is Windows 2000 Professional. * If 'Windows NT Workstation' is written down the side of your Start Menu, your operating system is Windows NT Workstation. * If 'Windows Me' is written down the side of your Start Menu, your operating system is Windows Me. * If 'Windows 98' is written down the side of your Start Menu, your operating system is Windows 98. * If 'Windows 95' is written down the side of your Start Menu, your operating system is Windows 95. * If anything else is listed, that is probably your operating system. * If no operating system information is listed, go to 3. # Is 'Help' or 'Help and Support' listed? # If 'Help and Support' is listed, go to 4. * If 'Help' is listed, or neither is listed, go to 5. # Look at the top right hand corner of the 'Help and Support Center' dialog. Is Windows XP Professional or Home mentioned? # If Windows XP Professional is mentioned, your operating system is Windows XP Professional. * If Windows XP Home is mentioned, your operating system is Windows XP Home. # Close the Start menu. On the Windows desktop, right-click 'My Computer'. Select 'Properties'. #* At the top, under 'System', is a version of Windows mentioned? If so, that is your version of Windows. # Is there an apple logo in the top left-hand corner of the screen? # Yes - go to 7. * No - go to 8. # Is there a tool bar in the middle of the bottom of the screen whose icons expand when you move the cursor over them? # Yes - your operating system is Mac OS X. * No - your operating system is an earlier version of the Macintosh, e.g. OS 8 or OS 9. # Your computer is running some other operating system, or is using a non-default configuration. Check your computer manual, or ask a computer engineer.

Go to account settings and you should be able to change it there. It is the button next to Sign Out that says My Account.

A time shared operating system allows many users to share the computer simultaneously.since each action or command in a time shared system trends to be short,only a little cpu time is needed for each user. As system switches rapidly from one system to next, each user is given the impression that the entire computer system is being used by him,even though it is being shared among many users.

It is useful because in the case where you need to restore data from any storage device no matter what file system they're formatted in, you will be able to retrieve data.

The best OS for playing games is Windows, because most successful commercial games are available for Windows only.

In the Microsoft Windows product family, Windows XP is the best from the point of view of performance, as it consumes less of a computer's resources for itself and leaves more for the game to use and run better/faster.

Windows Vista is more recent, consumes more resources for itself and leaves less for the game, but there are some games that will only run on DirectX 10, which is available for Vista only.

The matter is further complicated however by the fact that some gaming hardware (such as graphics cards, sound cards etc.) have drivers that are not yet fully compatible or bug-free for Vista.

Therefore, for gamers with recently-bought computers (everything inside is new), Vista may be the best. For all other PC owners, Windows Xp is the best.

If you find this confusing, you should probably look into consoles. They are guaranteed to run all games designed for them and do not require such carefully calculated decisions regarding hardware.

Symbian OS is an operating system designed for mobile devices, with associated libraries, user interface, frameworks and reference implementations of common tools, developed by Symbian Ltd. It is a descendant of Psion's EPOC and runs exclusively on ARM processors.

According to Andrew Tannenbaum, the creator of Minix and the author of Operating Systems: Design and Implementation, the two chief tasks of an operating system. The first function is to provide an abstraction layer above the hardware that is easier to program than the bare hardware. By providing this function, the user is freed from the need to worry about interrupts, timers, memory management and other low-level functions. The second function of an operating system is to manager all the various resources of the computer (CPU time slices, RAM, printing etc.) and dole them out wisely among all the various programs competing for them. As an example, let's look at the printer. Imagine if three programs were trying to send output to a printer at the same time. Without an operating system managing the resources, the result would be chaos: a few lines from program 1, a few lines of program 2, a few line from program 3, etc.

1. Microsoft Windows

2. Apple Macintosh

3. Linux (not really a brand since it's free)

some examples are messaging and email

If someone programmed a computer to write everything to the hard drive, then yes it might work but it would be...really...slow and the life span of the hard drive would be significantly decreased. However, if you just took the RAM out of your computer right now, your computer would refuse to work and wouldn't even start up. Compare it to like a person trying to function without short-term memory. We'd have to memorise it, process it, then try and erase it from memory or have it buzzing around in our head for the rest of our life. With RAM/short-term memory, it could just go in one ear, get processed, then go straight out the other ear.

A mobile operating system is an operating system (the most basic instructions to allow a device to load software and control hardware) specifically for mobile devices.

Multi users OS support many users. So many people can utilize the resources of the computer. They generally are multi tasking computers which are faster.

AFAIK there are only 2.

Hardware abstraction and resource sharing.

There are several different PDA operating systems. The most common are PalmOS, Windows CE, and Linux.

Boot block (4K,8L,16K,32K,64K128K) is portion of code in the complete BIOS(1MB5MB). who's responsibility is validate the main BIOS and transferring the control to main BIOS (checks whether BIOS corrupted or not and some other properties).

The microkernel was designed to address the increasing growth of kernels and the difficulties that came with them. In theory, the microkernel design allows for easier management of code due to its division into user space services. This also allows for increased security and stability resulting from the reduced amount of code running in kernel mode. For example, if a networking service crashed due to buffer overflow, only the networking service's memory would be corrupted, leaving the rest of the system still functional.

No, it's just something capable of communicating with something else w/o being physically linked by a wire.

Soft real-time scheduling means that, while processor and other scheduling algorithms may be optimized to give preference to higher-priority processes, no absolute guarantee of performance can be made. The hard real-time computer is designed for specialized purposes, where even the smallest amount of latency can make the difference between life and death.
