With it you can reduce and optimize the speed of your CPU from the BIOS and even make a backup or backup of the BIOS.
It happens that we had to to correct any error in the computer and we find some information that says that we need to make configurations from the BIOS.
Or it could be problems recognizing the device, reading the RAM, fan speed deficiencies or temperature problems.
All of these things are closely related to ours entry and exit system of base. And we have to enter it from MacBook, for example, to change or cancel certain parameters that allow us to establish the operation of certain elements dell’hardware the way you want.
These types of needs are very common, as different firmware configurations can be found depending on the card manufacturer.
If you need to get an idea of what that means BIOS and what its functions are, you may need to keep reading this article, it will give you important information about its capabilities.
What does BIOS mean?
Before answering the question What is BIOS and what is it for? We need to understand the origin of its name. What does it mean BIOS?
The word derives from the acronym " Basic Input and Output System »Which in Spanish means: basic input and output system. In this there are some instructions or parameters stored in a chip on our PC motherboard.
This means that from these instructions we will be able to manage behavior of our integrated components and peripherals based on the capabilities our board can handle.
His name also refers to the Greek word "life". It's a pretty neat and fun pun, because it's responsible of the start of the our PC.
BIOS features and capabilities
It is important to know what the BIOS is and what it is for if we want to make any major changes all’hardware of our personal computer, this is a sophisticated and quite useful tool when it comes to customizing our components.
begin
One of its main functions is to carry out a kind of review called POST o Self test. In which it verifies that all the components and integrated peripherals of our equipment are working correctly.
Among these the RAM, our hard drive, graphics card (or chipset if no card is installed), the processor, input devices, among others.
That is, all those related elements that the BIOS recognizes and allows our PC to boot up satisfactorily.
An important fact about this element is that it usually sends the test information to the board RAM, because it is faster in analyzing data and speeds up the startup process.
Date and time
Another of its functions is time recording. Stores the date and time of the equipment, which is stored in a memory section called " Memory ROM «.
Data transit
The third feature is the ability to manage the flow of data between the operating system and the hardware installed. The user through it is able to modify the basic configuration of the devices.
Furthermore, the BIOS allows you to enable or disable some components, in case one gives problems and does not allow an optimal start, or simply it is some element that we do not use.
Using this same configuration, the clock frequency can be determined, 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).
Safety
Finally, the basic input / output system has a feature that allows you to assign a password to enter the BIOS, for security reasons.
