1.10 Neumann Architecture

✅ Neumann Architecture

explains how the computer works inside
architecture of a computer

• This way of explaining architecture a computer has been valid since 1945

☑️ 3 parts of computer in Neumann

• ✔️ A - Control Unit: CU
• brain/boss of the computer
• controls, sets the rythm of the computer

• give orders to the other units

• ✔️ B - Arithmetic-Logic Unit: ALU
• staff/workers of the computer
• part of the computer that really works/caculates

• use automatic gates = logic gates

• 🏠 both CU and ALU are inside the microprocessor, CPU

  • CPU: Central Processing Unit
  • CPU = CU + ALU
• ✔️ C - Main Memory Unit: MU
• = RAM
• storing information
• in a computer, secondary memory(harddisk) is not mandatory
• thus, in Neumann, we do not talk about secondary memory(harddisk) which is optional
• RAM is mandatory
