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

You doubtless work together with a USB port day by day, whether or not you are plugging in your cellphone to cost or connecting a tool to your PC. Lately, USB-C, also called USB Sort-C, has turn into the most typical kind of USB port, seen on most smartphones, laptops, tablets, gaming consoles, e-readers, and lots of different units.

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

I actually hadn’t thought a lot about USB-C recently as a result of it is turn into so synonymous with all of the tech I take advantage of that I’ve simply grown used to it. Nonetheless, that modified just 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 expertise: regardless of its widespread use by hundreds of thousands and even billions of individuals day by day, many may not really 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. If you have a look at a USB-C port or connector, it is not really formed just like the letter C, so that is not the which means. My pal assumed it stood for connector, which is an affordable guess however not the reply both. To essentially perceive the which 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 does 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 firms — 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 turn into important to many technological improvements, together with smartphones, tablets, e-readers, and extra.

USB-A might be the USB port you are most acquainted with, because it’s the oblong connector that is been used on units for effectively over 20 years now, and continues to be generally seen in the present day 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 lately, USB-C has largely taken over its place, because of its compactness and in addition its means to deal with quicker information switch and charging speeds.

You may be much less acquainted with USB-B, a bulkier sq. connection usually seen on printers and exterior onerous drives. You might also discover USB-B ports on the again of screens, the place they function upstream ports, which means they ship information from the opposite USB ports in your monitor again to your PC. So in the event you join a keyboard to your monitor’s USB-A port, you may must plug the USB-B port into your PC as effectively, so it could actually use it. Micro USB, which was once on lots of smartphones again within the day, can 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. In contrast to 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 be way more compact than USB-A and USB-B, which means it takes up method much less house on units. 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 maintaining the units skinny and lightweight.

So, to recap, the “C” in USB-C does not have any hidden which 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 Sort-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 does not point out its energy both

USB-C ports help numerous USB protocols that decide information switch pace

One other vital element to find out about USB-C ports is that the “C” does not really 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 quite a lot 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 information switch pace of a USB-C port is determined by 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.

In case you’re interested in how briskly the USB-C port in your machine is, verify 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 pace of a USB-C port is determined by the machine’s inside design and the way a lot energy it could actually settle for from a charger. Like information switch, charging speeds additionally depend upon the standard of the USB-C cable, so earlier than shopping for simply any USB-C cable, verify the supported speeds to keep away from limiting your machine’s efficiency due to the cable.
