Potential for a much higher data transfer rate than USB-A. A 100-watt, 20-volt connection is far more powerful than the older port and can handily power even larger devices. A slimmer design that fits into a port no matter which direction it’s flipped, designed to replace A, B, mini, and micro USB connections all at once. Designed to solve many of the old USB-A port problems, USB-C was an entirely new type of USB port. USB-C is a newer port type officially announced in 2014, although it took several years for the ports to reach widespread consumer devices, as we see today. Note that there are also subsets of this design, like USB Mini-A and USB Micro-A, with different port designs, but these aren’t as important for our current discussion. There are USB-B to USB-B cables, but they’re rarely used. USB type B is mainly for external peripherals, with a USB-A connection on one end and a USB-B connection. 
Type B connections also are easy to recognize because of their square shape with rounded corners on one side, almost like the shape of a tiny house. The USB-B connector is the receptor port on the USB device you are connecting to the host computer. Interestingly, there is no USB-B host port.
