RAM and ROM
RAM stands for Random Access Memory
ROM stands for Read Only Memory
It is also called main memory. Program data is copied into RAM before the CPU can run the program. RAM is usually measured in gigabytes. The more gigabytes of RAM a computer has, the more programs and operations it can handle at the same time.
