Usb-c is the industry standard connector for transferring data and power over a single cable. Usb-c connector is developed by usb-if, a group of companies that have developed, certified and promoted the USB standard over the years. Usb-if has more than 700 members, including Apple, Dell, HP, Intel, Microsoft and Samsung.
Widespread adoption by large companies is important, as this is part of the reason why usb-c is easy to adopt by PC manufacturers. In stark contrast to the Lightning and MagSafe connectors that Apple promoted (and developed), Lightning and MagSafe connectors had limited adoption outside of Apple products and were quickly phased out by usb-c.
Is usb-c like Micro USB?
At first glance, the usb-c connector looks similar to the mini USB connector, but has a more elliptical shape and is slightly thicker to accommodate its best feature: rolability.
Like Lightning and MagSafe, the usb-c connector has no up or down direction. Arrange the connectors correctly and insert without flipping the connector. Both ends of the cable also have the same connectors, so it's not necessary to figure out which end is where. We've been using all the USB cables for the last 20 years, but that's not the case. In most cases, each end has a different connector.
Basic support: many USES of usb-c
You might think of the old USB type-a port as just A data port to connect to peripherals such as A drive or mouse, but usb-c can do much more depending on the implementation of A particular port. Usb-c supports sending video signals and power streams at the same time, which means you can connect to and power a local DisplayPort, MHL, or HDMI device, or connect to almost any other device with the right adapter and cable. The usb-c specification even considers audio transmission on the interface, but so far it hasn't replaced the 3.5mm headphone jack on computers, as some Android phones do.
Lei li 3: increases speed on usb-c
The most useful protocol that usb-c ports can support is probably Thunderbolt 3, which adds support for up to 40Gbps throughput while reducing power consumption and being able to move up to 100 watts through the interface.
The usb-c port that powers Thunderbolt 3 means that a single cable is all it takes to power up and transmit large amounts of information (up to two 60Hz 4K screens) between or even out, an advantage that many laptop makers have been quick to exploit. For example, the top-of-the-line version of Apple's MacBook Pro has four of these connectors.
Now, like the DisplayPort via usb-c, not every usb-c port will necessarily support Thunderbolt 3. Look for the lightning sign next to the port. However, this will change with the upcoming USB 4 standard. The USB 4 port will support Thunderbolt 3 speeds by default while still being backward compatible with USB 3. Some new devices may have both USB 4 and USB 3.2 Gen 2×2 ports, both of which will take advantage of usb-physical connector shape C.
Do you need usb-c?
The presence or absence of a usb-c port is a growing consideration when buying a PC. If you buy an ultra-thin laptop, it will almost certainly have at least one usb-c port, and if you prefer desktops, at least one port on the motherboard side I/O panel, and probably more on high-end desktops and gaming desktops.
