A computer is a smart machine, but it cannot talk or show results on its own. It needs output devices to share information with users. Output devices of computer help us see, hear, or get printed results of the work done by the computer. Without output devices, a computer would not be useful for daily tasks.
In simple words, output devices show the final result of input and processing. These results can be text, images, sound, or videos. Output devices are used in homes, schools, offices, hospitals, and many other places.
In this article, you will learn about output devices of computer in easy English with clear examples.
What Are Output Devices?
Output devices are hardware components that receive data from the computer and present it in a form that humans can understand. The computer processes the data internally, and output devices display the final result.
For example:
- Typing a document → result shown on screen
- Playing a song → sound through speakers
- Printing a file → paper copy from printer
