 Bios :- 

What is Bios? This is very comman question of mostly people who use desktop/laptop So here I am going to give some points about Bios So people can have some basic idea about bios.The term BIOS is invented by Gary Kildall .
1.BIOS stands for Basic input output system.2.It is the first software to run by pc when it turned on.3.The main function of bios is to initialize and test system hardware and load operating system.4.It provides a  consistent way for application and programs to communicate with system hardware like keyboard ,mouse and other I/O devices.5.Bios is stored in a non volatile ROM chip on the motherboard .6.Now its is stored in EEPROM chip so its is upgraded easily without removing chip.
