You frantically search through your cupboards, drawers and bags, untangling the wires as you go. The reality is that not all USB cables are created equal. While you might not have realized it, you probably found USB 2. So how can you tell the difference and learn which cables connect to what? First things first, there are two different type of connectors: male and female. This applies to all cables, as well as other connectors and fasteners. The male connector fits inside the device.
Understanding USB means knowing the difference between types and versions, and how these influence which connectors and cables you use. The technology that allows data to be transferred along a cable from one device to another. Although a cable has two differently shaped connectors, it takes the name of whichever connector is not USB Type-A. If the cable has a Type-A connector at one end as in the above image , that will usually be the first type. The second will be the shape of connector that will plug into your device.

USB 3. In , a new standard, USB 3. Developed in the s, the Universal Serial Bus USB standard was developed to define communication protocols, including cables and connectors, between computers and electronic devices such as printers and scanners. As the number of devices multiplied in quantity and types, the USB port was adopted as the basic connection portal. Devices like smartphones, PDAs, tablets, smartphones and video game consoles can connect to computers with USB ports allowing recharging and communication thereby replacing the requirement of adapters and power chargers.
It preserves existing USB 3. Earlier USB concepts such as endpoints and the four transfer types bulk, control, isochronous and interrupt are preserved but the protocol and electrical interface are different. The changes in this specification make improvements in the following areas:. The structural topology is the same, consisting of a tiered star topology with a root hub at level 0 and hubs at lower levels to provide bus connectivity to devices. The SuperSpeed transaction is initiated by a host request, followed by a response from the device.
Confused about the difference between USB 2. Know which is suited for your needs by learning all about the differences of each here. There are six main differences between the universal serial bus USB 2. Not only is there a difference in size, but also a handful of others like transfer rate and bandwidth to name a few that distinguish the different USB versions. Before developers even invented USBs, computers had already utilized parallel and serial ports to transfer data.
USB 3. This new standard offers increased transfer rates up to 4. Implementation of the technology began in initially with USB 3. Hubs followed allowing additional 3.
