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 [url=http://www.china-

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.

Each type of USB connection (USB cable type A, B, C, micro and 

mini) has a pinout system, these are the small metal strips inside 

the connector, designed to access each of these wires and their 

capabilities.”

Over the last 25 years, there have been several different USB 

cables and iterations, depending on the USB protocol. The USB 

started with version 1.0, which transfers up to 12Mbps and was 

released in 1995. The latest today is USB version 4, which 

transfers up to a massive 40Gbps.

StarTech.com know that users want the best USB for the job, which 

is why they have created a table below to help decipher the speed 

and capabilities of each version.
