All the instructions to start computer are stored in BIOS (Basic Input Output System ) at ROM. Whenever computer is started BIOS checks presence and status of RAM and input & output devices like keyboard, monitor, printer, disk drives etc. After checking these devices BIOS searches operating system in different drives. On finding operating system BIOS startups the operating system and hands over control of computer to operating system.

On start up the computer fetches information from BIOS. BIOS is a ROM. After that the computer loads OS from Hard disk into the RAM.
