What is BIOS Computer – BIOS (basic input/output system) is the program used by the computer microprocessor to start the computer system after it is turned on. It also manages the flow of data between the computer’s operating system (OS) and attached devices, such as hard disks, video adapters, keyboards, mice, and printers.

What is Computer BIOS

The term BIOS was first coined in 1975 by American computer scientist Gary Kildall. It was incorporated into IBM’s first personal computer in 1981 and, in the years to come, gained popularity on other PCs, being an integral part of the computer for some time. However, the popularity of BIOS has waned in favor of a newer technology: Unified Extensible Firmware Interface (UEFI). Intel announced plans in 2017 to discontinue support for legacy BIOS systems in 2020, replacing them with UEFI.

The main use of BIOS is to act as an intermediary between the OS and the hardware they run on. The BIOS is theoretically always an intermediary between the microprocessor and I/O device control information and data flow. Although, in some cases, the BIOS can arrange for data to flow directly into memory from a device, such as a video card, which requires a faster data flow to be effective.

The BIOS is included with the computer, as the firmware on the chip on the motherboard. On the other hand, an OS like Windows or iOS can be pre-installed by the manufacturer or vendor or installed by the user. The BIOS is a program accessible by the microprocessor on a programmable read-only memory (EPROM) chip that can be erased. When the user turns on their computer, the microprocessor passes control to the BIOS program, which is always located in the same place in the EPROM.

When the BIOS boots the computer, it first determines whether all the necessary attachments are present and operational. Any piece of hardware that contains files that the computer needs to start is called a boot device. After testing and confirming that the boot device is working, the BIOS loads the OS — or its essential parts — into the computer’s random access memory (RAM) from the hard disk disk or diskette drive (boot device).

That’s a brief understanding of the BIOS from me, hopefully this article can help those of you who are looking for information about the BIOS. That’s all from me, sorry if there are any wrong words from me as the author of this article and thank you for taking the time to visit the articles I made and for visiting our my method website.
