Detailed explanation-1: -A frame is a unit of data transmitting over the data link layer. The data link layer header and the payload data come together to construct a frame. The data part of a frame is a packet from the network layer. In other words, a frame encapsulates a packet.
Detailed explanation-2: -Frame Structure and Frame Header Besides, the frame header contains the destination and the source addresses. The info field contains the data frame that may be either of fixed length or of variable length. The frame may have a trailer, also called frame check sequence (FCS).
Detailed explanation-3: -The main difference between a packet and a frame is the association with the OSI layers. While a packet is the unit of data used in the network layer, a frame is the unit of data used in the OSI model’s data link layer. A frame contains more information about the transmitted message than a packet.
