In a binary code, the bit or bit position that is assigned to, or represents, the smallest quantity or increment that can be represented by the code.

Synonym Fermat's principle.

When a multicast host sends the proper IGMP or MLD message to no longer be part of the multicast distribution tree.

Each subnetwork that contains at least one multicast host is know as a leaf. In the case of IPTV, the Home Network utilizing the IPTV service becomes a leaf of the IPTV multicast distribution tree. When new leaves are added to the tree, a branch is created. Branches that no longer contain a leaf will be pruned from the tree.

Abbreviation for light-emitting diode.

An elliptically or circularly polarized wave, in which the electric field vector, observed in the fixed plane, normal to the direction of propagation, whilst looking in the direction of propagation, rotates with time in a left-hand or anticlockwise direction. [NTIA] [RR]

1. A segment of an end-to-end route or path, such as a path from user to user via several networks and nodes within networks.
Note: Examples of legs are several sequential microwave links between two switching centers and a transoceanic cable between two shore communications facilities, each connected to a node in a national network.
