BIOS Settings are a set of configurations stored in a computer's firmware that control hardware settings and system behavior. They allow users to manage various components, such as the CPU, RAM, and hard drives, ensuring that the operating system can communicate effectively with the hardware. Accessing the BIOS typically involves pressing a specific key, like F2 or Delete, during the computer's startup. Users can adjust settings like boot order, enabling or disabling hardware features, and setting system clocks. Properly configuring BIOS Settings can enhance system performance and stability.
