Today, most homes have a multitude of electrical devices and technology is ever-changing, it is no surprise that many people complain that there are too many cables and wires to keep a track of. The image of a drawer, box or cupboard filled with haphazard electric cables is all too common to many of us. For many, the USB port has become a household name for electrical devices, but many have no idea about the varieties of USB connectors and cables and the significance they bring.

Data Cable Connector or a USB connector is the physical connecting point from a USB cable to a USB port. A USB connector enables for a stable and properly connected USB. One way it does this is by guaranteeing that only a specific type of USB cable can be connected to a specific USB port. Without the appropriate connector, there would be much higher cases of users attempting to connect the wrong cables into USB ports.

Common types of data cables and connectors

Type-A: The standard flat, rectangular interface that you find on one end of almost every USB cable. Most computers ...
... have multiple USB-A ports for connecting peripherals. You will find them on game consoles, TVs, and other devices too. This cable only inserts in a way.

Type-B: An almost-square connector, mostly used for printers and other powered devices that join to a computer. They are not very common these days, as most devices have moved onto a smaller connection.

Mini-USB: A smaller connector type that was standard for mobile devices a while back. While not that common these days, you will still see these on some devices, which are typically from Sony. These include cameras, MP3 players, the PlayStation 3 controller, and similar.

Micro-USB: Another past standard, gradually declining in popularity, for mobile and portable devices. It is even smaller than a mini-USB. While you will still find micro-USB on some tablets, smartphones, USB battery packs, and game controllers, several have moved onto USB-C.

Type-C: This is the most recent type of USB cable. It is a reversible connection that packs higher transfer rates and more power than earlier USB types. It is also able to juggle multiple functions. You will see it on numerous modern laptops and smartphones, including Pixel phones, MacBooks, and controllers for the PlayStation 5 and Xbox Series S|X.

Lightning: This is not a true USB standard, but is Apple's proprietary connector for the iPhone, AirPods, some iPad models, and more. It is a similar size to USB-C and comes normal on most Apple devices released since September 2012. Older Apple devices use the much larger 30-pin proprietary connector, and newer iPad Pro models use USB-C.

In maximum cases, you will find USB cables have one standard type-A end and one type-B end of some sort. The type-A end powers the device, while the type-B end gets power. This is to stop prospective damage that would be caused by connecting two computers via USB-A.
