Q. What do you understand by RAM and ROM?

Answer :-

RAM (Random Access Memory):-

It is a read/write memory as it is possible to both read from and write to location within RAM. It is used for primary storage in computers to hold active information of data and instructions. The RAM is a volatile memory as it loses its contents when the power is switched off or interrupted.

ROM (Read Only Memory):-

It is a read-only memory, i.e., the data and instructions are placed in the ROM at the time of its manufacturing and can't be changed thereafter.
ROM is slower than RAM and is used to hold certain essential instructions to check basic hardware components such as booting, procedures to load operating system, and frequently-needed functions.
