In computer networking, a frame is a digital data transmission unit on the Layer 2 of the OSI model.[1]
RFC 1122[2] defines a frame as: "the unit of transmission in a link layer protocol, and consists of a link-layer header followed by a packet."
Frames are used for data exchange between two points via a direct physical or logical link. Depending on the Layer 2 protocol employed, the receiver of frames uses one of several multiplex techniques to distinguish more than one logical data streams (sometimes dubbed virtual circuits) which run over a single shared medium.
