Random Access Memory(RAM for short) , or volatile memory, is used by the system to store data for processing by a computer's central processing unit (CPU), also known as the processor. RAM stores the data in memory cells that are arranged in grids much like the cells are arranged in a spreadsheet, from which data, in the binary form of 1's and 0's, can be accessed and transferred at random to the processor for processing by the system's software.
The data stored in a hard disk drive (HDD) cannot be accessed at random. Whole sectors, containing blocks of data, are transferred from a hard disk drive, placed in a large swap file on the same drive, and only then are selected files transferred to RAM for random access by the processor, which is itself only performing the instructions of the system's operating system (usually Windows), and its application software.
Whenthe computer is turned off, all of the data in the RAM memory is lost, hence its alternative name of volatile memory, whereas all of the data on a hard disk drive is retained permanently until it is intentionally erased. The motherboard (or mainboard) manual (that should be provided with a new or a second-hand PC) will provide all of the details about the different types of supported RAM, and the various combinations of modules per bank for each type that can be successfully installed.

Distinguish between primary memory and auxiliary memory?
the main memory is the central storage unit of the computer system. it is relatively large and fast memory used 2 store the programs and data during the computer operation.main memory communicates directly with the CPU. main memory includes RAM and ROMs. devices that provide backup storage are known as auxillary memory. auxillary memory are relatively slow in comparision to the main memory. auxillary memory includes flash memory,magntic disks and floppys. main memory is located inside the CPU but auxillary memory is located out the CPU. the main memory is the central storage unit of the computer system. it is relatively large and fast memory used 2 store the programs and data during the computer operation.main memory communicates directly with the CPU. main memory includes RAM and ROMs. devices that provide backup storage are known as auxillary memory. auxillary memory are relatively slow in comparision to the main memory. auxillary memory includes flash memory,magntic disks and floppys. main memory is located inside the CPU but auxillary memory is located out the CPU.
Example of main memory of computer?
RAM or Random Access Memory is Tempory memory which your computer uses to load programs such as windows or games Your Hard Drive is an example of permanent memory on your computer where you can save documents/games etc. So when you load up your PC the computer reads the HD and loads up your OS (eg Windows) into your RAM.
Which area of the computer holds the data and instruction that are about to be used by the central processing unit?
MAIN MEMORY
What are the three main components of computer?
Processor, Memory, and Hard Drive
