What are scripts

[infoconsultants]

I have seen lot of people who sell there domain names mention that they have script running on there site to display the content. I have a few questions. i would appreciate if someone can answer them

. What are Scripts ?- the basic question :) apologies for my ignorance
. Where to find them? are they free or where can i buy them
. Where does the script get the data to be displayed from? Is there a common pool of data from where it picks up the relevant one?
. Is it customised to the specific site or is it generic

Thanks for your time
