USB cables have different types and connectors, each designed for specific purposes and device compatibility. The main difference between older and newer USB generations is the speed at which they can transfer data between one device and another.

Programming and Debugging: USB cables are essential for programming and debugging certain electronic devices. A USB connector is the socket, port, or jack into which the plug end of a USB cable or USB-powered device is inserted. This is because you will always need two components of opposite genders to couple together to form the connection, regardless of what type you are using. You plug the Type-B connector into the printer, scanner or other device and the Type A connector into the standard USB port on your computer. Compared to Type A, the USB Type B connectors are square with a slight rounding or large square protrusion on the top.Although USB Type A is still the most used connector, the USB Type C are becoming increasingly more popular.

In a standard USB C cable, there are Type C connectors on both sides, and have been adopted by various smartphone companies.Extend the reach of your Micro USB port and provide extra room for charging or connecting peripherals to your smartphone or tablet. If the cable has a Type-A connector at one end (as in the above image), that will usually be the first type. Female USB connectors allow the male part of a USB cable or plug to be inserted into any compatible device.
