Techopedia Explains IEEE 802

IEEE 802 subdivides the data link layer into sublayers, namely the logical link control (LLC) and media access control (MAC) layers, which provide protocol multiplexing and a multi-access mechanism, respectively.

IEEE 802 is comprised of standards with separate working groups that regulate different communication networks, including IEEE 802.1, 802.3, 802.11 and 802.15.
