The 802.11 Group of Standards are specifications for wireless local area networking. The original standard was released in 1997 and many extensions have been added over the years.
802.3 is a networking standard established by the Institute of Electrical and Electronics Engineers (IEEE). Among other things, 802.3 standardized the operation of CSMA/CD. While Ethernet and 802.3 differ slightly in their terminology and their frame format, their media access control (MAC) protocols are virtually identical. Today, the term Ethernet refers generically to both the sets of Ethernet standards.
