  Intel releases Light Peak technology called Thunderbolt (Thunderbolt interface), commonly known as Thunderbolt interface. Thunderbolt connection technology combines PCI Express data transmission technology and DisplayPort display technology, which can transmit data and video signals simultaneously, and each channel provides two-way 10Gbps bandwidth. The latest ThunderboltTM 4 reaches 40Gbps.
  Due to the popularity of Type-C interface and the beginning of Thunderbolt3, Intel announced that it will change the original mini DP interface of Thunderbolt to Type-C interface. The following figure is an example:
