Understanding Domain Names

Using the
Internet can be a bit daunting at first. There are so
many terms and short cuts people talk about, and it can
be confusing.
In simpler
terms, each web site on the Internet has a name that is
used to find that site. That name is called the URL
(universal Resource Locator) of the site and usually
takes the form of
http://www.domainname.extension
Some web sites
can be identified without specifying the “http:” so
typing
www.domainname.extension will be sufficient; other
sites don’t include the “www” and will just be
http://domainname.extension.
Each site
selects its own domain name; ideally, the domain name
will give you an indication of the site’s purpose and
usefulness to you. It may include the company or
organization name, or some other term. Examples of
domain names are savetimeonline, wordconstructions,
businessmums, IBM, ninemsn and abc.
The extension of
a URL is a short abbreviation that can tell you about
the site. Some of the most common extensions are listed
below with a simple definition of the type.

.biz |
Business |

above |
Often, you will
see more letters after the three letter extension. These
are usually an indication of where the site is based; a
lack of a country code may represent the USA, but many
non USA sites don’t include a country code either as it
is not compulsory to do so. Most countries, however, do
have regulations in place about who can use their
country code.
A three letter
code and the country code are both classed as an
extension.
Common country
codes are as follows:
Code |
Country |
Code |
Country |
.au |
Australia |
.nz |
New Zealand |
.uk |
United
Kingdom |
.ca |
Canada |
.jp |
Japan |
.us |
USA (not
often used) |
.sg |
Singapore |
.it |
Italy |
.my |
Malaysia |
.fr |
France |
.ch |
China |
.de |
Germany |
When computers
are looking for the site you request, they read from
right to left; it is comparable to a postal service
reading an envelope from the bottom up. First step is
knowing which country is relevant, second step is the
area (of the country or of the internet), and so on.
The right hand
extension is known as a first level domain and is the
controlling feature. Once a URL includes a country code,
other extensions are as specified by that country.
For instance,
company xyz could have the url
www.xyz.com. If it is a British business, it may
become
www.xyz.co.uk as this is the standard ending for
British businesses.
Once you
understand some basics of URL naming, you can interpret
differences without too much trouble. A little more
knowledge about URLs can save you from looking at
irrelevant sites.
