Cynapse ,
A "Tech Tree" is the series of techs that must be learned in consecutive order to get from one to another.
I don't have the exact vocabulary handy but:
On a simple level:
Missle I leads to Missle II etc
In many cases Reasearch in one tech area leads to Discovery of a new Tech area.
Reasearching Physics opens up 3 or 4 other areas.

Folks feel free to help me out here. My notes are at home. (Ok, the dog ate my homework)
