Learning about Thunderbolt 3, USB-C, USB 3.1 2nd Gen. connections

Learning about Thunderbolt 3 and USB-C connections from “USB Type-C and Thunderbolt 3: One port to connect them all” on https://www.cnet.com/how-to/usb-type-c-thunderbolt-3-one-cable-to-connect-them-all/
. Here’s how Thunderbolt 3 is different from its predecessors:
The Mini DisplayPort connection type has been ditched in favor of a USB-C connection type.All Thunderbolt 3 cables will work as USB-C cables.All USB-C cables will work as Thunderbolt 3 cables as long as they are good quality cables.Thunderbolt 3 has a top data transfer speed of 40Gbps as long as the cable is 0.5m (1.6 ft.) or shorter.For 1m (3.2 ft.) or longer cables, Thunderbolt 3 supports passive (cheaper) ones that have a top speed of 20Gbps, and active cables (more expensive) that retain the 40Gbps speed.Thunderbolt 3 is backward-compatible with earlier versions of Thunderbolt, but due to the new port type, adapters are required to use legacy Thunderbolt devices.Any USB-C device (like a Google Pixel) plugged into a Thunderbolt 3 port will function normally.Since Thunderbolt 3 devices use discrete Thunderbolt chips to function, they will not function if plugged into a USB-C port.All versions of Thunderbolt allow for daisy-chaining up to six devices together to a host and in addition to data, can also carry Hi-Def video and audio signals.
. USB 3.1 (sometimes refereed to as USB 3.1 Gen 2., [or now called SuperSpeed+ or SuperSpeed USB 10 Gbps)): Released on July 26, 2013, USB 3.1 doubles the speed of USB 3.0 to 10Gbps (now called SuperSpeed+ or SuperSpeed USB 10 Gbps), making it as fast as the original Thunderbolt standard. USB 3.1 is backward-compatible with USB 3.0 and USB 2.0. USB 3.1 has three power profiles (according to USB Power Delivery Specification), and allows larger devices to draw power from a host: up to 2A at 5V (for a power consumption of up to 10W), and optionally up to 5A at either 12V (60W) or 20V (100W). The first USB 3.1 products are expected to be available in late 2016, and will mostly use USB Type-C design.
