![]() ![]() Most USB cables, outside of the latest USB-C cables, have a USB-A connector on one end, and an alternative USB connector on the other that is more specific to the device they’re connecting to. Type-A connectors were used for USB 1.0, 1,1, and 2.0 specifications, delivering up to 480Mbps of data transfer rate at the revised 2.0 standard, and as little as just 1.5Mbps in its very first iteration.Īlthough USB-A connectors are far from the only USB connector type, they did end up being the connector type for many devices, even with the advent of newer options. It’s a rectangular connector with four pins in older generations, and nine pins in newer, faster versions. The first, original, and most well-known type of USB connector is USB-A. Never fear, though, Cable Matters is here to explain everything. ![]() There are also mini and micro versions of certain cables, and multiple generations of them – which makes it all a little confusing. USB connector types come in a range of shapes and sizes, with most given some form of letter denomination to differentiate them from the alternatives. However, the latest generations of Thunderbolt technology are more capable in some respects, with stricter standards. Thunderbolt technology, developed by Intel and Apple, has moved from using a Mini DisplayPort connection to leveraging the USB-C cable type and protocol. It’s likely that USB-C connectors will replace Apple’s iconic Lightning charging connector in the years to come, too (in the meantime you can just use a lightning-to-USB cable ).Īlthough USB itself is the most popular cable standard among consumer electronics, it does have modern competition, too. Over the years, however, USB has competed with, and ultimately supplanted many other cable and connector designs, including Firewire, MIDI, and PS/2, as they simply weren’t as convenient, as fast, or as versatile. When it first launched, USB connectors and USB cables replaced legacy connectors like serial and parallel ports which were not only large and bulky, but antiquated in their capabilities. There are also different features on different USB connectors and cables, such as supporting different video transmission resolutions and refresh rates. They provide very different capabilities, from transfer rates to the amount of power they can transmit for charging or powering a device. Since then, however, USB connectors have been developed into all sorts of different shapes, sizes, and abilities, with massive improvements in their ability to handle more complicated data and much faster speeds.Īlthough many modern USB devices now use USB-C connectors or some variation of them, there is a wide range of legacy USB connectors and cables which can still be found in use today. ![]() The first USB connectors launched in 1996 with the standard USB Type-A connector, offering a modest 1.5 Mbps transfer speed and few additional features. That’s all thanks to their ability to transfer data, transmit video, and provide charging and power capabilities, all in a single cable. Today, USB connectors can be found on almost any electronic device, including smartphones, laptops, throwaway gadgets, and everything in between. It was designed to standardize and modernize the way peripherals and accessories connect to desktop and laptop computers, but it has become much more than that over the years. The humble Universal Serial Bus connector, or USB, is the most prolific data transfer medium the world or consumer devices has ever seen.
