The BIOS firmware is responsible for setting up computer hardware when the system starts up and provides essential services that operating systems and applications need while running. UEFI (Unified Extensible Firmware Interface) represents a modern advancement over traditional BIOS, created to address its significant limitations. This updated technology offers several key benefits including stronger security features, a pre-boot interface that can be tailored to user needs, compatibility with high-capacity storage drives, and faster startup times.
