This stores the data which tells the computer how to load the operating system when it is switched off or rebooted?

ROM
ROM is an acronym for Read Only Memory. The advantage of ROM is that its contents do not evaporate when the power is switched off. Therefore the program which needs to execute when the computer is first switched on is stored in a ROM chip on the computer's motherboard.
Once the program stored in the ROM chip has finished initialising the hardware, it moves the head of the hard disk to track 0, reads the first sector of track 0 into memory, and then passes control to the short program stored in the first sector of the hard disk. To simplify a bit, it is the responsibility of that program to locate the operating system files on disk, and then begin the process of loading them.

What part of the computer that stores all programs and operating system?
I am assuming you're asking what part of the computer sotres data in general. Well that would be the computers hard drive. To learn more about hard drives, go to www.howstuffworks.com and search "hard drives".
Differentiate between desktop operating system and network operating system?
Assuming you're like the 99% who are using PCs or MACs: An operating system resides on your local computer and it's function is to allow the software to work with the hardware on that machine. A network operating system allows multiple computers to connect to each other, controlling the sharing of devices, files or programs. This resides on a shared computer called a "server". The computer then stores data on the server-side and not the client-side making it faster and more efficient. Instead of running a hundred computers with a full computer that it doesn't use all the resources and replace them with thin clients and gigibit network would make your network infrastructure 10x faster.
What part of operating system stores utilities or frequently accessed function?

What stores the data which tells the computer how to load the operating system when it is switched on or rebooted?
A computer boots up by first running a program in Read Only Memory (ROM) that is built into the computer's motherboard. This program is called the Power-On Self Test (POST) and Basic Input/Output System (BIOS). After checking the hardware, the program consults a nonvolatile parameter memory (called "PRAM" or "CMOS" for historical reasons) that acts like Flash memory in that it can be changed but retains its information without power. From this parameter memory, the program in ROM decides where to look for the next step.Typically the next step is to read the first block ("boot block") off of the first hard drive into memory and run the program in it. Other options are to read the first block off the floppy, the CD-ROM, or from the network.In the hard drive situation, the program in the boot block figures out which disk partition is the active partition, loads the boot block from that partition into memory, and runs that program. This allows you to have different operating systems on different partitions and choose which one to run by changing active partitions.The second boot block program loads a more elaborate loader program from the disk, which in turn loads the operating system (finally!).Most PCs have a "BIOS screen" that you can get to by a key sequence (F1 or ESC) during the boot process. This BIOS screen allows you to change the nonvolatile parameter memory; however, it is possible to make changes that will keep your computer from booting, so be careful. For example, bad values in "RAM Timings" will cause serious problems.
Where are none essential parts of operating systems stored?
You mean "Where are the essential parts of operating systems stored?"Depends which operating system. Linux stores stuff in a few different places, as does Unix. Windows stores itself inwhich is by default C:\WINDOWS where C is the drive letter of the primary drive.Maybe they meant, "non-essential?" The answer is still C:\WINDOWS as far as I know for Microsoft OS's.
What stores data on a computer when it is switched on or rebooted?
If you store something on the computer you would put it on a usb port.
What is the primary advantage in file?
It stores data, even when the computer is switched off.
Is a hard drive a processor?
Yes it is, it is built into the computer and stores operating systems, programmes and data.
What is the unit storage generally used for ram?
The unit storage generally used for RAM is bytes, megabytes which is MB, and gigabytes which is GB. 1 gigabyte is equal to 1024 gigabytes.
What does the computer disk do?
The computer's hard disk stores data - be that the operating system, application programs, documents or virtual memory.Stores data that needs to be kept between times when the computer is turned off.

When you turn off the computer data stores where?
When your computer is shut down, the data is stored on your hard disc drive. RAM stores the operating system while the computer is running. Hard discs are non-volatile, so it will always be there. However RAM is volatile, and once you do not supply power to it, all memory is lost.
What role does a hard drive plays on the computer?
The hard drive stores the Operating System. Like for example : Windows XP or Windows Vista or even Windows 7 without the hard drive your computer will not turn on.
What stores do you get laptops in?
