A virtual domain name is a series of alphanumeric characters separated by
one or more periods or dots. Domain names are often easy-to-remember
names or acronyms that people enter in the URL field of a web browser to
retrieve a web page.
When a domain name is entered, the browser must first makes a request to
a domain name server to obtain the physical address (i.e. IP address) of the
website. Using the IP address, a request for the web page is then sent
across the network (e.g. Internet) and the target web server receives the
requests and responds by returning the web page.
Domain names often end in ".com", ".net" or ".org". There are many
other high level domains, including ones for each country. (e.g. ".ca",
".au") and others for special purposes (e.g. ".tv", ".pro")
