I do not know which is the main memory. I want to find the difference between two memory of the computer. They are:
RAM + ROM
ROM = Read Only Memory = Read-Only Memory
Random Access Memory = RAM = Random Access Memory.
The ROM contains all the system resources required to operate and read at the beginning and every time you need the system. The RAM is used by normal applications, all programs that start and stop, etc.. What is the difference here if we get upgrade on the same.
