Computer Science - Paper one
Von Neumann Architecture
Architecture
components that exist in an computer system
All components interconnected
There are many different architectures all with different arrangements of components
Sub-Components of CPU
Control Unit
Arithmetic Logic Unit (ALU)
Memory Unit
What These Sub Components D
Control Unit
Responsible for coordinating activity of other components
Program Instructions may require data to be Input, Output or Stored
Interprets Instructions
Manages The Computers Response
Arithmetic Logic Unit
Perfroms Arithmetic and logic Operations as well as performing comparisons
This helps the computer perform a limitless number of tasks
Registers
Small but very high speed storage area
There are many registers
These many registers contribute to execute instructions performed upon data
Memory
All of these are connected by bus
other buses are used to connect Input, Output and Secondary Storage Devices
THESE ARE NOT APART OF THE VON NEUMANN ARCHITECTURE
