How to explain the meaning of scripting language?

[Ruperorit]

How can scripting language be explained or rather defined in layman terms. Is it responsible for security of Java-based applications? What are run-time and compile-time check and what are the various steps involved in it? How can robustness of Java applications or Java language be explained?

Those are all very good questions. Now I have one: How can an Ad-Bot that doesn't advertise be explained? Maybe it's just like in the Matrix where the programs are constantly yapping about choice. ..Do bots have a choice?
