Explain in detail how main memory works.
What will be an ideal response?
The main memory is used by the computer when it is running a program. Values stored in a program’s variables are kept in this main memory as well as the byte-code of the program. Main memory consists of a long list of numbered locations called bytes. The number that identifies the byte is called the address. A data item can be stored in one or more of those bytes, and the address of the byte is then used to locate the data item when it is needed.
