What is the BIOS? What is his job? Here's all you need to know about BIOS

What is the BIOS? The BIOS is a shortcut to the Basic Input Output System. I do not really like the complicated explanations, and I do not like to introduce you to the BIOS as stated in Wikipedia or Google or I do not know, we are here to simplify the concepts, so let me tell you what BIOS is in a way Easy to use, my friend has a computer, this computer is installed by assembling a set of hardware: random memory RAM, hard drive, graphics card, processor and so on, all installed on a large chip called the mother card, good yet, We do not have any system, tool or hardware that checks these tools on the motherboard It leads us to not work the computer, Rabah, where is the problem? Is it ram? We need to install it and see it, then run the computer and the same problem. Simply, what we need in this case is a system called firmware, a system that the user can not access, program or modify. He does not care if there is a system installed in the computer, what is important is to verify that the hardware is good and strong and works to fit with the computer and its system, therefore, the creation of a successor system based on this principle, The BIOS is called. - What is the BIOS? The basic bios function, and the focus with me is not the only one, but the basic, is to work as a link between hardware and software, if there is a problem, for example RAM computer, the computer will mostly not work and the system will not appear, but we need a sign or something we know The problem with RAM is the computer, here comes the role of bios, which tells us clearly through the so-called BIOS Bips, I will explain all this, your computer, let me tell you how the computer works when you click on the power button: 1 - If you click on the power button and there is no electrical passage of the device, it is often in the recharge box, and of course is responsible for the passage of electricity, so here has nothing to do with the order. 2 - Once the power is confirmed and the power button is pressed, the BIOS is activated. The BIOS verifies that the processor is fine, in place, and then works on the graphics card as well. If not, it will notify you via BIOS Bips (I will explain it to you). Next paragraph only patient). 3 - If the processor is fine, it passes to check the random memory or RAM, if there is any problem where it does the same thing and notifies you through the BIOS Bips (patience, patience and the key to the vagina will explain everything you need to know about the BIOS Bips). 4. Then the BIOS checks the inputs, such as the keyboard, mouse, printer, etc., so sometimes my friend, when inserting a USB key refuses to access the system and hangs the computer, because the USB comes before testing the hard drive, Through the Boot Options and is the fifth stage. 5. The BIOS checks the Boot Options and starts to search for the system from the boot options (hard disk, CD, flash ...) 6 - Then check the rest of the Hadroir, when everything is fine, the system is taken off, if not either to show you the BIOS Bip or to show the error in a black screen according to the problem of the radar. All this my friend is in a very very few seconds, a fantastic speed is not it. - What are the BIOS Bips: The BIOS is smart, my friend, he knows you're having problems with some type of hardware, but what if the damaged hardware is the same as the graphics card? How will you get the error? And it tells you where exactly the error is? Beyond this problem, there is the so-called BIOS Bips, the sounds of "Biep" issued by the computer when he finds a fault in the hardware the first three stages above, but the BIOS Bips varies by type of radar, yes, we find that, for example in the case of failure in RAM, we find that the BIOS issued 3 "Beep" lengthy, the reputation of the problem of Alram directly, if you hear example 5 "Baiib" long, the problem of graphic cart, and so on. Are there other BIOS functions? The BIOS controls many things. It is able to access the CMOS chip to modify the time and time of the computer, as well as modify many things according to the version of the BIOS you carry, as well as able to control the type of computer input and order, and also The Boot Options are listed above, as you can see in full, in detail, and remember, my friend, that the BIOS is not faulty, but it is difficult to solve, sometimes when the BIOS is down, you can only turn your computer away. , Try not to mess with it a lot if you do not understand the course well, it may lead to things that do not praise the punishment.
