Unique Domain Authentication ID (UDAI)
The Unique Domain Authentication ID, or UDAI, is a randomly generated unique identifier that is required to authenticate requests to transfer domain names from one registrar to another. A UDAI is generated when a domain name is registered, although the domain name's registrar can generate a new UDAI at any time if required. Registrars are obliged to promptly make UDAIs available to registrants upon request and may not withhold them to prevent a domain name from being transferred under any circumstances.

URL

URL is the abbreviation for Uniform Resource Locator and is an address referring to a document on the Internet. In other words, it is the address of an individual web page element or web document on the Internet. The syntax of a URL consists of three elements:

* the protocol, or the communication language, that the URL uses;
* the domain name, or the exclusive name that identifies a web site; and
* the path name of the file to be retrieved, usually an HTML document.

Most newbies mistakenly believe a URL is the same as a domain name or home page. Every web document and web graphic image on a web site has a URL.

For example, the URL for a home page is commonly written as:

http://www.yourbusinessname.com/index.html

o The http:// is the protocol.
o The www.yourbusinessname.com is the domain name.
o The index.html is the path name.

The URL for an About Us page is commonly written as:

http://www.yourbusinessname.com/about.html

o The http:// is the protocol.
o The www.yourbusinessname.com is the domain name.
o The about.html is the path name.
