The document discusses the history and impact of the internet. It describes how the internet began with the development of computers in the 1950s and early computer networks like ARPANET. It then outlines some key advantages and disadvantages of internet use, such as faster communication, access to vast information resources, entertainment options, and risks like viruses and theft of personal information. Finally, it argues that the internet has fundamentally changed human life and development in a way that it has become essentially obligatory for modern society.

Internet?

3.  The Internet is a global system of interconnected
computer networks that use the standard Internet
protocol suite (TCP/IP) to link several billion devices
worldwide. It is an international network of networks that
consists of millions of private, public, academic, business,
and government packed suitched networks, linked by a
broad array of electronic, wireless, and optical networking
technologies. The Internet carries an extensive range of
information resources and services, such as the inter-
linked hypertext documents and applications of the World
Wide Web (WWW), the infrastructure to support email,
and peer-to-peer networks for file sharing and telephony.

4.  The history of the Internet begins with the development of electronic
computers in the 1950s. Initial concepts of packet networking originated in
several computer science laboratories in the United States, Great Britain,
and France. The US Department of Defense awarded contracts as early as
the 1960s for packet network systems, including the development of the
ARPANET (which would become the first network to use the Internet
Protocol.) The first message was sent over the ARPANET from computer
science Professor Leonard Kleinrock's laboratory at University of California,
Los Angeles (UCLA ) to the second network node at Stanford Research
Institute (SRI).
 Packet switching networks such as ARPANET, Mark I at NPL in the UK
, CYCLADES, Merit Network, Tymnet, and Telenet, were developed in the
late 1960s and early 1970s using a variety of communications protocols. The
ARPANET in particular led to the development of protocols for
internetworking, in which multiple separate networks could be joined into a
network of networks.

5.  The Internet offers a lot of advantages of modern man, who facilitates or improve
his life or helps to save time, money or gives ways to spend time feeling better (at
least for now), etc. Unfortunately, however, use of the Internet presents certain
problems, dangers, which is very good for anyone who accesses the Internet to
know, to realize, and to beware of them.
 Advantages
1. Faster Communication:
The foremost target of Internet has always been speedy
communication and it has excelled way beyond the
expectations. New innovations are only going to make it
faster and more reliable. Now, you can communicate in a
fraction of second with a person who is sitting in the
other part of the world. With the help of such services, it
has become very easy to establish a kind of global
friendship where you can share your thoughts and
explore other cultures.

6.  Information Resources
Information is probably the
biggest advantage that
Internet offers. Internet is a
virtual treasure trove of
information. Any kind of
information on any topic
under the sun is available on
the Internet. The search
engines like Google, Yahoo
are at your service on the
Internet. There is a huge
amount of information
available on the Internet for
just about every subject
known to man, ranging from
government law and
services, market information,
new ideas and technical
support. Today, it is almost
required that students should
use it for research or the
purpose of gathering
resources.
 Entertainment

Entertainment is another
popular reason why many
people prefer to surf the
Internet. In fact, the
Internet has become quite
successful in trapping the
multifaceted entertainment
industry. Downloading
games or just surfing the
celebrity websites are
some of the uses people
have discovered. Even
celebrities are using the
Internet effectively for
promotional campaigns.

7. Social Networking
Online Services
The Internet has made life very convenient.
With numerous online services you can now
perform all your transactions online. You
can book tickets for a movie, transfer
funds, pay utility bills, taxes etc., and right
from your home.
One cannot imagine an online life without
Facebook or Twitter. Social networking has
become so popular amongst youth that it
might one day replace physical networking. It
has evolved as a great medium to connect with
millions of people with similar interests. Apart
from finding long-lost friends, you can also look
for a job, business opportunities.

8.  Disadvantages
 Virus Threat
Theft of Personal Information
If you use the Internet for online banking, social
networking or other services, you may risk a theft to
your personal information such as name, address,
credit card number etc. People can access this
information through unsecured connections or by
planting software and then use your personal details
for their benefit. Needless to say, this may land you in
serious trouble.
Internet users are often plagued by
virus attacks on their systems. Virus
programs are inconspicuous and may
get activated if you click a seemingly
harmless link. Computers connected
to the Internet are very prone to
targeted virus attacks and may end up
crashing.

9.  Social Disconnect
Thanks to the Internet, people now only meet on social
networks. More and more people are getting are drifting
apart from their friends and family. Even children prefer to
play online games rather than going out and mingling with
other kids.
With all its falls the internet has the potential to make your
life simple and convenient, as well as wreak havoc in your
life. Its influence is mostly dictated by the choices you make
while you are online. With clever use, you can manage to
harness its unlimited potential.

10.  In essence, the Internet has changed our lives, the way to
communicate, how to make business, the way to pay taxes, how to
make shopping, the way scientific research is done. Evolution of
mankind is unthinkable without internet.
 The existence of mankind as we know it today is unthinkable without
internet.
 I am convinced that humanity could survive a possible disaster that
would destroy the Internet, but any development would lead to a
system like the Internet.
 The fact that the internet exists is a phenomenon with the probability of
happening equal to 1 , it could be interpreted as the emergence of the
Internet is mandatory to happen somewhere in the evolution of our
society.
 Yes, I could physically survive without internet, but I would have a
lesser life, knowledge and experience. My opinion is that a modern
man in the 21st century (that is not living in a cave) needs the internet
obligatory
