Network Card, Graphic Card and Sound Card

•A Network Interface Card is an electronic device that allows you to be able to connect your computer to a computer network.

•A graphics card uses binary data which then makes a 3-D image. This works how a CPU would work by sending out a signal to then create the images.

•A sound card is an expansion card so that you are able to produce sound from your computer but not every computer comes with one but can still work without one.
