Closed Deck -Open Deck

I keep reading references to The Terms "closed deck" and "open deck" in relation to our Scooby engines. Yesterday I did a thorough search on the net and found some really interesting information on this subject, but I still cant get it into my brain what the fundamental difference is between the designs.
I have a 1995 2.0 ltr (EJ20BG5) Legacy N/A.
It seems that if you want to greatly increase horsepower by modifying things, you really need to have "closed deck" to cope with the extra power.(as well as a pile of other mechanical changes).
If anyone can explain these two terms to me, in simple english, I would be really grateful.
I get the feeling that it has do do with cylinder sleeves or something, but really dont understand the basic differences.
