This just means that you will be able to connect a Type-C USB cable or device without worrying about its direction. USB has had multiple iterations since its inception in The main differences between the various USB versions are its transfer rate and the amount of power they can supply. Transfer rate definition: Transfer rate is the maximum rate in which the USB device is able to transfer data from one end to another. USB 2.
USB 3. Another difference between the different versions is the amount of power they can deliver. What this means is that the newer the port, the more energy it can bring to a connected device. A device where this is relevant is the external hard drive, as a 3. This enables Type-C cables to charge laptop batteries, and not just phones and tablets.
Type-C devices also support video input and output. A hub typically has four new ports, but may have many more. You plug the hub into your computer, and then plug your devices or other hubs into the hub. By chaining hubs together, you can build up dozens of available USB ports on a single computer. Hubs can be powered or unpowered.
A high-power device like a printer or scanner will have its own power supply, but low-power devices like mice and digital cameras get their power from the bus. The power up to milliamps at 5 volts comes from the computer. If you have lots of self-powered devices like printers and scanners , then your hub does not need to be powered -- none of the devices connecting to the hub need additional power, so the computer can handle it.
If you have lots of unpowered devices like mice and cameras, you probably need a powered hub. The hub has its own transformer, and it supplies power to the devices that connect to the hub so the devices do not overload the computer's power supply. The Universal Serial Bus can easily handle both a scanner and a printer, even if you are scanning and printing at the same time. Sign up for our Newsletter! Mobile Newsletter banner close.

The massive increase in bandwidth has allowed for things like computer monitors, ethernet cards, Wi-Fi adapters, and all sorts of other things to be connected to a PC without having to open it up and use up slots. Remember those? When USB 3. That's the small, reversible oval connector that we all now know and love.
But it's making its way onto all kinds of consumer electronics. Currently, many laptops only have a USB-C connector on them. The biggest offender here is Apple's MacBooks since the company has been very aggressive about ripping out ports over the years. Still, they are not the only ones.
Companies like Dell, Lenovo, HP, and Microsoft have all been making their products thinner and streamlined. We are getting fewer ports from them due to a desire to make everything light and wirelessly connected. Each of these connectors can function as a USB 3. Thunderbolt, a standard created by Intel, is even faster. It can transfer data at up to 40Gbps.
That means you could conceivably connect things like external graphics processors to a laptop with one of these ports if the operating system supports it. Or a high-speed 10Gbps network adapter, for example, if you were one of those people who need to transfer huge data files, like someone working in special effects or a video-editing studio. So, this was before the USB-C connector.
It's a special pin connector. You've probably seen it: It resembles a big rectangle with a notch cut out of it. Virtually all of the desktop monitors you can buy now have DisplayPort connectors on them, in addition to the HDMI or the DVI connectors you normally find on older monitors. So, before you know it, you're lucky to have one spare port left.
That doesn't leave room for a mouse, a keyboard, or anything else; you'd better hope you have Bluetooth stuff to connect to it. That allows you to use a single USB-C port to connect to multiple external monitors, provided your monitors have both DisplayPort input and output ports. There is an upper limit of five monitors with DisplayPort using a daisy chain -- but at a lower resolution.
