Hello aspirant,

IEEE 802 is a family of Institute of Electrical and Electronics Engineers (IEEE) standards for local area networks  (LAN), personal area network (PAN), and metropolitan area networks (MAN). The IEEE 802 LAN/MAN Standards Committee (LMSC) maintains these standards. The IEEE 802 family of standards has twelve members, numbered 802.1 through 802.12, with a focus group of the LMSC devoted to each.

The services and protocols specified in IEEE 802 map to the lower two layers (data link and physical) of the seven-layer Open Systems Interconnection (OSI) networking reference model. IEEE 802 divides the OSI data link layer into two sub-layers: logical link control (LLC) and medium access control (MAC), as follows:

• Data link layer
  • LLC sublayer
  • MAC sublayer
• Physical layer

Hope this helps you

All the best for your future
