Detailed explanation-1: -A touch screen monitor is used to input and receive information from a single peripheral device, usually a laptop touch screen monitor. So, when using a touch screen monitor, users do not have to use a keyboard or mouse. They can quickly input data directly into the device by touching the screen.
