Linux.com: Introduction to Networking, Part 1: Physical Media

(Other stories by Chris Campbell)

"Physical Media refers to the actual wires of the network that are used to carry the signal. This is the primary focus of this article...."

"To create a basic network, first we need to acquire the physical media. NICs can be purchased at local computer stores for varying prices. A Linksys 10/100baseT card sells for about $20 at most places. 3Com 3c5/0xx series 10/100baseT cards retail for around $70. The difference? Preference, typically. Although I can't say that I've had bad luck with Linksys cards, I have extreme faith in 3Com cards. $20 cards are perfectly fine for this example network. Install the cards into the machines, following the directions that come with the devices."

"A hub also may be purchased. Hubs retail from $40 on up. A small $40 four port hub will be fine for this demonstration network. If more than 4 machines are to be added to the network, a larger hub should be purchased. If two machines, the bare minimum for a network, are to be used, a hub isn't necessary. It is preferred, however."
