The computer’s output is just as important as the input. In this video, you’ll learn about printers, speakers, and display devices.

When we put information into a computer, we’re usually performing some type of action on that information. And then we need to get it out of the computer. In this video, we’ll look at some common PC output devices.

If you want to get information out of your computer and onto a piece of paper, you’re going to need a printer. There are color and black and white printers. And you can often find printers to not only print your documents, but your pictures as well.

There are many different ways to connect and output information to these printers. One is through a direct connection with USB, although we’re seeing more network connections with Ethernet and 802.11 wireless. If you want to use a personal area network, you might want to consider getting a printer that can support infrared or Bluetooth connectivity.

Our streaming audio and video services wouldn’t be very good unless we could hear what was going on. One way to do this is by using speakers. Speakers will output information in an analog form, so that we’re able to hear it with the human ear. The speakers are usually connecting to our computer through a TRS Jack. TRS stands for Tip/Ring/Sleeve, and these jacks are usually labeled with ‘speaker output’ or ‘audio adapter’

One of the most popular output devices is the monitor. It’s the screen that we see right in front of us. This is how our human eyes are able to see what’s happening inside of this computer. There are a number of different ways to connect a display device to our computer, so many that we have a dedicated video just on display device connectivity. There are also many different sizes of display devices. You can find them in many different dimensions and resolutions.
