Glossary: Common Net Terms Explained

I will be constantly editing this post based on the needs of my readers. There's a lot of lingo thrown about online, and if you don't understand terms you run across often, it can make the online experience a lot less fun. With the definitions, I have also thrown in a lot of advice. If you feel I should expand on a term I define here, comment and I will make a separate post about it. Also, let me know if there's something (a word, phrase or acronym) that you are coming across often that you would like defined. Terms are in alphabetical order.
