The Role of BIOS/UEFI in Computer Hardware Components
When you turn on your computer, before any operating system loads or programs start running, one crucial component kicks into action — the BIOS or UEFI. These essential firmware interfaces serve as the foundation of your system’s hardware communication, ensuring everything works as it should. Let’s explore the role of BIOS and UEFI, their impact on hardware performance, and how adjusting these settings can improve your computer’s functionality. What is BIOS/UEFI? BIOS (Basic Input/Output System) and UEFI (Unified Extensible Firmware Interface) are the first programs to run when you power on your PC. Their primary function is to initialize and test the hardware components in your computer and load the operating system from your storage device.
