I want to know the correct definition of an input and output device for GCSE ICT.

An input device is a device which is used to input (enter) data into a computer system for processing. Input devices can be manual, where data is entered by hand, e.g. keyboards, mice, scanners and microphones, or automated, where data is entered automatically without human intervention, e.g. sensors, optical mark readers, and bar code scanners.

An output device is a device which displays the results of the processing done by the computer system, using formats such as printed pages, sound and video. The most common output devices are printers, monitors, and speakers.
