Basic functions performed on startup

When the power button is switched on immediately a program runs on computers. This program is called BIOS. BIOS stands for Basic Input Output System.

It performs a basic test known as POST (Power On Self Test) when the computer turns on. Here BIOS will check all the connected devices and raise an error if any device is not working properly otherwise loads the operating system.

Login and Logout

Every computer has some users. These users ensure security concerns. Likely every door has a lock and key, and every computer system has a username and password to prevent the usage of computers by unauthentic users.

On startup users generally enters username and password. This process is called login. After finishing the work user clicks on Logout to exit from the system.
