The main difference between RAM (Random Access Memory) and ROM (Read-Only Memory) is that RAM is volatile memory, meaning it loses its contents when the computer is powered off, while ROM is non-volatile memory, meaning it retains its contents even when the power is turned off. RAM is used for temporary storage of data and program instructions that are actively being used by the CPU, while ROM is used to store firmware or permanent system instructions that are not expected to change.
