USB-C describes the connector itself, the rounded rectangle or oval shape with 24 pins on the inside. One of the best features of USB-C over its predecessors is that the plug is reversible, meaning you never have to worry about plugging it in upside down.

The pin layout is 3 times what was available on even the later generation USB 3. There are three primary pieces to the layout with one supporting the old USB 2. As I said at the outset, part of what is so compelling about USB-C is that it can take the place of so many other ports. It was a bit of a pain point for early adopters as laptop manufacturers began replacing legacy ports with USB-C, forcing people to carry dongles or docks to fill the void.
However, this is becoming less and less of a concern with more USB-C friendly products. Using compatible cables and devices, you can expect up to 4K at 60 frames per second to two monitors or 5K at 60fps to a single monitor.

It was in direct response to devices dropping the traditional headphone jack and offered standardization around an existing port along with new features like hotword detection and support for noise cancellation.
Not only is USB-C able to supply considerably more power than its predecessors, but it can do so while still transferring data at high speeds over the same cable. Another useful feature with some USB-C devices is bidirectional charging, which allows one device to charge another. An easy example is the Samsung Galaxy Note 10 Plus charging another smartphone.

Similarly thanks to the up to 40Gbps data transfer speeds possible via USB-C you can plug in an external hard drive to vastly expand your storage and see speeds comparable to your internal drive. This protocol has been around since and most will associate it with the familiar and still ubiquitous rectangular USB-A ports or the smaller micro USB ports.
This can cap your data transfer speeds, maxing out at Mbps. Additionally charging speeds will be slower with 5 volts at 0. That makes them less than ideal for charging devices like a modern flagship smartphone and virtually useless for charging a laptop. This is where things get a little confusing as this was originally known as USB 3. Similar story here on the naming, this was previously known as USB 3.
As the more consumer-friendly name suggests this protocol doubles the speed from its predecessor with a max of 10Gbps.

Only one previous name this time, USB 3. Predictably that leads to another speed doubling at up to 20Gbps. We also finally see the same bump on the power front with 5 volts at 3 amps with a maximum output of 15 watts. We expect to see USB4 products sometime in and the headline feature is another data transfer speed doubling with up to 40Gbps. Similarly, USB4 will include USB Power Delivery by default, which can dramatically boost device charging speeds and is inconsistently implemented currently.
For every generation prior to USB4, USB Power Delivery is distinct from the USB protocol, but it has a major impact on device charging with the ability to support 20 volts at 5 amps and a maximum output of watts. It also can optimize power management so that the correct wattager is delivered to one or multiple connected devices. USB-C monitors supporting Power Delivery can provide a charge to the laptop via the same cable that is carrying the image.
Notably, the latest version of Quick Charge 4. Thunderbolt 3 is capable of the same 40Gbps data transfer that we will see from USB4 starting in , allowing for the use of external GPUs, 4K 60fps video on dual-screens, 5K 60fps on a single screen, and daisy-chaining of devices like multiple external hard drives.
