CPU - Answer-Central Processing Unit 3 Main Parts to a CPU - Answer-Arithmetic Logic Unit (ALU) Control Unit (CU) Input Output (IO) ALU - Answer-Arithmetic Logic Unit Main Part on the CPU CU - Answer-Control Unit Main Part on the CPU IO - Answer-Input Output Main Part on the CPU Central Processing Unit - Answer-Brains of your PC Located on Motherboard 3 Types of Cache on CPU - Answer-L1 - Primary (on the chip/die) L2-Secondary (in the case) L3-(on the mother board) Where is L1 Memory located? - Answer-on the chip/die on CPU on the motherboard. It's extremely fast but relatively small, and is usually embedded in the processor chip (CPU). Where is L2 Memory located? - Answer-in the case on the CPU. Usually bigger than L1. It may be located on the CPU or on a separate chip or coprocessor with a high-speed alternative system bus interconnecting the cache to the CPU, so as not to be slowed by traffic on the main system bus. Where is the L3 Memory located - Answer-on the motherboard on the CPU. It's specialized memory that works to improve the performance of Primary and Secondary memory. It can be significantly slower than these, but is usually double the speed of RAM. Cache memory - Answer-Provides read buffering for the CPU CPU memory, is random access memory (RAM) that a computer microprocessor can access more quickly than it can access regular RAM
