Unit 1.1 System Architecture

1. "Computer parts"

   • Memory;Ram/Rom—stores all of the memory permanently or temporarily.
   • Secondary storage;SSD or Hard drives—storage that isn’t being used internal or externally.
   • CPU;(central processing unit) where the calculations of the computer take place “the brain”.
   • Network card;it makes a computer able to connect to a network.
   • Graphics Card;(GPU) outputs an image onto the screen.
   • Motherboard;where all the different components link together.

2. Von Neumann Architecture

   • Memory; The memory is used to store currently being used data an example of this is RAM & or ROM.
   • (Data and Addresses are transferred to the CPU using then data and address busses.)
   • MDR--Memory Data Register. (Stores data for CPU)
   • MAR--Memory Address Register. (Stores addresses of data for CPU)
   • ALU-- (Arithmetic & Logic Unit) Calculate arithmetic and logic operations.
