A frame is a fragment of data sent through a network connection. A frame contains additional information that allows the recipient to retrieve the beginning and end of a frame from a series of bits or symbols. The recipient ignores all received data until a frame has been detected, and ignores all information again after the frame is closed. A frame is used in the OSI model data link layer. It consists of a header (this indicates the beginning of the frame) and a set of data.
FormatA frame has different shapes, but the base remains the same for each application. A frame always consists of a header and a piece of data. In the header is the address of the recipient and the sender. For example, with the IEEE 802.11 codec, a check bit is added to the frame next to the header and the data. Applications
Frames are used in all applications where data should be transmitted by bit. In other words, all applications that use the OSI model's second layer (the data link layer). Some examples of this are IEEE 802.11, Bluetooth and WiMax. Also see Sources
