Blog is short for "web log". It's more like a diary that most people used to keep when they where younger, or back in the old days when people used to a keepa record of their everyday life. The web part simply means that it's available on the web for everyone to access, although in some cases it might be password protected.

There are many site available today where you can start your own blog for free and without any advance knowledge of web pages. Blogspot is a good one. For advance blogging with full control over your blog try TypePad, or install Movabletype (that's what I use!) if you have your own webserver.

Blogs are evolving from just pages of text to PhotoBlogs, MoBlogs, and even audBlogs.
