A printer is a peripheral which produces a text and graphics of documents stored in electronic form, usually on physical print media such as paper or transparencies. Many printers are primarily used as local peripherals, and are attached by a printer cable or, in most new printers, a USB cable to a computer which serves as a document source. Some printers, commonly known as network printers, have built-in network interfaces, typically wireless or Ethernet based, and can serve as a hard copy device for any user on the network.
Monitor
A computer monitor is an electronic device that shows pictures. A monitor is usually used to see programs on a computer. The main difference between a monitor and a television is that a monitor does not have a television tuner to change channels.

A monitor has a better display resolution than a television to make it easier to see smaller letters and graphics on.

The standard audio connection is a 3.5 mm stereo jack plug often color-coded lime green for computer sound cards.
