Definition Input Devices
An input device is a piece of hardware that allows a user to send data and control signals to a computer or information processing system. It acts as a way for users to communicate with a computer, providing it with the information it needs to perform tasks. Common examples include keyboards, mice, scanners, and microphones.

Examples of input devices
• Keyboard: Used to type text and commands into a computer.
• Mouse: A pointing device used to control the cursor on a screen, with features like clicking and dragging.
• Microphone: Converts sound waves into electrical signals, allowing you to input audio for recordings, calls, or voice commands.
• Scanner: Converts documents or images into a digital format.

Definition Output Devices
An output device is a piece of computer hardware that converts processed data from a computer into a human-readable format, such as text, images, sound, or a physical copy. It is how a computer communicates the results of its processing back to the user, taking information from the machine's language and presenting it in a way that humans can understand.

Examples of output devices
• Monitors: Display visual output like text, images, and video.
• Printers: Create a physical copy of digital documents or images on paper.
• Speakers and headphones: Produce audio output, such as music or sound effects.
• Projectors: Project computer-generated images onto a surface, like a screen or wall, often used for presentations.
