1. Input and Output Devices of a
Computer
• Understanding how computers interact with the world
• Presented by Greeshma

2. Introduction
• Computers need devices to interact with users and the outside world.
• • Input Devices: Help us give data and commands to the computer.
• • Output Devices: Show us the results of the computer’s work.

3. What Are Input Devices?
• Input devices are tools we use to send data into a computer.
• They convert our actions, voice, or documents into digital signals the
computer can understand.

4. Examples of Input Devices
• • Keyboard – Used for typing text, commands, and numbers.
• • Mouse – Moves the pointer and selects items on the screen.
• • Microphone – Captures voice and sound input.
• • Scanner – Converts physical documents into digital format.
• • Webcam – Takes photos or records videos.

5. What Are Output Devices?
• Output devices present the results of computer processing.
• They help users receive information in a visual, printed, or audio form.

6. Examples of Output Devices
• • Monitor – Displays text, images, videos, and graphics.
• • Printer – Produces printed copies of digital work.
• • Speakers – Play audio from videos, music, or alerts.
• • Projector – Projects the computer screen onto a large surface.

7. Devices That Are Both Input and
Output
• Some devices perform both input and output functions:
• • Touchscreen – Accepts input by touch and displays output.
• • External Drives – Read and write data to and from the computer.
• • Network Cards – Send and receive data over networks.

8. Importance of I/O Devices
• • They enable communication between us and the computer.
• • Without them, computers would be difficult to use.
• • They allow us to work, create, play, and interact with digital technology.

9. Summary
• • Input Devices send data to the computer (e.g., keyboard, mouse).
• • Output Devices receive and present data from the computer (e.g.,
monitor, printer).
• • Some devices do both jobs!
• I/O devices are essential to all modern computing.
