A) Basic Input Output System

BIOS stands for “Basic Input/Output System” in computer systems. It is a firmware or software that is stored on a computer’s motherboard and is responsible for initializing and controlling the computer’s hardware components during the boot-up process. The BIOS performs a series of self-tests, detects and configures hardware devices (such as the CPU, RAM, and storage devices), and loads the operating system into the computer’s memory.

The BIOS also provides a basic interface for configuring various hardware settings and can be used to modify settings like boot order, system time, and security features. While the term “BIOS” is commonly used, many modern computers have transitioned to using a more advanced firmware known as UEFI (Unified Extensible Firmware Interface), which serves a similar purpose but with more features and capabilities than traditional BIOS.
