What is trunk?

Answer 1

The trunk is the main section of the body (thorax and abdomen), containing all the important support systems and relevant organs. It is also the long, prehensile facial appendage of the elephant - its nose.

'Trunk' is also a slang reference for the posterior ('booty'). It is also a reference to the rear storage compartment of certain types of vehicle ('car boot'), or to storage/baggage containers of a specific design- usually of box-like construction with a hinged lid.

Answer 2

Trunking means that several connections in a network may be established simultaneously, and that setup of connections proceeds automatically using the channels available at the time in question. In this way many users may share a few connections, and if the number of connections is increased, the capacity of the network is increased more than proportionally. This means that an optimal trunking effect is obtained in very large networks. Commonly used with VOIP networks.
