 CENTRAL PROCESSING UNIT Definition
We define CENTRAL PROCESSING UNIT |
CENTRAL PROCESSING UNIT - Think of this as the brains of the computer. When most people think of processors, they think of Intel, AMD, Motorola, or IBM. The Pentium 4 and Athlon are popular CPUs. The CPU's first instruction is to check the system BIOS and do what the BIOS tells it. The CPU is designed to run a group of instructions, or instruction set. CPU instructions can consist of adding together numbers, subtracting, fetching information from memory, and numerous other simple functions. The computer's operating system feeds the CPU instructions after the BIOS locates the operating system and puts it into main memory. |
