Basic Input / Output System, or often called the BIOS is a program written in assembly language in charge of organizing the functions of the hardware / hardware contained on the computer.
Unlike the operating systems that are on the hard drive, usually located in the BIOS chip flash memory or ROM which is made of Complementary Metal-Oxide Semiconductor, or commonly referred to as CMOS.
Usually people call the battery attached to the motherboard as the CMOS battery. The battery is what serves to maintain the date and other settings that has been set by the user that is not lost even when your computer is turned off.
BIOS has some important tasks such as loading the operating system or commonly referred to as the boot. BIOS is also tasked with providing instruction on a microprocessor to turn on the computer.One of the instructions ordered by the BIOS on the microprocessor is
the Power On Self Test (POST), which serves to test the operating status
of all hardware on the computer.
Other instructions given to the microprocessor is activate the BIOS chip contained in some other components of the computer such as SCSI and graphics cards, check and manage computer peripherals through low-level routines during the startup process takes place.
In addition, other things are done by the microprocessor clock management, hard disk and other settings. The function of the BIOS on the Computer One of the main tasks undertaken by the BIOS are set early stages of the startup process and ensuring that operating systems have actually been loaded into memory.
Additionally, BIOS functions do the following:1. Run Command Power On Self Test (POST)
One must do before installing the operating system on a computer is to check a number of existing devices on the computer.
In addition, the BIOS can also provide information on the specifications of the hardware found on the motherboard.2. Set Basic Configuration on a Computer
Generally, the BIOS to set the configuration to other devices based on their respective functions.
These configuration settings are usually exploited by some people, especially gamers to improve the performance / performance of a computer or often referred to as overclocking.3. Provide Basic Information on Computer
In addition to running the POST command and set the basic configuration of the computer, the BIOS is also in charge of providing basic information on how the interaction of each essential devices found on the computer as drives and memory which will be in charge of loading the operating system.
Components in the BIOSSo that the BIOS can carry out their duties properly. So we need some supporting components include:
1. The BIOS Setup program
This program serves to change the configuration of the computer such as the type of hard disk, disk drives, power management, performance, and others as the user desires.
Generally BIOS hides the details of the device that can be fairly complicated, so it needs some skill if we want to know more about the details of these devices.2. Driver
The function of this driver is intended for computer hardware devices such as VGA, input devices, processor and some other device to the base operating system 16 bit which is a family of DOS.3. Program Top Bootstraper
The program is instrumental in the process of booting into the operating system that we have installed previously.
How to Work BIOS?
Initially BIOS initialization process where in the process the user can see the specifications of the computer such as the amount of memory, the type and capacity of the hard drive, VGA card information and others. In addition, also to check the BIOS ROM devices, such as hard disk and do the testing of the RAM.After all the testing and checking of the device is completed, the next step should do is find a location BIOS booting to enter the operating system that has been installed.

Conclusion
BIOS, or Basic Input Output System is a program that aggregates information and configuration of the devices contained on a computer.BIOS controls the boot process when the computer starts. Additionally, the hardware found on a computer can also be set via the BIOS in order to work as closely as possible.
