What are Nodes?
In what context is the word used?
In a computer analysis, a node refers to a branch of play the computer investigated. For example, a node with depth 4 from the opening position could be e4 e5 Nf3 Nc6. The computer would then use a function to calculate the value of that node based on the resulting position. See http://en.wikipedia.org/wiki/Minimax for more.
