Which component stores the firmware that contains the first instructions executed when a PC starts?

Explanation:
The first instructions the CPU runs at startup come from firmware stored in non-volatile memory on the motherboard—the BIOS/UEFI chip. When power is applied, the processor has a fixed starting point in that firmware, which then performs the Power-On Self-Test, initializes hardware, and loads the operating system. RAM can’t hold this code because it loses contents when power is removed, and the CPU or GPU don’t store or originate these startup instructions themselves. The BIOS chip provides the persistent code that gets the system booted.
