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

You doubtless work together with a USB port on daily basis, whether or not you are plugging in your telephone to cost or connecting a tool to your PC. Lately, USB-C, also called USB Sort-C, has grow to be the most typical kind of USB port, seen on most smartphones, laptops, tablets, gaming consoles, e-readers, and plenty 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 currently as a result of it is grow to be so synonymous with all of the tech I exploit that I’ve simply grown used to it. Nonetheless, that modified lately when my buddy, 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 side of know-how: regardless of its widespread use by hundreds of thousands and even billions of individuals each day, many won’t 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. Whenever 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 buddy assumed it stood for connector, which is an inexpensive 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 most recent USB connector

It’s the successor to USB-A and USB-B

The explanation USB-C has its identify 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 most recent 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 grow to be 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 remains to be generally seen right this moment 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 capacity to deal with sooner information switch and charging speeds.

You could be much less accustomed to USB-B, a bulkier sq. connection sometimes seen on printers and exterior exhausting drives. You may additionally 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 the event you join a keyboard to your monitor’s USB-A port, you will have to plug the USB-B port into your PC as properly, so it may use it. Micro USB, which was on a whole lot 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, that means it takes up approach much less house 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 light-weight.

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 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 would not point out its energy both

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

One other necessary element to learn about USB-C ports is that the “C” would not truly point out how briskly it’s both. Whereas one good thing about 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 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 the event you’re inquisitive about how briskly the USB-C port in your machine is, test 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 just USB 2, which suggests it’s restricted to 480 Mbps. Moreover, the charging velocity of a USB-C port is determined by the machine’s inside design and the way a lot energy it may 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, test the supported speeds to keep away from limiting your machine’s efficiency due to the cable.
