(1 marks each for 2 difference)

Note: Award marks on correct definition of both if difference is not given.

(d) How is a domain name different from a URL? Give examples of domain names and

URLs.

(2)

URL stands for Uniform Resource Locator. It is a web address i.e. a reference to a

web resource that specifies its location on a computer network and a mechanism for

retrieving it.

Domain names are used in URLs to identify particular Web servers.

For example, in the URL http://www.cbse.nic.in/welcome.htm, the domain name is

www.cbse.nic.in.

A domain name usually has more than one parts: top level domain name or primary

domain name and sub-domain name(s). For example, in the domain name, in is the

primary domain name; nic is the sub-domain of in; cbse is the sub-domain of nic.

There are only a limited number of top level domains, and these are divided into two

categories: Generic Domain Names (.com, .net, .edu) and Country-Specific Domain

Names (.in, .uk, .au).
