Touch screen monitors join both an input and output machine, minimizing the require for divide peripherals like keyboard, mouse and monitor. Instead a user just has to touch the monitor with also a finger or from time to time a stylus at manipulate the graphical user interface.

Touch screen monitors use one of a number of technological systems to be familiar with a person's touch the most common being resistive, capacitive, infrared and acoustic wave. Resistive touch screens are the most versatile, they consist of a normal glass plate that is covered with both a conductive and a resistive metallic layers.

The two layers are spaced apart and an electrical current runs through them while the monitor is running. When a user touches the screen, the layers make contact in that exact spot causing interference in the electrical field, the computer then calculates the coordinates.
