What is BIOS?

BIOS stands for Basic Input/Output System. It's a firmware program that initializes and configures hardware components when a computer is powered on, and it's responsible for loading the operating system.
It acts as a bridge between the hardware and the operating system, ensuring everything is ready to function before the OS takes over.

Key Functions of BIOS:

Hardware Initialization: BIOS configures and tests the hardware components like the processor, memory (RAM), hard drives, graphics card, and input devices (keyboard, mouse).

Boot Process:

BIOS initiates the boot sequence, loading the operating system from the designated storage device (hard drive, SSD, etc.)

System Clock and Time:

BIOS manages the system's time and date settings.

System Security:

BIOS can be configured with security settings like passwords to restrict access to certain features.

Overclocking (in some implementations):

Some BIOS versions allow users to adjust clock speeds of components, like the CPU, to potentially improve performance, but this can also affect stability. Hardware Monitoring: BIOS can monitor system temperatures, voltages, and fan speeds.

Driver Updates:

Some BIOS implementations allow for updating drivers directly from the firmware interface.

Modern BIOS and UEFI:

Older systems used a type of BIOS called Legacy BIOS. Modern systems typically use UEFI (Unified Extensible Firmware Interface),
which is an evolution of BIOS with more advanced features and capabilities.
UEFI can handle larger storage devices (over 2TB), has a graphical interface, and supports network connections.
UEFI is expected to eventually replace BIOS entirely.

Accessing BIOS:

To access BIOS settings, you typically need to press a specific key (like F2, F10, Del, or Esc) during the computer's startup sequence.
The specific key varies by manufacturer and motherboard model.
The key is often displayed on the screen during the Power-On Self-Test (POST).
