What is a USB Cable?

We know that technology evolves faster and further every day and it can sometimes feel overwhelming. That’s why we’ve partnered with StarTech.com, a global leader in manufacturing top-quality USB cables and connectivity solutions, to bring you this USB Cable Guide.

Here, you’ll learn everything you need to know about the various types of USB cables, what the USB versions mean for transferring your data, and how they work.

USB stands for Universal Serial Bus and is an umbrella term used to describe the most common port type: the rectangular USB, known as USB A. Typically, USB ports are found across multiple devices, such as phones, PCs, and gaming consoles.

Initially developed in the mid-90s, the USB connection was created to standardize ports for peripherals. This is so secondary devices, like printers and keyboards, can connect to a wider range of computers and hosts, rather than a select few with specific receptacles.

Today, there are a variety of USB types, but the main use of all USBs has remained the same: to transfer data and power. Over time, new versions have been released to improve transfer speeds and power output.

StarTech.com are the experts when it comes to how this technology works. The industry leaders explain a USB 2.0 cable connection like this:

“If you were to open up a USB cable, you would notice 4 different USB wire colours: white and green, which carry data, and red and black, which are used for power. Red carries 5 volts and acts as the positive wire, while black is the negative wire, otherwise known as the ground wire.
