Computer Systems

1. Input

   • Keyboard- Allows the user to enter data by processing keys
   • Mouse-Allows the user to access data by processing clicks
   • Touch Screen-Allows the user to control and access the device by reconising finger movements
   • Microphone-Picks up sound and converts it into input data which can be accessed by the computer system
   • Heat Sensor-Detects the surronding temperature and produces input data accordingly

2. Output

   • Moniter-Allows the user to visually see the data they are accessing by processing output data from a processing device
   • Printer-Allows the user to print documents they have created virtually on to paper by accessing output data
   • Speaker-Allows the user to listen to audio data such as music and podcasts by accessing output data created by a processor
   • Projector-Allows the user to project the image on their moniter onto a larger surface by accessing the same output data as the moniter
   • Plotters-Allows the user to create large, high quality drawings (much like a printer) by reading output data
