The CPU- What you need to know

1. Types

   • RISC
   • CISC

2. Parts of

   • Control Unit
     • The CU, which is also called the controller, controls data moving through the processor, and controls the timing of operations and the instructions sent to the processor and the peripheral devices
   • Aritimatic and Logic unit
   • Immediate access store
     • A register is a small amount of fast temporary memory within the processor where the ALU or the CU can store and change values needed to execute instructions

3. Factors that effect performance

   • Cache size
   • Clock speed
   • Cores
   • What is Benchmarking
     • Is a test to assess the performance of a computer

4. Purpose

   • Fetch- Decode- Execute cycle
     • Decodes data
     • Execute instructions
     • Fetch data
   • Brain of the computer
   • The purpose of the CPU is to process data
