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.
Read-only memory, or ROM, is a form of data storage in computers and other electronic devices that can not be easily altered or reprogrammed. ROM in non-volatile and the contents are retained even after the power is switched off.
RAM allows the computer to read data quickly to run applications. It allows reading and writing.
ROM stores the program required to initially boot the computer. It only allows reading.
