When we first start the computer or laptop and press the ESC button as fast as possible, the kit will enter into an arrangement that may not be understood by many people. Well, the settings when the computer first appears or laptop is turned on is the BIOS.

Definition of BIOS

Basically, the BIOS is an abbreviation of the Basic Input System. Literally, the BIOS is a program that is written in the form of assembly language and has the task of managing a number of functions on computer hardware.

The BIOS system is different from the operating system inside the hard drive. The difference between the operating system and BIOS lies in the flash memory chip. In addition, this BIOS is also located in the flash memory chip section or in the CMOS section. Well, this CMOS is a battery that attaches to the motherboard. The function of CMOS is to maintain date settings and other settings that have been set by the user so they do not change when the computer or laptop is turned off.

BIOS function

As was discussed earlier that the BIOS has the task to set the initial stages of various initial processes of computers and laptops. in addition, the BIOS can also ensure that the operating system is really running well in memory. Some other BIOS functions are as follows.

Can run POST or Power On Self Test commands

Before we install an operating system on a computer or laptop, we must know in advance what kind of device is in the computer or laptop used. of course it will be very waste of time if we dismantle one by one the various existing devices.

Therefore, with this BIOS, we can understand the full specifications installed on a computer or on a laptop. That way, we can install the operating system based on specifications contained in the computer or laptop.

Perform basic configuration settings

In general, the BIOS can set the basic configuration on other devices based on the functions of each device. This arrangement is always done by several people, especially by some gamers. Its function is to improve performance or performance on a computer device. The term that is often used in these conditions is called overclocking.

Overclocking itself is an action to increase the clock rate on the hardware. Some examples of overclocking can be found on the CPU or on the GPU. Even so, some other components can also be overclocking.

Can provide basic hardware information

Besides being able to provide hardware information that is used on computers or laptops, the BIOS can also provide basic information about the modes of interaction of each device on the computer or on the laptop. for example just like the relationship between the drive and memory so that it can function properly on the operating system. That way, users can find out whether some devices such as hard disk, VGA, RAM, can run perfectly.

BIOS components

In the BIOS there are many driving components to be able to maintain the performance of a computer or laptop. for more details, the following review.

BIOS program

First is the BIOS program itself. This program has the benefit of being able to change computer configurations on hard disk types, disk drives, computer performance, power management, and also other things according to user requests. In general, the BIOS can hide some details on the device. Therefore, special expertise is needed so that users can see the desired device details.

Driver

The second component is the driver. The main function of this driver is for computer hardware. For example like the VGA. Input Devices, Processors, and various other devices in the basic 16bit operating system section.

Bootstraper

The last part is the bootstraper program. The program is responsible for booting on a computer or on a laptop. so, the boot process that you often see when you first turn on your computer or laptop comes from this device.

Working System BIOS

The first time the BIOS runs, the first thing to do is to initialize it. The process can make the user see the specifications of the computer or laptop in it. Examples of simplicity such as the amount of memory used, the type of memory, hard disk capacity used, information on the type of VGA used, and many others.

The BIOS will also check other devices whether the device can be used properly or not. how to check through the BIOS is to do a test. Some devices that are tested by the BIOS are hard disk, RAM, VGA, and various other devices installed on computers or laptops.

After the test process has been done, the next step is the BIOS to find the boot location. This is done to enter the operating system that has been installed on the computer or laptop used.

That’s the understanding of the BIOS on a computer or laptop. From the above explanation, we can conclude that the BIOS is very important in the presence of a computer system. May be useful.
