Question: What is BIOS (Basic Input and Output Software)?

BIOS, which stands for Basic Input/Output System, is a built-in software that initializes hardware during the booting process of a computer and provides basic functionality for the operating system. It is typically stored on a ROM (Read-Only Memory) chip on the computer's motherboard. BIOS performs essential tasks such as conducting power-on self-tests (POST), detecting and initializing hardware components like the CPU, memory, and storage devices, and providing a basic interface for configuring system settings. BIOS also facilitates communication between the operating system and the hardware. While modern computers increasingly use UEFI (Unified Extensible Firmware Interface) instead of traditional BIOS, the fundamental purpose remains the same: to initialize hardware and provide a bridge between hardware and software during the boot process.
