Its symmetrical design allows it to be inserted in the receptacle in either fashion, so you never have to try again (one of the biggest peeves about earlier USB plugs). This latest USB connector has finally solved the problem of which side goes up. Only USB 3.1 Type C plugs and receptacles (and thus cables) exist, but adapters for backward compatibility with USB 3.0 and 2.0 connectors are available.

USB Type C: Often referred to simply as USB-C, these plugs and receptacles are rectangular with four rounded corners.

The female connector on the device, computer, or extension cable is typically called the receptacle. If you get 200mbps or more, you should be jumping from joy.The male connector on the cable or flash drive is typically called the plug. In the wi-fi world, the marketing can say they sell you a "gigabit ac1750 router (or adapter)", and in real life you may well end up with just 100Mbps or slower data throughput. Wireless is not like wired Ethernet, where saying 100Mbps really means that you will actually see TCP/IP data transferred nearly at that rate.

You see, the wireless data transfer rates are basically a big marketing scam because half of more of that data transfer rate will disappear due to weakening signal with distance or on the physical layer chatter. In other words, a lot less than USB2 can handle. At TCP/IP level, the throughput will be much lower, even if the distance is short, somewhere in the neighborhood of 100-300mbps, depending on your luck. However, much of that number pertains to the "physical layer" information transfer, the chatter that ensures that your data is transferred accurately, under optimal condition (e.g.

Let's say we're talking about a two stream AC device, so theoretically it's capable of 867mbps throughput in 5GHz band. You think you need USB3 to drive a 802.11ac network adapter at full speed? Please.
