Correct answer is (a), touch screen:
A touch screen is a computer display screen that is also an input device.
The screens are sensitive to pressure; a user interacts with the computer by touching pictures or words on the screen.
There are three types:
1) Resistive:
A resistive touch screen panel is coated with a thin metallic electrically conductive and resistive layer that causes a change in the electrical current which is registered as a touch event and sent to the controller for processing.
2) Surface wave:
Surface wave technology uses ultrasonic waves that pass over the touch screen panel.
When the panel is touched, a portion of the wave is absorbed.
This change in the ultrasonic waves registers the position of the touch event and sends this information to the controller for processing.
3) Capacitive:
A capacitive touch screen panel is coated with a material that stores electrical charges.
When the panel is touched, a small amount of charge is drawn to the point of contact.
Circuits located at each corner of the panel measure the charge and send the information to the controller for processing.
