They started talking about “big” dongles.
The red arrow designates the dongle on this USB
A **dongle** is a small piece of hardware that attaches to computer, TV, or other electronic device, and that when attached enables additional functions such as copy protection, audio, video, games, data, or other services. These services are available only when the dongle is attached. The term "dongle" was originally used to refer only to software-protection dongles.
