An output device is any peripheral that receives data from a computer, usually for display, projection, or physical reproduction. For example, the image shows an inkjet printer, an output device that can make a hard copy of any information shown on your monitor, which is another example of an output device. Monitors and printers are two of the most common output devices used with a computer.

What are the output devices of my computer
Every computer has a monitor or display screen, a sound card (or on-board sound on the motherboard), and a video card (or on-board video on the motherboard), which are all output devices. A printer is also very commonly used with computers. Depending on the type of computer and how the computer is used, other output devices may be used with a computer. The best method of determining all of the output devices your computer has is to go through the list above.
Why do computers need output devices?
A computer can still work without an output device. However, without an output device, you'd have no way of determining what the computer is doing, if there are errors, or if it needs additional input. For example, you can disconnect your monitor from your computer, and it will still function, but it's not going to be very useful.
