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.
