URL
A Uniform Resource Locator or URL is the common address system computers use to link to each other on the world wide web. It is a highly scalable, simple system that allows for plenty of flexibility.
Anatomy:
This is the order in which a computer or server processes a URL:
1) http:// - This tells the computer that a web page is being opened
2) .com - The Top Level Domain (TLD) server is asked if it knows about the
domain name (leveltendesign)
3) leveltendesign - The domain name. It is a unique alphanumeric address. It is
asked if it knows about the subdomain (www)
4) www. - This is the subdomain. This is most commonly www for a web site. This is the specific [[web server]] on the computer hosting the domain name.
5) /wiki/index.php - This is the file on the web server being accessed
6) ?title=URL - After the question mark is a query string of values that change the output of dynamic files
