UEFI
UEFI (Unified Extensible Firmware Interface) is a modern firmware interface that replaces the legacy BIOS (Basic Input/Output System) in computers. It initializes hardware components during the boot process and provides a standardized environment for the operating system to load, with features like secure boot, network booting, and support for large storage drives. UEFI is essential for modern computing systems, including PCs, servers, and embedded devices.
Developers should learn UEFI when working on system-level programming, embedded systems, or operating system development, as it is the standard firmware for most modern hardware. It is crucial for tasks like bootloader development, firmware updates, and implementing security features such as secure boot to prevent malware attacks during startup. Use cases include developing custom bootloaders, debugging hardware initialization issues, or creating firmware for IoT devices.
