Answer
Brief Explanations:
- A keyboard is an input device mainly used for typing words and numbers into a computer or other electronic device. Printing is done by a printer, scanning by a scanner, and moving the cursor is mainly the mouse's function.
- The primary function of a mouse is to direct the cursor on the screen, allowing users to interact with graphical - user interfaces. Scanning is not its function, data processing is done by the computer's CPU, and typing is for the keyboard.
- A monitor is an output device that displays visual information such as images, videos, and text from a computer or other source. It is not an input device, power supply unit, or storage device.
- A printer is a device that produces physical copies of digital data like documents, images, etc. Producing digital copies of physical data is for a scanner, data processing is for the CPU, and displaying visual information is for a monitor.
Answer:
- Typing words and numbers
- Directing the cursor on the screen
- An output device that displays visual information
- A device that produces physical copies of digital data
