'''Year 2'''
von Neumann Architecture is a type of computer architecture, based on the design created by John von Neumann in 1945.
 
  
Computer systems that use von Neumann Architecture contain three main components; the central processing unit (CPU), memory, and input/output devices (I/O), which are all connected together using the system bus.

Interrupts

*[[Interrupts]] {{partially done}}
The memory stores the information (data/program).
 
The processing unit handles computation/processing of information.
 
The Input receives the information from input devices such as mouse and keyboard.
 
The Output sends information out to devices such as the monitor or printer.
 
The Control unit endures that the other components are performing their tasks correctly.
