The boot sequence is the process that a computer system undergoes to initialize and load the operating system from a powered-off state. It involves a series of steps managed by the BIOS or UEFI, including hardware checks and the loading of essential software components necessary for system operation.

A computer system is an integrated set of hardware and software components designed to process data and perform tasks according to user instructions. It encompasses everything from the central processing unit and memory to peripheral devices and operating systems, enabling the execution of applications and management of resources efficiently.

The BIOS, or Basic Input/Output System, is a firmware interface that initializes and tests hardware components during the booting process and provides runtime services for operating systems and programs. It is crucial for facilitating communication between the operating system and the hardware, ensuring that the computer starts up correctly and efficiently.

BIOS

UEFI (Unified Extensible Firmware Interface) is a modern firmware interface designed to replace the legacy BIOS, providing a more flexible and robust environment for booting operating systems and managing hardware. It supports larger boot drives, faster startup times, and enhanced security features like Secure Boot, making it essential for contemporary computing systems.
