Concept of booting

 

When the computer is switched on, a copy of the boot program is brought from ROM into
the main memory and all operating system files load into the RAM. This process is called booting. 

Booting Process is of two types – Warm and Cold

Cold Booting: When the system starts from initial state i.e. it is switched on, we call it
cold booting or Hard Booting.

Warm Booting: When the system restarts or when the Reset button is pressed, we call it
Warm Booting or Soft Booting.
