The Von Neumann Architecture

The Von Neumann Architecture

1. Input-Process-Output

   • Input
     • Keyboard
     • Mouse
   • Process
   • Output
     • Speakers
     • Moniter
     • Projecter

2. Program

   • 1. Imput number
   • 2. Multiply number by itself
   • 3. Output number
   • 4. End

3. Inside a computer is a fan to prevent it over heating

4. Calculators are kind of computers

   • Imput
     • Numbers
   • Progress
     • Solving
   • Output
     • Result

5. Fetch

   • Decode
     • Execute

6. Registers

   • PC
     • Holds address of next instruction in memory
   • MAR
     • holds address of where data is to be fetched/stored
   • MDR
     • holds data to be fetched from or to be written to the memory
   • ACC
     • holds results of calculations

7. PC-MAR-MDR-ACC

   • Increment-add one

8. End=Stop

   • The cycle will go on forever unless it is told to end/stop
