Booting a system

Booting a computer system is a process which involves loading an operating systems (OS).This happens after POST operation.On general purpose computers, the boot process begins with the execution of an initial program stored in boot ROMs or read in another fashion.
There are two types of booting.

• Cold booting
• Warm booting

A cold boot is a boot process in which the computer starts from a powerless state. Foe an active system, it requires one to shutdown normally -> power off the system -> Wait for some time -> power on it -> start the system.

A warm boot is initiated by pressing Ctrl + Alt + Delete key combination or pressing reboot button.

The cold boot allows the system to clear all contents of memory/ RAM. Warmbooting decreases load on electronic components
