The Von Neumann Architecture

The Von Neumann Architecture

1. The way a computer works is through a simple set of things what are input-process-output

   • INPUT-PROCESS-OUTPUT
     • INPUT
       • KEYBOARD
       • MOUSE
     • OUTPUT
       • SPEAKERS
       • MONITOR
       • PROJECTOR
     • PROCESS

2. The cycle will go on forever unless it is told to end or stop

   • Program
     • 1.Input Number
     • 2.Multiply Number By Itself
     • 3.Output Number
     • 4.End

3. PC-Holds the address of the next instruction

4. MAR-Holds the address of where the data is

5. MDR-Holds the far fetched data

6. FETCH

   • DECODE
     • EXECUTE

7. CONTROL UNIT=Sends signals to control how data moves around the CPU

8. PC

   • MAR
   • CPU
     • CU
     • ALU
       • CACHE
       • ACC
         • MDR

9. There are 4 different registers which are the:PC, MAR,ACC and the MDR

10. In the computer there is a fan to prevent it from overheating

11. ALU=Aritmatic Logic Unit

12. PROGRAM COUNTER

    • MEMORY ADDRESS REGISTER
      • MEMORY DATA REGISTER
        • ACCUMUULATOR
