Domain Name – The domain name is the actual name of your site. It is the part that appears between the www. and the top-level domain (.com, .net, etc.). There is only one name per top-level domain. In other words, there can be a superstore.com and a superstore.net and supertore.org, but there can’t be two superstore.com sites. Your domain name is registered through one of many registrars.

Domain Name Server (DNS) – Your domain name is attached to a DNS, which is expressed as a series of numbers or a combination of numbers, initials and names. Whenever you ask your browser to find a particular web address, the browser consults a huge data table that matches the name with the number and then directs the request to the proper site. This allows users to enter a more memorable name instead of an actual address, which would be something like 5.112.345.32.

Frames – Some sites are created using frames. This is a type of design that uses multiple web pages to create a single web page. Each window may have a scroll bar that allows you to move up and down that section of the page. Frames aren’t as common as they used to be, but they are still in use on some sites.

FTP – FTP, or File Transfer Protocol, provides you with the ability to transfer entire files from one computer to another. It is used on websites to load web pages from your local computer onto the server where your site is located.

Header – This is a portion of your web page that contains information that helps your browser understand how to load the page and what it needs to do once it’s loaded. Some of the information in the header is not visible to the person viewing the site. This includes Descriptions, Keywords and other fields that add functionality to the site.

Host – This is the computer that stores your web documents and delivers the pages to users. See server.
