You've probably heard or read somewhere about something called
BIOS is "something" very important on your computer (PC, PC).
Well, you may not have been clear what the BIOS and it is understandable that is often used interchangeably to refer to three different concepts from each other but it has great connection with
each other and then we number:
1. The BIOS, known as CMOS, is a small memory chip that you can see on your computer, currently used FLASH type memories. The name originates from the CMOS chip type initially used (many years): Complementary Metal Oxide Semiconductor CMOS =. Currently it is common for manufacturers of mainboards (motherboards) offer applications or utilities CMOS update via the Internet, but to decide to update the CMOS need to know it and know what to do (this is discussed in a future post) .
2. The B.I.O.S. better known as "Basic Input-Output System" is an extremely basic program programmed in assembly language is absolutely essential to our team since their purpose is to boot the computer (PC, PC), without it we could not do it.
When we turn on our PC (computer, computer) the BIOS (Which is stored in the CMOS) is copied to RAM and memorable then it is executed by the microprocessor, currently the mainboards can also run it directly from the BIOS CMOS.El load a series of pre-set configurations for himself and user-active system components (monitor, keyboard, mouse, storage devices), find the operating system and loads it into RAM transferring control of the PC (computer , PC) and then this "transfer" stops working for everything is handled by the OS.
3. The setup or CMOS-SETUP is an interface through which you can control and / or modify some BIOS settings which are stored in the CMOS part in this case acts as a RAM you need power and you will not miss each modified through the setup when we turn on our computer, the CMOS battery is fed to we see in our mainboard (motherboard)
