Question

I need help finding information on Topology and the four principals... bus, ring, star and tree.

Answer 1

Since this is not my area of expertise, I searched Google under the key words "<I>topology bus ring star tree</I>" to get these possible sources:

http://compnetworking.about.com/od/networkdesign/a/topologies.htm
http://fcit.usf.edu/network/chap5/chap5.htm
http://www.webopedia.com/TERM/t/topology.html
http://en.wikipedia.org/wiki/Network_topology
(Broken Link Removed)

In the future, you can find the information you desire more quickly, if you use appropriate key words to do your own search.

I hope this helps. Thanks for asking.
