In many Laptops, we have seen USB type-C connectors. However, these connectors don’t​ just support the USB type-C interface, they also support Thunderbolt.
Thunderbolt is the brand name of a hardware interface developed by Intel (in collaboration with Apple) that allows the connection of external devices to a computer. Initially, Intel used optical cables for transmission that only allowed data to be transmitted. With the introduction of Copper cables in thunderbolt software, data and power became easily transmittable.
Thunderbolt transmits via duplex lanes that use data lanes to form connections to PCIs and DisplayPort devices. A single Thunderbolt port can use hubs or daisy chains to support up to six devices at once. Initially, the Thunderbolt Software connector looked like a Mini Display Port, the only difference was that the supported devices and cables had a thunderbolt logo that identified them as Thunderbolt cables.
There are 3 versions of Thunderbolt Software: Thunderbolt 1, Thunderbolt 2, and Thunderbolt 3. Let’s look at the features of each.
