- Interprets and carries out the basic instruction that operate a computer

Function : Direct and coordinates most of the operation in the computer

Component of Processor
i. Control Unit
ii. Arithmetic Logic Unit ( ALU )

  • Step 1 : Fetch 
- Control Unit obtain the math's problem instruction and data from memory
  • Step 2 : Decode
- The Control Unit translate the math problems instruction and send the instruction and send to the ALU
  • Step 3 : Execute
- The ALU performs calculation an the Data
  •  Step 4 : Store
- The results of the math problem are stored in memory (RAM)
