What does bios mean?
BIOS is the abbreviation of "Basic Input Output System" in English. When translated literally, the Chinese name is "Basic Input Output System". On IBM PC-compatible systems, it is an industry-standard firmware interface. The term BIOS first appeared in the CP/M operating system in 1975. BIOS is the first software loaded when a personal computer starts up.
In fact, it is a set of programs solidified on a ROM chip on the motherboard of the computer. It stores the most important basic input and output programs of the computer, the self-test program after power-on, and the system self-startup program. Specific information about system settings can be read and written from CMOS. Its main function is to provide the lowest and most direct hardware settings and control for the computer. In addition, the BIOS also provides some system parameters to the operating system. Changes to system hardware are hidden by the BIOS, and programs use BIOS functions instead of directly controlling the hardware. Modern operating systems ignore the abstraction layer provided by the BIOS and control the hardware components directly.
Today, this system has become the target of some virus Trojans. Once this system is destroyed, the consequences will be disastrous.
The word BIOS has a double meaning:
1. The abbreviation of the plural form of the English word Biography (Biography-Biographies-Bios), generally pronounced as /'baious /.
2. In the computer field, BIOS is the abbreviation of "Basic Input Output System", which is translated as "Basic Input Output System" and has the same pronunciation as the former. When the computer is running, it will first enter the BIOS, which plays a very important role in the computer system. Whether a motherboard has superior performance or not depends largely on whether the BIOS management functions on the motherboard are advanced.
BIOS is an important parameter (term) in the computer field.
