3. DNS (DOMAIN NAMING SYSTEM)
• Every computing resource on the internet has
a unique number called IP address.
• However, it is easier for us to remember the
names of the websites that we want to access.
• for example, it is easier to remember
www.games.com rather than 202.56.6.68.
• The domain naming system is a system is a
system designed to translate the English
names into IP addresses.

5. • The Domain Name System also specifies the
technical functionality of this database
service. It defines the DNS protocol, a detailed
specification of the data structures and
communication exchanges used in DNS, as
part of the Internet Protocol Suite.

6. • The domain name always contains two or
more components separated by periods,
called dots.
• Some examples of domain names are :
riiit.com,inl.net,nasa.gov,tcs.co.in

7. The major categories for top-level domains are:
• Com- Commercial entities
• Edu- educational institutions
• Net- Organizations directly involved in internet
operations .
• Gov- United States federal government
entities.

8. WEB SERVER
• Web servers are computers that deliver (serves
up) Web pages. Every Web server has an IP
address and possibly a domain name. For
example, if you enter
the URL http://www.pcwebopedia.com/index.ht
ml in your browser, this sends a request to the
Web server whose domain name
ispcwebopedia.com. The server then fetches the
page named index.html and sends it to your
browser.

9. • Any computer can be turned into a Web
server by installing server software and
connecting the machine to the Internet. There
are many Web server software applications,
including public domain software from NCSA
and Apache, and commercial packages
from Microsoft, Netscape and others.

10. WEB PAGE
• A web page or webpage is a document or
information resource that is suitable for
the World Wide Web and can be accessed
through a web browser and displayed on
a monitor or mobile device.
• This information is usually in HTML format,
and may provide navigation to other web
pages via hypertext links.

11. • The web server may restrict access only to a
private network, e.g. a corporate intranet, or it
may publish pages on the World Wide Web.
Web pages are requested and served from
web servers using Hypertext Transfer
Protocol (HTTP).
