Buttons and Ports on a Computer

Buttons and ports on computer

Take a look at the front and back of your computer case and count the number of buttons, ports, and slots you see. Now look at your monitor and count any you find there. You probably counted at least 10, and maybe a lot more.

Each computer is different, so the buttons, ports, and sockets will vary from computer to computer. However, there are certain ones you can expect to find on most desktop computers. Learning how these ports are used will help whenever you need to connect something to your computer, like a new printer, keyboard, or mouse.

Back of a computer case

The back of a computer case has connection ports that are made to fit specific devices. The placement will vary from computer to computer, and many companies have their own special connectors for specific devices. Some of the ports may be color coded to help you determine which port is used with a particular device.

Setting up a computer

So you have a new computer and you're ready to set it up. This may seem like an overwhelming and complicated task, but it's actually a lot easier than you might think! Most computers are set up in a similar way, so it doesn't matter what brand of computer you have.

If you're setting up a new computer that's still in the box, you'll probably find a how-to guide that includes step-by-step details. Even if it didn't include instructions, you can still set up the computer in a few easy steps. We'll take you through the different steps needed to set up a typical computer.

Step 1

Unpack the monitor and computer case from the box. Remove any plastic covering or protective tape. Place the monitor and computer case on a desk or work area.

Be sure to place your computer case in an area that is well ventilated and has good air flow. This will help to prevent the computer from overheating.

Step 2

Locate the monitor cable. There are several types of monitor cables, so the one for your computer may not look like the one in the image below.

If you're having trouble finding your monitor cable, refer to the instruction manual for your computer.

Step 3

Connect one end of the cable to the monitor port on the back of the computer case and the other end to the monitor. If you're using a VGA cable like the one in the picture below, you'll want to tighten the screws on the monitor cable to secure it.

Many computer cables will only fit a specific way. If the cable doesn't fit, don't force it or you might damage the connectors. Make sure the plug aligns with the port, then connect it.
