Computer

A computer consists of 2 sections:

Data is transmitted between the two sections accordingly.

The left is the von Neumann architecture (called such because it was first defined by John von Neumann in 1945)

Motherboard

The motherboard in a computer acts like its heart.

  • CPU and memory are inter-connected by the system bus made up of 3 buses (address bus, data bus and control bus)
  • Bus inside a computer = a group of electrical wires that are used to transmit similar information
    • transmit the ID information of a device
      (= address/identifier)
    • transmit information between devices
      (= data/information)
    • transmit commands to devices
      (= control/command)

Peripheral devices (a.k.a.: Input/Output (I/O) peripheral devices)  

  1. Input devices (e.g., mouse, key board, scanner, disks…)
    1. Enables human users to enter data into the computer (= machine)
    2. The data will be stored inside the computer in such a way that the computer can use it effectively
  2. Output devices (e.g., terminal, printer, disks, …)
    1. Enables the computer to show data stored inside the computer to a human user in a “humanly” way
  3. Peripheral devices are auxiliary devices that allow users to:
    1. Enter inputs into the computer
    2. Obtain outputs from the computer
