9 PC Terms Every Beginner Should Learn (So You Don’t Get Ripped Off)
7. BIOS/UEFI: The Gateway to System Configuration

The Basic Input/Output System (BIOS) or its modern counterpart, Unified Extensible Firmware Interface (UEFI), is the firmware that initializes hardware during boot-up and provides runtime services for operating systems. Understanding how to navigate BIOS/UEFI settings can be crucial for troubleshooting, upgrading hardware, or optimizing performance. Features like boot order, hardware monitoring, and overclocking settings can be accessed through this interface. Familiarity with BIOS/UEFI can prevent boot issues and enhance system stability, allowing users to unlock advanced features and maintain control over their PC's configuration.
