Input and output (I/O) devices are components that allow users to interact with a computer system. Input devices are used to send data or signals to the computer. Common examples include keyboards, mice, scanners, microphones, and webcams. These tools let you enter information—like typing commands, recording audio, or uploading images and text.
Output devices take data from the computer and present it in a form we can understand. Monitors display visuals, printers produce physical copies, and speakers or headphones output sound. Essentially, input devices feed information into the computer, while output devices deliver results out of it.
Some devices serve as both input and output. These are known as I/O devices. Examples include touchscreens, which allow you to tap (input) and view graphics (output), and headsets, which combine microphones and speakers for real-time interaction.
Understanding the distinction between input and output devices helps clarify how computers process and communicate data. Whether you’re clicking a mouse or watching a video on your screen, these tools allow us to interact with our technology to accomplish the desired result.
