Where is the operating system stored in the computer for quick access by microprocessor?
in main memory
Where is the operating system located in the computer?
The operator system is software- a program that controls the computer. It is usually stored on the hard drive when the computer is not running and is read into a special portion of main memory when the computer is booted up. (There is a boot strap program stored on a chip that loads the O. S. into memory. ) Some of the routines needed by the operating system are not kept in the main memory but are read in only as they are needed.
Where is the operating system stored before it is loaded into main memory?
on the hard drive
What is optical memory?
Optical memory is an early form of computer memory. It involves the use of an optical system for the writing and reading of data to and from a computer's main memory.
Where the variables are stored in the computer?
Variable stored in the memory block inside the RAM. whenever we declare a variable it would take space in main memory and consume it's size from RAM.
What is a memory and its types?
Virtual memory Main article: virtual memory Virtual memory is a system where all physical memory is controlled by the operating system. When a program needs memory, it requests it from the operating system. The operating system then decides what physical location to place the memory in. This offers several advantages. Computer programmers no longer need to worry about where the memory is physically stored or whether the user's computer will have enough memory. It also allows multiple types of memory to be used. For example, some memory can be stored in physical RAM chips while other memory is stored on a hard drive. This drastically increases the amount of memory available to programs. The operating system will place actively used memory in physical RAM, which is much faster than hard disks. When the amount of RAM is not sufficient to run all the current programs, it can result in a situation where the computer spends more time moving memory from RAM to disk and back than it does accomplishing tasks; this is known as thrashing. Virtual memory systems usually include protected memory, but this is not always the case.
What do you understand by a memory of computer system?
Memory of computer system is the part of the computer's hardware that allows it to store information. It is classified into primary/main memory (RAM and ROM) and secondary storage (hard drives, CD drives etc.).
Can you use ddr2 ram on your computer with a gpu that uses gddr3 memory?
Yes. The type of video memory has nothing to do with main system memory.
What is a cache?
Answer:- The Cache memory is placed between the CPU and the main memory. It is a fast speed memory and is expensive and faster than the main memory. Cache memory is used to store the frequently accessed data of main memory. The instructions that are frequently used by the CPU are stored in the cache memory. It is used to reduce the average access time for address, instructions or data, which are normally stored in the main memory. Cache memory increases the operating speed of the system. But is much costlier than main memory. From economic considerations, the capacity of the cache memory is much less as compared to main memory..
Is cache memory is the main memory of cmputer system?
NO...The cache is a smaller, faster memory which stores copies of the data from the most frequently used main memory locations. As long as most memory accesses are cached memory locations, the average latency of memory accesses will be closer to the cache latency than to the latency of main memory.Thus Cache memory is not main memory of computer system.--- form Wiki
What are the functions of system memory?
the main role of memory is to let OS copy in it.. means when we start PC, 1st OS gets copied on ram.. it also important for software or program..
Global variables are stored in?
Main memory (RAM).
