Main functions of USB type-c interface
USB type-c interface has four main functions: fast, versatile, two-way, backward compatibility. Here are the details:
Theoretically, the usb-c port has a maximum transfer rate of 10GB per second. But apple says the new MacBook's usb-c port has a top speed of 5GBps. The maximum output voltage is 20 volts, which can accelerate the charging time. The usb-a, by far, has A maximum transmission rate of 5GBps and an output voltage of 5 volts.
The new MacBook's usb-c port can be used for data transfer, charging, or connecting to external display devices as a video output port. The only question is how apple can satisfy users who want to do all three at once.
3. The two-way
Unlike the older USB ports, which can only transmit power in one direction, usb-c ports transmit power in two directions, meaning it can send power in two ways. So, users can not only charge their mobile devices with their laptops, but also with other devices or mobile power sources.
4. Backward compatibility
Usb-c is compatible with the old USB standard, but users need to purchase an additional adapter to complete the compatibility. Apple says not only will apple officially sell the adapters, but third parties can also license them.
