BIOS is the abbreviation of "Basic Input Output System" in English, and its Chinese name is "basic input output system" after literal translation. It is an industry standard firmware interface on IBM PC compatible systems. The word BIOS first appeared in CP/M operating system in 1975. BIOS is the first software loaded when a personal computer is started.
In fact, it is a set of programs solidified on a ROM chip on the computer motherboard, which stores the most important basic input and output programs, self-checking programs after starting up and self-starting programs of the system. It can read and write the specific information of system settings from CMOS. Its main function is to provide the lowest and most direct hardware setting and control for the computer. In addition, the BIOS also provides some system parameters to the operating system. The change of system hardware is hidden by BIOS, and the program uses BIOS function instead of directly controlling the hardware. Modern operating system ignores the abstraction layer provided by BIOS and directly controls hardware components.
Nowadays, this system has become the target of some virus Trojans. Once this system is destroyed, the consequences are unimaginable.
