computer cable

Hooking up a computer monitor is not terribly complicated but there are a few different types of cables that can be used to get the job done. Before even purchasing a monitor, start by checking the computer itself. Look at the back to the machine to see what kind of video ports are on there. Ideally, you will want the same type of connection on the monitor and computer. If you find yourself with a mismatching monitor and computer, you can use an adapter or converter to change one type of connection to another.

When making your selection, there are five main types of connections built onto modern monitors: VGA, DVI, HDMI, DisplayPort, and USB.

VGA

VGA (also called HD15) is an older type of video-only connection. Many used or outdated monitors will have this type of connection while newer models probably will not. VGA is the old standard for monitors and has since been replaced with newer formats. Out of all the monitor connections still in use today, VGA is the only one that is purely analog. This means VGA has a maximum resolution of 640 x 480, a far cry from the 1080p quality available with digital connections. Generally, users only want to use VGA if any of the newer, digital options are not available.

DVI

Most devices that use USB cables come with one, but these prepackaged cables tend to be too short. Few things are as annoying as having to leave your device in a weird spot to recharge or trying to keep your phone charger from falling off the table. Using USB extension cords to get a little extra distance can be convenient or outright necessary in these situations.

There are a few facts to keep in mind when it comes to USB extension cables. First off, make sure you are picking out the correct type of extension cable. The average USB extension cord is going to be USB 2.0 A Male to Female. Some other types do exist, such as the USB 3.0 A to B male cable, but typically “USB extension” means an A Male to Female cable.

Another other key detail to check is whether you need a USB 2.0 or 3.0 extension. Usually, the plastic inside the metal end of the USB cable will be color-coded, with 2.0 cables being black or white and 3.0 cables being blue. Not every manufacturer does this, so it never hurts to double-check your cable beforehand. You can use 2.0 extensions with other 3.0 cables, but you will only get USB 2.0 data and recharging speeds. If you want 3.0 speeds, every piece of equipment you are using must be 3.0 rated.

Computer cables (data cables) are somewhat similar to audio and video cables. Instead of transmitting sound or images, they send data for your computer to use. This can be anything from sending over a Word document to streaming movies and TV shows. Technically Ethernet cables fall under this category, but Ethernet is such a broad topic it needed its own independent article. Common types of computer cables include:

• USB
• FireWire
• Serial
• DIN
• PS/2

USB

USB is the most common type of computer cable today, being found on computers, printers, hard drives, cell phones, and more. Along with transmitting data, USB is commonly used to recharge batteries on cell phones and other devices like video game controllers. There are several types of USB cables in various shapes and sizes. The two primary groups are USB 2.0 and USB 3.0.

USB 2.0 is capable of speeds up to 480 Mbps and comes in a few different varieties. When someone just says “USB”, they are generally referring to USB 2.0 Type A. These are the standard rectangle-shaped connections you can find on any computer. Next, there is Type B, which is also called a printer cable. And then there is the USB 2.0
