The BIOS is the input and output system incorporated by default in our motherboard, which helps to configure and manage the components of the same. But wait, what is BIOS and what is it used for?
With it you can reduce and optimize the speed of your CPU from BIOS and even make a backup or backup of the BIOS.
It happens that we have had to correct any error in the computer, and we find certain information that says that we must make configurations from the BIOS.
Or it could be device recognition issues, RAM reading, Fan Cooler speed deficiencies, or temperature issues.
All of these things are closely related to our basic entry and exit system . And we must enter it from MacBook, for example, to change or undo certain parameters that allow us to establish the operation of some element of the hardware in the way we want.
These types of needs are very common, since, depending on the card manufacturer, different firmware configurations can be found.
If you need to have a notion of what BIOS means and what its functions are, you may need to continue reading this article, it will provide you with important information about its capabilities.
What does BIOS mean?
Before answering the question What is BIOS and what is it used for? We must understand the origin of its name. What does BIOS mean ?
The word comes from the acronym ” Basic Input and Output System ” which in Spanish means: basic input and output system. In this are certain instructions or parameters stored on a chip on the motherboard of our PC.
This means that from these instructions we will be able to manage the behavior of our integrated components and peripherals according to the capacities that our board can handle.
His name also refers to the Greek word “life.” It is a fairly accurate and fun word game, because it is responsible for our PC starting .
BIOS features and capabilities
It is important to know what the BIOS is and what it is used for, if we want to make any important hardware changes to our personal computer, this is a sophisticated tool and quite useful when it comes to customizing our components.
start
One of its main functions is to carry out a kind of review called POST or AutoTest . In which it verifies that all the integrated components and peripherals of our equipment are working correctly.
Among them the RAM , our hard drive, the graphics card (or chipset if there is no card installed), processor, input devices, among others.
That is, all those connected elements that the BIOS recognizes and allows our PC to start satisfactorily.
An important piece of information about this element is that it usually sends the test information to the RAM card , since it is faster to analyze data, and speeds up the boot process.
Date and Time
Another of its functions is the recording of time. It stores the date and time of the equipment, which is stored in a memory section called “ ROM Memory ”.
Data transit
The third function is the ability you have to manage data movement between the operating system and installed hardware . Through it, the user is able to change the basic configuration of the devices.
In addition, the BIOS allows you to enable or disable some components, in case one is giving problems and does not allow an optimal boot, or it is simply some element that we do not use.
Using this same configuration, you can determine the clock frequency, a procedure called “ Overclocking ”,
Overclocking is generally used to force higher performance from our CPU or GPU (it can have serious consequences on some motherboards).
Security
Finally, the basic input / output system has a feature that allows you to assign a password to access the BIOS, for security purposes.
