Computer Operator Interview Question: Difference Between RAM and ROM

RAM (Random Access Memory) and ROM (Read-Only Memory) are two types of memory in a computer system, each serving different functions:

RAM (Random Access Memory)

RAM is a volatile memory that temporarily stores data and instructions that the computer needs while it is running. It allows for quick access to data, enabling the CPU to operate efficiently. RAM is cleared when the computer is turned off and does not retain data when power is lost.

ROM (Read-Only Memory)

ROM is a non-volatile memory that stores firmware and software instructions that are permanently written during the manufacturing process. It contains essential programs that are needed to start up the computer system, such as the BIOS. ROM retains data even when the computer is powered off.

In summary, RAM is used for temporary data storage during computer operation, while ROM contains important permanent instructions for booting up the system.
