What is a function of the bios?

The BIOS (Basic Input Output System) is firmware stored on a motherboard chip that performs essential tasks such as: - Initializing hardware components like CPU, RAM, and storage devices - Performing the POST (Power-On Self-Test) to check system health - Loading the operating system from the boot device - Providing an interface for hardware configuration settings Essentially, BIOS acts as the bridge between the computer hardware and the operating system.
