Thunderbolt's port is capable of handling audio and video, just like the DisplayPort port most Apple users used in the past. You only need one port to connect video and audio, which is a great convenience.
There will be adaptors this spring that allow users to connect USB and FireWire 400 to Thunderbolt ports. You can connect up to six devices to one Thunderbolt Port, provided they are connected from the Thunderbolt port and then connected with different cables. Nowadays you can easily buy premium quality Thunderbolt 4, by navigating online.

Thunderbolt ports are better than USB ports because the design doesn't allow for the quality of video, audio or speed to be affected by cables connecting one to another. The quality of the connection is not affected by connecting to Thunderbolt ports and then to subsequent cables.
However, you should not connect non-Thunderbolt cable to your chain. It can slow down the performance or cause other problems. Users report that they had to experiment with placing non-Thunderbolt cable in different locations in their chain in order to determine the best place to connect them.
Apple doesn't take long to find the right thing. Thunderbolt 2 offers all the benefits of multiple connectivity, but it also does it twice. Thunderbolt 2 supports direct connections to up to 10 devices, thanks to 20Gbps.
Thunderbolt 2 has five USB 3 fully-powered ports that can power hard drives, SSDs, and optical drives. You can charge your iPhone, iPad, tablet or any other USB-charged device with it. Thunderbolt ports are compatible with both PCs and Macs.
Thunderbolt ports were initially ignored by PCs. However, more companies now build their machines with these accessories in place, or with the option to use the Thunderbolt port.
