Information about Domain names

What are domain names?

Domain names are the word sequences users enter in the web browser (address bar) to go to a specific site. Each web site (domain name) has an IP assigned. The translation from the domain name to the IP address is done by a DNS (Domain Name Server).

URL stands for:Uniform Resource Locator. This is often used with the term http:// wich stands for Hypertext Transfer Protocol.  So "http" is just a scheme for transporting information. there are more schemes (ftp).

Regardless of the scheme, it all comes down to the same: URL, domain name is just a Web address. Any time you come across a URL, you can navigate your way to it using a Web browser.

Difference URL vs URI?

URI stands for Universal Resource Identifier and URL stands for Universal Resource Locator.

They are not the same. A URL is a subset of the URI protocols (http://  ftp://  mailto:) Therefor all URL's are URI's. All URIs are designed to access a resource on the Internet and are a technical abbreviation used to link to the resource.
