A Thunderbolt 2 connector is essentially an alternative to USB. Developed by Intel, it allows you to connect various devices to a laptop or desktop. A Thunderbolt 2 dock makes it convenient to keep multiple devices connected to your laptop, since the only cable that needs to be plugged into the computer is the Thunderbolt — the rest sit in the dock. Thunderbolt 2 docks typically come with ports for USB 3, eSATA, and HDMI, but some have others, such as Firewire and Ethernet. Some allow you to “daisy chain” devices, meaning you can connect devices to one that’s connected to the dock so that they can all interact. You need two Thunderbolt ports to achieve this, so a dock that includes them expands connectivity options.
