what is a bios?

Answer 1

(m)

BIOS, in computing, stands for Basic Input/Output System also incorrectly known as Basic Integrated Operating System. BIOS refers to the software code run by a computer when first powered on. The primary function of BIOS is to prepare the machine so other software programs stored on various media (such as hard drives, floppies, and CDs) can load, execute, and assume control of the computer. This process is known as booting up.

BIOS can also be said to be a coded program embedded on a chip that recognises and controls various devices that make up the computer. The term BIOS is specific to personal computer vendors. Among other classes of computers, the generic terms boot monitor, boot loader or boot ROM are commonly used.

While the name BIOS is an acronym, it may also be a play on the Greek word βίος (bios), meaning life. The term first appeared in the CP/M operating system, describing the part of CP/M loaded during boot time that interfaced directly with the hardware (CP/M machines usually had a simple boot loader in ROM, and nothing else). Most versions of DOS have a file called "IBMBIO.COM" or "IO.SYS" that is analogous to the CP/M disk BIOS.

Answer 2

BIOS stands for "Basic Input/Output System".
The built-in software that determines what a computer can do without accessing programs from a disk. On PCs, the BIOS contains all the code required to control the keyboard, display screen, disk drives, serial communications, and a number of miscellaneous functions.

The BIOS is typically placed in a ROM chip that comes with the computer (it is often called a ROM BIOS). This ensures that the BIOS will always be available and will not be damaged by disk failures. It also makes it possible for a computer to boot itself. Because RAM is faster than ROM, though, many computer manufacturers design systems so that the BIOS is copied from ROM to RAM each time the computer is booted. This is known as shadowing.

Many modern PCs have a flash BIOS, which means that the BIOS has been recorded on a flash memory chip, which can be updated if necessary.

The PC BIOS is fairly standardized, so all PCs are similar at this level (although there are different BIOS versions). Additional DOS functions are usually added through software modules. This means you can upgrade to a newer version of DOS without changing the BIOS.

PC BIOSes that can handle Plug-and-Play (PnP) devices are known as PnP BIOSes, or PnP-aware BIOSes. These BIOSes are always implemented with flash memory rather than ROM.

Answer 3

BIOS = Basic Input Output System

When your computer is as dumb as an Ox. When it wakes up it is simply a fast clock. THe BIOS is an integrated Circuit chip on your computer's motherboard that "boots" it up, i.e. telling it that it has a keyboard, a display, some memory and a hard drive. It tells the computer how to look to the hard drive to start booting the operating system.

Part of the BIOS is fixed information, some is programmable (what type of hard drive, Memory & CPU etc)

It can usually be accessed at start up by pressing some key/s the "DEL" key being the most common, but some use F1, F10, F12, Esc etc.

Hope this helps

Answer 4

The basic input output system. It is a computer chip on your motherboard on your computer. It provides the ability to change parameters, performance, hardware adaptability, virus protection, etc. The bios can be adjusted when you are booting up you have to hit F2, or F8 or DEL depending on the computer to access the bios to change parameters. Your computer may need to have things adjusted when making hardware changes, memory changes, etc. When you are done adjusting everything you exit and save the changes and the computer will go on and finish booting with the changes you made implemented. You can find details of the bios usually with the manual that comes with your motherboard or you can download the information from the company that sold you the computer you own. Sometimes the bios needs to be updated or "flashed" and special care should be taken when attempting this but is sometimes necessary when making hardware changes, etc.

SIMPLE B = basic I = input O=output S= system

When Pc starts up the OS (the big daddy - operating system)

search The thing called BIOS to understand what kind of hardware

and settings Ur Pc have So it can start up and go to Action...

Answer 6

You would need to find out who the maker of the board is. It might take some time searching on Google to see if you can find it. Then you would have to find a retail board that the company makes that is the same as your and flash the bios to that. It can be a lot of time searching and fooling around to get it. I have done it with one of my boards and even though it did work it was hardly worth the trouble. The boards were not sold to be overclockers and even with the retail bios might not give you much to work with. I was able to get my 2.8 ghz cpu up to 3.0 ghz so it was hardly even noticeable. You may be better off trying to overclock with software. like clockgen or set pll.

It is the program that let your computer work! Like windows!!
