What the ‘C’ in USB-C actually means (it is not what you suppose)

You seemingly work together with a USB port each day, whether or not you are plugging in your cellphone to cost or connecting a tool to your PC. In recent times, USB-C, also referred to as USB Kind-C, has change into the most typical kind of USB port, seen on most smartphones, laptops, tablets, gaming consoles, e-readers, and lots of different gadgets.

Within the cellular world, Android telephones have had USB-C for a very long time, however Apple lastly caught as much as the occasions and adopted USB-C on the iPhone again in 2023 with the iPhone 15 collection, lastly saying goodbye to its proprietary Lightning port.

I truthfully hadn’t thought a lot about USB-C recently as a result of it is change into so synonymous with all of the tech I exploit that I’ve simply grown used to it. Nevertheless, that modified lately when my pal, who purchased a brand new iPhone with USB-C for the primary time, requested me a easy but eye-opening query: “What is the C within the USB-C stand for?” It made me consider a humorous facet of know-how: regardless of its widespread use by tens of millions and even billions of individuals every day, many may not truly know what the ‘C’ in USB-C represents. And to be clear, I do not blame them.

As for what the reply is, in all equity, it is not the obvious. Once you take a look at a USB-C port or connector, it is not truly formed just like the letter C, so that is not the that means. My pal assumed it stood for connector, which is an affordable guess however not the reply both. To actually perceive the that means of the “C” in USB-C, it requires a little bit of exploration into the historical past of the USB port itself.

USB-C is the newest USB connector

It’s the successor to USB-A and USB-B

The explanation USB-C has its title is not as a result of the C stands for one thing like charging, cable, or connector. The C would not stand for a selected phrase, neither is it an acronym for something. The C in USB-C serves as an identifier for the design, because it’s the newest connector kind within the USB household, which incorporates two prior older design sorts: USB-A and USB-B.

The USB made its debut in 1996, when seven main tech corporations — Intel, Microsoft, IBM, Compaq, DEC, NEC, and Nortel — launched the Common Serial Bus (USB), a common connector for computer systems. USB was designed to make connecting peripherals like keyboards, mice, and printers to PCs simpler. Within the 25 years since its introduction, it has change into important to many technological improvements, together with smartphones, tablets, e-readers, and extra.

USB-A might be the USB port you are most accustomed to, because it’s the oblong connector that is been used on gadgets for properly over 20 years now, and continues to be generally seen at this time on USB flash drives, computer systems, gaming consoles, and extra. It is a thick connector, and given what number of laptops and tablets have been specializing in thinness in recent times, USB-C has largely taken over its place, due to its compactness and in addition its skill to deal with quicker information switch and charging speeds.

You could be much less accustomed to USB-B, a bulkier sq. connection sometimes seen on printers and exterior arduous drives. You might also discover USB-B ports on the again of screens, the place they function upstream ports, that means they ship information from the opposite USB ports in your monitor again to your PC. So in case you join a keyboard to your monitor’s USB-A port, you may must plug the USB-B port into your PC as properly, so it could possibly use it. Micro USB, which was on a number of smartphones again within the day, can also be a kind of USB-B port, it is only a miniaturized model.

That lands us on USB-C, the most recent kind of USB connector. Not like USB-A and USB-B, USB-C is a reversible connector with a symmetrical design, permitting it to be plugged in any orientation. Along with its user-friendly design, USB-C can also be rather more compact than USB-A and USB-B, that means it takes up method much less area on gadgets. In an age the place telephones just like the iPhone Air and the Galaxy Z Fold 7 exist, having a small but extraordinarily highly effective USB port is integral to retaining the gadgets skinny and lightweight.

So, to recap, the “C” in USB-C would not have any hidden that means or stand for one more phrase. It’s merely a label that signifies the kind of USB connector you are utilizing, which is USB Kind-C. The letter C is used as a result of it follows the sequential order of the USB household, which had USB-A and USB-B previous it.

The ‘C’ in USB-C would not point out its energy both

USB-C ports assist numerous USB protocols that decide information switch velocity

One other necessary element to find out about USB-C ports is that the “C” would not truly point out how briskly it’s both. Whereas one advantage of USB-C over USB-A and USB-B is its versatility, because it helps a wide range of USB protocols that its predecessors do not, this additionally makes USB-C a bit complicated as a result of not all USB-C ports are the identical.

The info switch velocity of a USB-C port relies on the USB protocol supported by its inside controller chip and the standard of the cable used. USB-C helps many protocols, together with USB 2.0 with speeds as much as 480 Mbps, USB 3.2 Gen 1 with speeds as much as 5 Gbps, USB 3.2 Gen 2 with speeds as much as 10 Gbps, and USB 4, Thunderbolt 3, and Thunderbolt 4 with speeds as much as 40 Gbps.

If you happen to’re interested in how briskly the USB-C port in your machine is, examine the producer’s spec sheet. For instance, the iPhone 17 Pro’s USB-C port is USB 3.2 and helps as much as 10 Gbps, whereas the bottom iPhone 17’s USB port is barely USB 2, which suggests it’s restricted to 480 Mbps. Moreover, the charging velocity of a USB-C port relies on the machine’s inside design and the way a lot energy it could possibly settle for from a charger. Like information switch, charging speeds additionally rely upon the standard of the USB-C cable, so earlier than shopping for simply any USB-C cable, examine the supported speeds to keep away from limiting your machine’s efficiency due to the cable.
