To anyone who can help.

I am not a military  pilot, but I love to read alot of aviation books. I was recently reading a naval Aviation Book about life on a Carrier during Dessert Storm and some terminology was used many times which I don't understand. It's called "Entering the Break" and "Breaking the Deck". These terms are used alot....Any I don't quite get what they are talking about during the landing sequence. This may be a really stupid question..... but if someone could help this old guy (43) understand these terms, It would help me appreciate the book which i am reading. Thank You in advance
