10. ⦿ IE E E i s bes t kno w n f o r developing standards for the computer and electronics industry. In particular, the IEEE 802 standards for local-area networks (LANs) are widely followed.

11. ⦿ IEEE 802 refers to a family of IEEE standards dealing with local area networks and metropolitan area network. ⦿ IEEE 802 splits the OSI Data Link Layer into two sub-layers: LLC(logical link control) sub layer MAC(media access control) sub layer

12. IEEE 802.1 (networking) and Network Management IEEE 802.2 Logical link control (upper part of data link layer) IEEE 802.3 Ethernet (CSMA/CD) IEEE 802.4 Token bus (disbanded) IEEE 802.5 Defines the MAC layer for a Token Ring (inactive) IEEE 802.6 Metropolitan Area Networks (disbanded) IEEE 802.7 Broadband LAN using Coaxial Cable (disbanded) IEEE 802.8 Fiber Optic TAG (disbanded) IEEE 802.9 Integrated Services LAN (disbanded) IEEE 802.10 Interoperable LAN Security (disbanded)

13. IEEE 802.11 Wireless LAN & Mesh (Wi-Fi certification) IEEE 802.12 demand priority (disbanded) IEEE 802.13 Not Used IEEE 802.14 Cable modems (disbanded) IEEE 802.15 Wireless PAN IEEE 802.15.1 (Bluetooth certification) IEEE 802.15.4 (ZigBee certification) IEEE 802.16 Broadband Wireless Access (WiMAX certification) IEEE 802.17 Resilient packet ring IEEE 802.18 Radio Regulatory TAG IEEE 802.19 Coexistence TAG IEEE 802.20 Mobile Broadband Wireless Access IEEE 802.21 Media Independent Handoff IEEE 802.22 Wireless Regional Area Network

15. It defines Logical Link Control (LLC) as the upper portion of the Data Link Layer. The IEEE 802.2 sub layer adds some control information to the message created by the upper layer and passed to the LLC for transmission to another node on the same data link.

16. ⦿ Defines the MAC layer for bus networks that use CSMA/CD. This is the basis of the Ethernet standard.
