Net + lesson 3

Today, we are going to discuss in Net + about topologies. Some say that topologies are the hardest concepts to capture in Net +... But i think it's the easiest thing to learn out of all there is to learn in Net +.
There are four main types of topologies:
-Bus
-Ring
-Star
-Mesh
They are all pretty much self explanatory. But we have to go into a simplistic way of looking at all of these Topologies in Net +. I'll explain it the same way as I've understood it.

Bus topology:
Imagine a school bus... go ahead... did you imagine a bus yet? What a bus topology is... just that... a row of computers in a line all connected to one another. there is computer A connected to B... B is connected to C... etc... and they are all linked! So if one crashes... they all crash!

A Ring topology:
Just like a bus... imagine a circle... with computers all surrounding the entire ring. But this one has a File Server and Mau... in order for them to work... none of the computers can be broken!

Star Topology:
It seems to be the best... because the way it is set up... that if one computer is broken or working improperly... all the other computers won't be affected... So There is a central hub... which has it's own connections to each different computer... which makes networking easy!

Mesh topology:
Think of Mesh topology as a messy topology... it's like a group of three freinds... that live in different parts of the state... and they all stay connected to one another... like this...

ABCD
EFGH

A connects to E... F... G.... H
B connects to E...F...G...H...
ETC!!!

More next time folks... more on Net + and Networking!
