Question

Give any four differences between RAM and ROM.

Hint:

RAM = Blackboard (Wipeable). ROM = Stone Carving (Permanent).

Answer 1

1. Volatility: RAM is volatile (data is lost when power is off), whereas ROM is non-volatile (data is retained without power).
2. Function: RAM is used for temporary storage of data currently in use by the CPU. ROM stores the startup instructions (BIOS) required to boot the computer.
3. Modifiability: Data in RAM can be read and written to easily. Data in ROM is typically "Read-Only" and difficult to modify.
4. Capacity: Computers usually have a larger amount of RAM (e.g., 8GB, 16GB) compared to ROM (a few MBs).
