4. Write the basic differences between RAM and ROM.

Ans:

RAM	ROM
RAM stands for Random Access Memory.	ROM stands for Read Only Memory.
It is a volatile (temporary) memory.	It is a non-volatile (permanent) memory.
Data is lost when the power supply is turned off.	Data remains stored even when the power supply is turned off.
It stores data and programs that are currently being used by the computer.	It stores permanent instructions required to start and operate the computer.
RAM can be read from and written to.	ROM is mainly used for reading stored instructions.
It helps the computer work faster while running programs.	It contains important startup instructions of the computer.
