c) Bitrate Input/Output System
d) Basic Information Output Source
Answer:
a) Basic Input/Output System
Explanation:
BIOS stands for Basic Input/Output System, and it is the firmware used to initialize and manage hardware during the startup process of a computer. It performs system checks and loads the operating system into memory when the computer is powered on.
The BIOS is stored on a chip on the motherboard and contains the basic instructions that enable the CPU to communicate with the computer’s hardware, such as the hard drive, RAM, and input/output devices.
The BIOS also allows users to configure hardware settings, such as the boot sequence and system clock, through a setup utility. Modern computers often use a more advanced system called UEFI, but BIOS is still widely recognized and used.
