In almost every case, your PC is the host, and your smartphone, tablet, or camera is the device. In a USB network, there is one host and one device.
Separately from that, there's USB-C, which is a physical connection standard that devices can use. USB 1.0 is old enough that you'll virtually never see it, so USB2-USB4 covers the spectrum for most people. New Specifications There are now six USB specifications - USB 1.0, 2.0, 3.0, 3.1, 3.2, and USB4. It turns out there’s a method to all this madness - but first, we have to explain how USB power actually works. On some desktop PCs, even when they’re turned off, you can charge your smartphone via a USB socket. Sometimes, one USB socket on a laptop is seemingly more powerful than the other. You've probably noticed that some wall chargers are stronger than others. Not all USB chargers, connectors, and cables are born equal. Part of the reason for this problem is another feature that was buffed in USB-C to make it more effective and flexible: USB power delivery. Now you have to make sure you have the right cable for your gadget. Ten to 15 years ago, you always had to make sure you had the correct power supply for each of your gadgets. Instead of running around with a collection of manufacturer-specific wall plugs, customers with multiple USB-C devices have to run around with a manufacturer-specific or genuinely compatible third-party cable. But, in a brilliant example of getting exactly what we asked for and not at all what we wanted, USB-C has solved the wall-wart problem by transplanting it. USB-C is in the process of replacing them. The tech world has finally coalesced around a charging standard, after years of proprietary adapters and ugly wall-wart power supplies.
