3. What is Internet?
 Internet is network of Networks.
 Computers connected together are called a network.
 Networks let computers share programs and information
 The Internet is a network of many smaller networks made up of
millions of PCs connected to thousands of servers.

13. Web Server
 Web servers are computer that deliver (serves up) Web
pages. Every Web server has an IP address and possibly
a domain name. Any computer can be turned into a Web
server by installing server software and connecting the
machine to the Internet.
 For example, if you enter the URL
http://www.cybersecurityindia.org/index.html in your browser,
this sends a request to the Web server whose domain name is
cybersecurityindia.org. The server then fetches the page named
index.html and sends it to your browser.

15. A server is basically a
computer
Just like the one you are
using now…..
The only difference is,
it users an operating
System that server
information to the client

16. A webhost is a company or
Person that hosts your contest
On their server(s).
They allow people to
manage your content by
using operating Programs
such as Control Panel.

17. DNS
 DNS Stands for Domain Name Server.
 A Domain Name Service translates queries for
domain names (which are meaningful to
humans) into IP addresses for the purpose of
locating and computer services and devices
worldwide.
An often-used analogy to explain the Domain
Name System is that it serves as the phone book
for the Internet by translating human-friendly
computer hostnames into IP addresses. For
example, the domain name www.example.com
translates to the addresses 192.0.43.10 (IPv4)
and 2620:0:2d0:200::10 (IPv6).

18.  Country code top-level domain
A country code top-level domain (ccTLD) is an
Internet top-level domain generally used or reserved
for a country, a sovereign state, or a dependent
territory.
All ASCII ccTLD identifiers are two letters long, and all
two-letter top-level domains are ccTLDs. In 2010, the
Internet Assigned Numbers Authority (IANA) began
implementing internationalized country code TLDs,
consisting of language-native characters when
displayed in an end-user application. Creation and
delegation of ccTLDs is described in RFC 1591,
corresponding to ISO 3166-1 alpha-2 country codes.

20. A unique identifier… like a phone number with area code
The “+91” is the INDIA’s country code.
The “901” is the providers code. Here it
Is for “Reliance” in Gujarat.

22. The “192” indicates that
this is a class “C” network
The “168” used in conjunction
With the 192 indicates this is
a Private IP address for use
Inside a home or business.
The “22” indicates that
Specific class “C” private
Network number.
The “1” indicates a specific
Device on this network. In this
Case, the router

23. If friends are going to
Text you, they need to
Know your number….
If two computer are
Going to communicate,
They need to be able
to locate each other.
They use the IP address to
Do this. If the IP address is
not similar to theirs, it may
Be a “long distance” chat and
It may require a router….

24. Some are given automatically
When you connect to
a Wi-Fi Hotspot…..
Some are given manually by
A network technician….
Some are provided by your
Internet Service Provider….

25. All network device need an IP address to
Uniquely Identify them.
All Internet traffic is routed using IP addresses.
New network devices likeTelevisions will also
Require their own IP address.
The available numbers are running out and you will
Learn how we deal with this in the next chapter.

26. IP Address
 IP Stands for Internet Protocol.
 An Internet Protocol address (IP address) is
a numerical label assigned to each device
(e.g., computer, printer) participating in a
computer network that uses the Internet
Protocol for communication.
 IP addresses are binary numbers, but they
are usually stored in text files and displayed
in human-readable notations, such as
172.16.254.1 (for IPv4), and
2001:db8:0:1234:0:567:8:1 (for IPv6).

27. IP Address (Contd…)
 There are two types of IP address.
 Dynamic (It changes every time when you connect
with server)
 Static (It remain same every time when you
connect).
 Pattern of IP address as illustrated below:

28. IP Address (Cont.…)
 IP address space allocations globally and delegates five
regional Internet registries (RIRs) to allocate IP
address blocks to local Internet registries (Internet
service providers) and other entities.
 Range of Reserve IP addresses.
◦ 10.0.0.0 – 10.255.255.255
◦ 172.16.0.0 – 172.31.255.255
◦ 192.168.0.0 – 192.168.255.255
 The IP address 127.0.0.1 is reserved for testing the
local machine. It cannot be assigned to any computer
for networking. Similarly, IP address starting with 224
and beyond in the first octect are reserved and
cannot be used.

29. ISP
 An Internet service provider (ISP) is an
organization that provides access to the Internet.
 Internet service providers can be either community-
owned and non-profit, or privately owned and for-
profit.
 Access ISPs directly connect clients to the Internet
using copper wires, wireless or fiber-optic
connections.[1] Hosting ISPs lease server space for
smaller businesses and other people (colocation).
Transit ISPs provide large amounts of bandwidth for
connecting hosting ISPs to access ISPs
