Input and Output Devices

Input and output devices allow the computer system to interact with the outside world by moving data into and out of the system. An input device is used to bring data into the system. Some input devices are:

  • Keyboard
  • Mouse
  • Microphone
  • Bar code reader
  • Graphics tablet

An output device is used to send data out of the system. Some output devices are:

  • Monitor
  • Printer
  • Speaker

A network interface acts as both input and output. Data flows from the network into the computer, and out of the computer into the network.

QUESTION 8:

Do you think that data transfer from the network is slower or faster than from main memory?
