In master-slave architecture, a device that operates under the control of another (the master) is called a slave device.

In older versions of Microsoft Office, the Office Assistant (like Clippy) would display a yellow light bulb icon to indicate that a new tip or suggestion was available.

A teleprocessing terminal acts as an input/output device that allows users to enter data into a remote computer system.

A writing tablet, or digitizer, is an input device that allows users to hand-draw images or write text, which is then converted into digital data. Other options like mice or touch panels do not primarily serve the function of converting handwritten impressions into specific positional coordinates.

An off-line device is one that is not currently connected to or under the direct control of the CPU. This is the opposite of an on-line device, which is actively communicating with the processor.

Screen resolution is defined by the number of pixels displayed horizontally and vertically on the screen.

Menu interfaces are ideal for users who are not familiar with complex command-line syntax, as they provide a visual list of available options, reducing the memory load.

MICR (Magnetic Ink Character Recognition) is the technology specifically used for reading characters printed with magnetic ink, commonly found on bank cheques. Other options like VDU, Keyboard, or OCER do not serve this specific purpose for cheque processing.

The cursor is the visual indicator on a screen that shows where the next character or action will occur.

Webcam is an input device.

Dumb terminal is an output device. It stores the data received from the CPU, but does not process it.

A microphone is the input device used to capture audio or voice commands to communicate with a computer.
