Networking Help

[Broken Angel]

I bought myslef Networking Bible for some good read by Barrie Sosinsky and while going throught the first chapter itself I got stuck to a point, the book says:

well the topic is Physical Topologies

With a single link, a permanent point-to-point mesh topoligy between nodes is the simplest arrangment that exxists and the most impractical. To service n endpoints would require 2(n+1) connecctions, which for any large network would require an unstoppable infrastructure of permanent connections. Most poit-to-point networks, like the telephone networks are switched, elimination the need to have point-to-point connections between every node.

Now this whole part was out of my mind.... Mind pls telling me what is the Author talking about in here pls?

In Mesh topology every computer has a line connection with every other computer on the network. so if you have 6 computers on a network, computer 1 has a cable running to computers 2, 3, 4, 5, and 6, and so on down the line

Unlike star topology where all 6 computers would have 1 line each running to a switch in the center, or bus topology where one line would run as a backbone with branch lines connecting each computer to the branch.

Mesh topology, as you can probably see, needs a cable per computer -1... and this can be a lot of cable if you have a lot of computers.
