There are lots of terms associated with the Internet that are unique, confusing, or just downright strange. We've gone over a few of them in our earlier tutorials, but here's a more complete list of some of the common Internet-related terms you'll hear.
Blog -- short for "web log", a website or service that allows someone to periodically record their thoughts, feelings, and opinions, similar to a diary or journal. Many are text-and-picture, but some are made of video or audio recordings.

Dynamic websites run background processes that allow them to be updated in some ways with or without a user's actions, often without needing certain web pages to be reloaded from their servers.
Web browser -- A program that allows a person to access the World Wide Web by asking for website or web page information from server computers, displaying that information, and allowing the user to move from one website or web page to another by clicking hyperlinks.
