How many computers?

The number of computers is not real important, it is really the amount of traffic which will limit you. If utilization gets over 30%, collisions goes way up. With switches so cheap, why use hubs? I tried to remain child-like, all I acheived was childish.
True..
Collision domains though are layer one devices ie repeaters hubs that basically copy data to each port therefore if you have a 16port hub you have one collison domain. Now if your network is entirely hubbed then you can get into trouble very quicky after the 5/6th hub you add because it is one collison domain and one broadcast domain and like the last person said once past 30 % dont expect much response. If you have switches in you network then each port on the switch is a seperate collision domain so break up the hubs and put a switch in the middle to interconnect get the idea. Thats collisions. With a switch you get one broadcast domain (unlessed VLANd) so the below is really a guide for once you have your collision / broadcast domains sorted.
I Stress they are basic guidelines for design. Work on protocols IP maximum 500 IPX 300 Netbeui 200 mixed 200/300 please bear in mind to learn you traffic if you have 900+ users that just connect to a terminal emulator and use occasional w/p etc then one would be fine but work on broadcasts ie employ DNS WINS properly.
