The content of computer memory which is non-volatile, even when the power goes off is :
Explanation
Computer memory is classified into volatile and non-volatile types based on data retention. ROM (Read-Only Memory) is non-volatile, meaning it permanently stores instructions and data that are not lost when the power is switched off. It is essentially used for storing the BIOS (Basic Input/Output System) which boots up the computer.
- RAM (Random Access Memory) is volatile memory. It is the main memory used by the CPU to store data currently in use, but it requires a constant power supply to retain information.
- REM is not a standard hardware memory term; in programming languages like BASIC, it stands for 'Remark' and is used for comments.
