A Field Guide to the Cables Around the Office

A Field Guide to the Cables Around the Office

If there’s one thing you likely have plenty of in your office, it’s cables. Each device you regularly use probably has compatibility with at least one kind of cable… but can you identify them and what they do? Below, we’ll go over a few common cable types so that you’ll be able to do just that.

USB Cable Types

The Universal Serial Bus cable connection is the most common around the world, as most accessories and peripherals leverage the USB port. There are also many different versions of USB technology, each supported by different shaped connections.

Type A connections support USB 1.0, USB 2.0, USB 3.0, and USB 3.1, with transmit speeds ranging from 1.5 MB/s to 1.25 GB/s. These are the connections that are found on at least one end of every USB cable nowadays.

Type B connections also support USB 1.0, USB 2.0, USB 3.0, and USB 3.1. Far less common than other USB connections, they were once used primarily to connect a printer or similar device to a computer. While still utilized, they are slowly being phased out.Mini and Micro both support USB 2.0.

Micro-USB, which in turn is being phased out by Type C connections.


 Type C connections (also known as USB-C) support USB 3.1, USB 3.2, and the upcoming USB 4 standard. Moving forward, it is very likely that the USB-C connection will be increasingly popular. This is because USB 4 will use this connection type, and in addition to being backwards-compatible with all generations of USB, it can support much faster data transfers.


Display Cables

VGA Cables

 One of the oldest computer monitor cables, Video Graphics Array cables have become less popular as its analog video signal has been abandoned in favor of digital. Nevertheless, there is likely to be a VGA port on your video card or display.


DVI Cables

 At the turn of the century, VGA cables were more or less phased out by Digital Visual Interface cables. These connections came in various types, each with their own capabilities. Nowadays, DVI has itself been replaced by modern display cable types.


DisplayPort Cables

 DisplayPort cables were designed to replace VGA and DVI cables, transmitting both video and audio signals. There are many versions of DisplayPort out there, all compatible with each other, and DisplayPort can also be used with HDMI and USB if an adapter is leveraged. Today, it is most commonly used to attach a monitor to another device.


HDMI Cables

 The High-Definition Multimedia Interface cable is the modern standard for digital signals, with five different types of HDMI connections existing today. Chances are, you’re most familiar with Type A, although you may have seen Type C in the context of a digital camera, or Type D in the context of a mobile device.


Networking Cables


 Serial Advanced Technology Attachment cables form the connection between a storage device and a computer’s motherboard. They offer faster data transfer speeds as compared to their predecessor, the IDE (Integrated Drive Electronics) cable.

 If you have a local area network, you’re using ethernet cables. These are the cables that connect your router to your modem and/or computer. They are quite easy to distinguish from other cables, as they have a very particular appearance.
