Network Basics
The IEEE (Institute of Electrical and Electronic Engineers) project 802 decided to use Ethernet
version 2 as the basis for its new CSMA/CD network standard. By enhancing the DEC, Intel and
Xerox Ethernet 2 design, they produced the IEEE 802.3 specification, which is now the standard
format for Ethernet based systems.
The name 10Base indicates a signaling speed of 10 million bits per second with a base band
signaling scheme.
•
10BaseT 10Mbs Ethernet running over twisted pair cable 100 meter Max..
•
100BaseT 100Mbs Ethernet running over twisted pair cable 100 meter Max.
Other 802.x standards
The IEEE committee are also responsible for other 802 networking specifications:
•
802.1
, this group produced an overview of the work of the project and defined the LAN
reference model.
•
802.2
, this describes the logical link control services used in all IEEE specified LANs.
•
802.3
, describes Ethernet based networks.
•
802.3z
, describes the Gigabit Ethernet format.
•
802.4
, describes networks using a token-passing bus.
•
802.5
, describes networks using a token-passing ring.
•
802.6
, specifications for a metropolitan area network.
•
802.7
, this group advised other working groups on issues relating to broadband
transmission.
•
802.8
, this group are the technical advisory group for FDDI and fibre optic.
•
802.9
, this group explores integrated data and voice networks.
•
802.11
, group for wireless Ethernet
