Both. The software resides in the nonvolatile memory when it is not being run, and a copy is loaded into main memory when it is being run. Programs have to reside in RAM in order for the CPU to process their instructions.

How can the processor find data items stored in main memory?
The software would tell it where to find the items.
Where The information stored in RAM is erased when the computer is turned off?
Main computer memory is called volatile memory. It holds data only as long as it is provided power. When you turn off the computer, you remove power from the memory chips and they loose the ability to hold data. If you want to keep your information, ensure you save it to the computer hard drive before you switch off the computer.
Distinguish between in primary and secondary memory?
Primary memory, also known as main memory, refers to the computer's directly accessible memory that includes RAM and cache memory. It is volatile and stores data that is actively used by the computer. Secondary memory, on the other hand, is non-volatile memory that includes storage devices like hard drives and SSDs. Data stored in secondary memory is retained even when the computer is turned off.
What is volatile and why are using in java?
volatile variable is mainly used in multithreading environment. so let me explain it from that context.In a multithreading environment,for a variable which is not marked as volatile will be stored in local cache memory for each thread. Meaning each thread will have a local copy of the variable and they dont know about what value this variable is having in another thread. If a variable is marked volatile, then the updations to this variable will happen in the main memory and not in local cache
What can be stored in the main memory of a computer system?
Computer memory
Is BIOS volatile or non volatile?
BIOS is a program (stored in ROM), not a memory.However the BIOS uses a battery backed up RAM to store a variety of settings and parameters. This BIOS RAM is itself volatile (it can only store data when powered), however the battery backup provides power to this RAM when the main power of the computer is off (making it act as if it were nonvolatile). When this battery dies the BIOS RAM will lose its data and (after the battery is replaced) the machine may have to be reconfigured from scratch before the machine will startup correctly.
Which of the following terms is the most closely related to main memory?
non volatile ROM
Global variables are stored in?
Main memory (RAM).
Which system software resides in main memory?
LOADERS
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.
Difference between main memory and backing storage?
Main memory (RAM) is fast, volatile, and used for temporary storage during program execution, while backing storage (like hard drives or SSDs) is slower, non-volatile, and used for long-term storage of data.
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..
