_______ is the standard input and output device which both receives information and displays it as well. It eliminates the use of a keyboard or a mouse.

Correct option is C

The correct answer is (c) Touch screen.
Explanation:
● A touch screen is a unique hardware component that functions as both an input and an output device.
● It receives input by sensing the touch of a finger or stylus and simultaneously displays the visual output on the same interface.
● By allowing direct interaction with the display, it removes the necessity for external peripherals like a physical keyboard or a mouse.
Information Booster:
● Modern smartphones and tablets almost exclusively use capacitive touch screens for high sensitivity.
● ATMs often use resistive touch screens which can be operated with gloves or a fingernail.
● Direct manipulation of the GUI (Graphical User Interface) via touch makes computing more accessible to non-technical users.
Additional Knowledge:
● Trackball – An input device consisting of a ball held by a socket containing sensors to detect a rotation of the ball about two axes.
● Touchpad – A specialized surface that can translate the motion and position of a user's fingers to a relative position on the operating system.
