What is Bios?
Ans. On x86-based computers, the set of essential software routines that test hardware at startup, start the operating system, and support the transfer of data among hardware devices is called the BIOS. It is stored in read-only memory to be executed when the system is turned on and is very critical to performance although usually invisible to computer users.
The BiOS Initiative emerged in response to current business and legal landscapes which prevent many groups within the developed and developing world from accessing and harnessing biological science technologies. The initiative will foster democratic innovation in the application of biological technologies through the astute use of intellectual property informatics and analysis, innovation system structural reform and cooperative open access technology development activities. The objective of the BiOS Initiative is to create a public-spirited and public-good based initiative with respect to biological innovations. The BiOS Initiative will develop, promote and validate a new means for the invention, improvement and delivery of biological technologies.
BIOS or Basic Input/Output System is the first program accessed by the processor during start up to ensure that all the other basic programs, hard drives, ports, peripherals and the central processing unit are in good working condition. BIOS is different from the computer’s operating system. The operating system resides in the hard drive and provides the user interface that can be seen on the screen after start up. The BIOS program, on the other hand, can be found right in a flash memory chip or ROM located in the motherboard. It is the basic requirement for booting a computer.
BIOS is an acronym for Basic Input/Output System. It is the boot firmware program on a PC, and controls the computer from the time you start it up until the operating system takes over. When you turn on a PC, the BIOS first conducts a basic hardware check, called a Power-On Self Test (POST), to determine whether all of the attachments are present and working. Then it loads the operating system into your computer’s random access memory, or RAM. The BIOS also manages data flow between the computer’s operating system and attached devices such as the hard disk, video card, keyboard, mouse, and printer. The BIOS stores the date, the time, and your system configuration information in a battery-powered, non-volatile memory chip, called a CMOS (Complementary Metal Oxide Semiconductor) after its manufacturing process. Although the BIOS is standardized and should rarely require updating, some older BIOS chips may not accommodate new hardware devices. Before the early 1990s, you couldn’t update t
A BIOS (Basic Input/Output System) is an electronic set of instructions that a computer uses to successfully start operating. The BIOS is located on a chip inside of the computer and is designed in a way that protects it from disk failure. A main function of the BIOS is to give instructions for the power-on self test (POST). This self test ensures that the computer has all of the necessary parts and functionality needed to successfully start itself, such as use of memory, a keyboard and other parts. If errors are detected during the test, the BIOS instructs the computer to give a code that reveals the problem. Error codes are typically a series of beeps heard shortly after startup. The BIOS also works to give the computer basic information about how to interact with some critical components, such as drives and memory, that it will need to load the operating system. Once the basic instructions have been loaded and the self-test has been passed, the computer can proceed with loading the
