Background Information
The Institute of Electrical and Electronics Engineers (IEEE) 802 committees that deal with various standards
for different LAN media are as follows:
• 802.2 − Committee that defines the Logical Link Control (LLC) common to many 802 networks
• 802.3 − Committee that deals with the carrier sense multiple access with collision detection
(CSMA/CD) LAN
• 802.4 − Committee that deals with the token bus LAN
• 802.5 − Committee that deals with the 4−Mb and 16−Mb Token Ring LAN
The four types of Ethernet encapsulations are as follows:
