Answer Details
(a) The completed table:
| Device | Input or Output | Purpose |
|---|---|---|
| Microphone | Input | Captures the teacher's voice for recording lessons or for use in video conferencing, converting sound waves into electrical signals the computer can process. [1] |
| Projector | Output | Displays images, videos or presentations from a computer onto a large screen or wall so the whole class can see the content. [1] |
| Scanner | Input | Converts printed documents or images into digital files that can be stored, edited or shared on the computer. [1] |
A microphone is an input device because it sends data into the computer. A projector is an output device because it receives data from the computer and presents it visually. A scanner is an input device because it captures external data (a printed page) and digitises it for the computer to use.
