The main function of the BIOS (Basic Input Output System) is to boot up an operating system on a PC. It does this by first identifying and testing all hardware components (including the hard disk and floppy drives), and then by locating a valid operating system to which it can transfer control.
A computer's Basic Input Output System and Complementary Metal-Oxide Semiconductor together handle a rudimentary and essential process: they set up the computer and boot the operating system.
BIOS may refer to any of the following: 1. Short for Basic Input/Output System, the BIOS (pronounced bye-oss) is a ROM chip found on motherboards that allows you to access and set up your computer system at the most basic level. The picture below is an example of what a BIOS chip may look like on a computer motherboard.
With the BIOS performing virtually all of its functions during startup, this effectively password-protects the operation of the whole computer. However, resetting a lost BIOS password can be time ...
The term BIOS (Basic Input/Output System) was created by Gary Kildall and first appeared in the CP/M operating system in 1975, describing the machine-specific part of CP/M loaded during boot time that interfaces directly with the hardware.
BIOS which is the acronym of Basic Input-Output System and is pronounced byee-oss, is a read-only memory (ROM) chip found in computers to start it and to ensure its proper functioning post it. Located in the motherboard of the machine, it is also known as ROM BIOS , System BIOS, or PC BIOS and works in close proximity with the CMOS ...
The BIOS software has a number of different roles, but its most important role is to load the operating system. When you turn on your computer and the microprocessor tries to execute its first instruction, it has to get that instruction from somewhere.
BIOS (basic input/output system) is the program a personal computer's microprocessor uses to get the computer system started after you turn it on. It also manages data flow between the computer's operating system and attached devices such as the hard disk, video adapter, keyboard, mouse and printer.
BIOS instructs the computer on how to perform a number of basic functions such as booting and keyboard control. BIOS is also used to identify and configure the hardware in a computer such as the hard drive , floppy drive , optical drive , CPU , memory , etc.
Some functions controlled by the BIOS include verifying that all the computer hardware is working properly, managing communications between the computer and its peripherals, such as the printer and monitor, and making sure the system clock and computer drives are working properly.
