The Importance and Functions of the Basic Input-Output System (BIOS)
Introduction
Nowadays, many computer users around the world encounter a problem regarding Basic Input-Output System (BIOS). It is usually seen when a computer failed to shut down successfully where one can read the phrase “Enter BIOS

Knowing about the BIOS is the key to understanding your computer and making it perform at its optimal capabilities” (BIOSman Inc., para. 1).
(BIOSman Inc., 2012 para. 2) stated that BIOS stands for Basic Input Output System is the program that stores configuration details about computer hardware and boot up your computer. When you turn on your computer it loads configuration data into main memory, check your hardwares, then it loads the operating system.
(BIOSman Inc., 2012 para. 12) said that for the people who don’t have any idea what bios on your PC, when you turn on your PC.

(RR, 2012 para. 4) stated that traditional BIOS firmware is included on a computer motherboard as Read Only Memory (ROM). This means that the system is accessible but is not dynamically written to the way that a computer's hard drive is during operation. A battery on the motherboard keeps the data on it intact, even when the computer is turned off while not in use. Although sometimes confused with a Complementary Metal Oxide Semiconductor (CMOS), the BIOS refers to the firmware on the motherboard while the CMOS is the physical location where the date and system configuration data are stored.
