what are cpu device
When you first turn on or reset a PC, the CPU does not immediately execute application instructions. Instead, it begins with a process called the Power-On Self-Test (POST), which checks the hardware components to ensure they are functioning correctly. Once POST is complete, the CPU loads the operating system from the storage device into memory, after which it can execute application instructions as the user interacts with the system.
