Q.8 What is a URL?
A
A URL is an address that is written in a way so that it is easy for the DNS function to
determine on which server the IP address is located.
This address begins with "http:// " and is followed by such things as domain names, server
names, port numbers, fi le names and other such info.

For example, if the IP address that is assigned to "www.tandd.com" is "61.197.203.107",
by entering "http://61.197.203.107/product/wdr_3/tr_7w_01feature.html" in the browser,
the same page will appear as when you enter "http://www.tandd.com/product/tr_7w/
tr_7w_01feature.html".

The DNS or Domain Name Server helps to switch diffi cult to understand IP address of just
numbers, such as "61.197.203.107" into easy to grasp names such as "www.tandd.com"
and helps connect to the desired server.
