Networking Topologies and Media
Network Topologies
The physical arrangement of the cables, computers and components is referred to as
the networks topology. There are five basic topologies, bus, star, ring, mesh, and
wireless. More ...
Ethernet Network
In 1973 Xerox invented Ethernet to solve the problem of transferring data between
computers. In the early 1980s Xerox turned over control of the Standard to the
Institute of Electrical and Electronics Engineers (IEEE). The IEEE subcommittee
802.3 sets the standard for Ethernet. More ...
The IEEE 802.3 Ethernet Standards
The Institute of Electrical and Electronics Engineers (IEEE).
The IEEE sets up committees to define industry standards. The IEEE 802 committee
sets the standards for networking. The IEEE subcommittee 802.3 sets the standard
for Ethernet. More ...
Token Ring Network
In 1984 IBM invented Token Ring. The token ring network may be setup with a physical
ring topology, but is usually implemented in a physical star topology. The central
device of the token ring is called a Multistation Access Unit. More ...
Fiber Distributed Data Interface
The Fiber Distributed Data Interface (FDDI) uses pulses of light and fiber optic
cable to send signals with a 100 Mbps throughput over dual counter-rotating rings.

Wireless Networks
A wireless LAN (WLAN or WiFi) provides network connectivity by using radio waves
rather than cable. Wireless devices can communicate with each other or they can
communicate through a wireless access point (WAP) to a wired network. More ...
System Area Network Interface Cards
Servers in a cluster communicate over a separate System Area Network. Whereas the
standard network may use twisted-pair cabling, the System Area Network may use
fiber-optic cabling. System Area Network interface cards are special high speed
circuits that provide communications between the servers over the System Area Network. More ...
