Booting is the process of restarting a computer or its operating system software. It starts with switching on the computer and ends when the Operating System is loaded into main memory and the computer is ready to take commands from the user.
Booting is of two types :
1. Cold booting: When the computer is started after having been switched off.
2. Warm booting: When the operating system alone is restarted after a system crash or freeze.
