In this work I intend to speak about the new technologies, essentially about my
favourite new technology, the Internet.
I want to inform about the importance of the new technologies such as Internet,
and there impact on our modern society.
I hope you like, and that above all, learn with this work.
The rise of new information and communication technologies – social
networking sites, Internet encyclopaedias, multimedia-sharing facilities and databases –
is said to be ‘ushering in a new era’. While new technology is meant to unlock our
creative potential, bring us together and enlighten us, we also fear it is transforming our
lives for the worse – dumping down culture, destroying relationships and eroding
privacy. Will new technology live up to our greatest expectations or fulfil our worst
fears by transforming how we relate to one another? Do we risk confusing technological
advances with sociological trends? Are we giving technology too much credit?
Let us see one of the most influential technology in the 21st century, the
The Internet is a global network of interconnected computers, enabling users to
share information along multiple channels. Typically, a computer that connects to the
Internet can access information from a vast array of available servers and other
computers by moving information from them to the computer's local memory. The same
connection allows that computer to send information to servers on the network; that
information is in turn accessed and potentially modified by a variety of other
interconnected computers. A majority of widely accessible information on the Internet
consists of inter-linked hypertext documents and other resources of the World Wide
Web (WWW). Computer users typically manage sent and received information with
web browsers; other software for users' interface with computer networks includes
specialized programs for electronic mail, online chat, file transfer and file sharing.
The movement of information in the Internet is achieved via a system of
interconnected computer networks that share data by packet switching using the
standardized Internet Protocol Suite (TCP/IP). It is a "network of networks" that
consists of millions of private and public, academic, business, and government networks
of local to global scope that are linked by copper wires, fiber-optic cables, wireless
connections, and other technologies.
Advantages of the Internet
The Internet provides opportunities galore, and can be used for a variety of things.
Some of the things that you can do via the Internet are:
• E-mail: E-mail is an online correspondence system. With e-mail you can send and
receive instant electronic messages, which works like writing letters. Your messages
are delivered instantly to people anywhere in the world, unlike traditional mail that
takes a lot of time.
• Access Information: The 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’ on the Internet can help you to find data on any subject that you need.
• Shopping: Along with getting information on the Internet, you can also shop online.
There are many online stores and sites that can be used to look for products as well
as buy them using your credit card. You do not need to leave your house and can do
all your shopping from the convenience of your home.
• Online Chat: There are many ‘chat rooms’ on the web that can be accessed to meet
new people, make new friends, as well as to stay in touch with old friends.
• Downloading Software: This is one of the most happening and fun things to do via
the Internet. You can download innumerable, games, music, videos, movies, and a
host of other entertainment software from the Internet, most of which are free.
Disadvantages of the Internet
There are certain cons and dangers relating to the use of Internet that can be
• Personal Information: If you use the Internet, your personal information such as
your name, address, etc. can be accessed by other people. If you use a credit card
to shop online, then your credit card information can also be ‘stolen’ which
could be akin to giving someone a blank check.
• Pornography: This is a very serious issue concerning the Internet, especially
when it comes to young children. There are thousands of pornographic sites on
the Internet that can be easily found and can be a detriment to letting children
use the Internet.
• Spamming: This refers to sending unsolicited e-mails in bulk, which serve no
purpose and unnecessarily clog up the entire system.
History of the Internet
Prior to the widespread internetworking that led to the Internet, most
communication networks were limited by their nature to only allow communications
between the stations on the network, and the prevalent computer networking method
was based on the central mainframe computer model. Several research programs began
to explore and articulate principles of networking between separate physical networks.
This led to the development of the packet switching model of digital networking. These
research efforts included those of the laboratories of Donald Davies (NPL), Paul Baran
(RAND Corporation), and Leonard Kleinrock's MIT and UCLA.
The research led to the development of several packet-switched networking
solutions in the late 1960s and 1970s, including ARPANET and the X.25 protocols.
Additionally, public access and hobbyist networking systems grew in popularity,
including unix-to-unix copy (UUCP) and FidoNet. They were however still disjointed
separate networks, served only by limited gateways between networks. This led to the
application of packet switching to develop a protocol for inter-networking, where
multiple different networks could be joined together into a super-framework of
networks. By defining a simple common network system, the Internet protocol suite, the
concept of the network could be separated from its physical implementation. This
spread of inter-network began to form into the idea of a global inter-network that would
be called 'The Internet', and this began to quickly spread as existing networks were
converted to become compatible with this. This spread quickly across the advanced
telecommunication networks of the western world, and then began to penetrate into the
rest of the world as it became the de-facto international standard and global network.
However, the disparity of growth led to a digital divide that is still a concern today.
Following commercialization and introduction of privately run Internet Service
Providers in the 1980s, and its expansion into popular use in the 1990s, the Internet has
had a drastic impact on culture and commerce. This includes the rise of near instant
communication by e-mail, text based discussion forums, and the World Wide Web.
Investor speculation in new markets provided by these innovations would also lead to
the inflation and collapse of the Dot-com bubble, a major market collapse. But despite
this, the Internet continues to grow.
Worldwide Online Population Forecast
In its "Worldwide Online Population Forecast, 2006 to 2011," Jupiter Research
anticipates that a 38 percent increase in the number of people with online access will
mean that, by 2011, 22 percent of the Earth's population will surf the Internet regularly.
Jupiter Research says the worldwide online population will increase at a compound
annual growth rate of 6.6 percent during the next five years, far outpacing the 1.1
percent compound annual growth rate for the planet's population as a whole. The report
says 1.1 billion people currently enjoy regular access to the Web.
North America will remain on top in terms of the number of people with online
Aside from the complex physical connections that make up its infrastructure, the
Internet is facilitated by bi- or multi-lateral commercial contracts (e.g., peering
agreements), and by technical specifications or protocols that describe how to exchange
data over the network. Indeed, the Internet is defined by its interconnections and
Using various statistics, AMD estimated the population of internet users to be
1.5 billion as of January 2009.
Distribution of the Internet pair world
The prevalent language for communication on the Internet is English. This may
be a result of the Internet's origins, as well as English's role as a lingua franca. It may
also be related to the poor capability of early computers, largely originating in the
United States, to handle characters other than those in the English variant of the Latin
After English (29% of Web visitors) the most requested languages on the World Wide
Web are Chinese (19%), Spanish (9%), Japanese (6%), French (5%) and German (4%).
By region, 40% of the world's Internet users are based in Asia, 26% in Europe,
17% in North America, 10% in Latin America and the Caribbean, 4% in Africa, 3% in
the Middle East and 1% in Australia.
The Internet's technologies have developed enough in recent years, especially in
the use of Unicode, that good facilities are available for development and
communication in most widely used languages.
The Internet allows computer users to connect to other computers and
information stores easily, wherever they may be across the world. They may do this
with or without the use of security, authentication and encryption technologies,
depending on the requirements.
This is encouraging new ways of working from home, collaboration and
information sharing in many industries. An accountant sitting at home can audit the
books of a company based in another country, on a server situated in a third country that
is remotely maintained by IT specialists in a fourth. These accounts could have been
created by home-working bookkeepers, in other remote locations, based on information
e-mailed to them from offices all over the world. Some of these things were possible
before the widespread use of the Internet, but the cost of private leased lines would have
made many of them infeasible in practice.
An office worker away from his desk, perhaps on the other side of the world on
a business trip or a holiday, can open a remote desktop session into his normal office PC
using a secure Virtual Private Network (VPN) connection via the Internet. This gives
the worker complete access to all of his or her normal files and data, including e-mail
and other applications, while away from the office.
This concept is also referred to by some network security people as the Virtual
Private Nightmare, because it extends the secure perimeter of a corporate network into
its employees' homes.
The Internet has made possible entirely new forms of social interaction,
activities and organizing, thanks to its basic features such as widespread usability and
Social networking websites such as Facebook and MySpace have created a new
form of socialization and interaction. Users of these sites are able to add a wide variety
of items to their personal pages, to indicate common interests, and to connect with
others. It is also possible to find a large circle of existing acquaintances, especially if a
site allows users to utilize their real names, and to allow communication among large
existing groups of people.
Sites like meetup.com exist to allow wider announcement of groups which may
exist mainly for face-to-face meetings, but which may have a variety of minor
interactions over their group's site at meetup.org, or other similar sites.
The Internet has been a major source of leisure since before the World Wide
Web, with entertaining social experiments such as MUDs and MOOs being conducted
on university servers, and humor-related Usenet groups receiving much of the main
traffic. Today, many Internet forums have sections devoted to games and funny videos;
short cartoons in the form of Flash movies are also popular. Over 6 million people use
blogs or message boards as a means of communication and for the sharing of ideas.
The pornography and gambling industries have both taken full advantage of the
World Wide Web, and often provide a significant source of advertising revenue for
other websites. Although many governments have attempted to put restrictions on both
industries' use of the Internet, this has generally failed to stop their widespread
One main area of leisure on the Internet is multiplayer gaming. This form of
leisure creates communities, bringing people of all ages and origins to enjoy the fast-
paced world of multiplayer games. These range from MMORPG to first-person
shooters, from role-playing games to online gambling. This has revolutionized the way
many people interact and spend their free time on the Internet.
While online gaming has been around since the 1970s, modern modes of online gaming
began with services such as GameSpy and MPlayer, to which players of games would
typically subscribe. Non-subscribers were limited to certain types of game play or
Many use the Internet to access and download music, movies and other works
for their enjoyment and relaxation. As discussed above, there are paid and unpaid
sources for all of these, using centralized servers and distributed peer-to-peer
technologies. Some of these sources take more care over the original artists' rights and
over copyright laws than others.
Many use the World Wide Web to access news, weather and sports reports, to plan and
book holidays and to find out more about their random ideas and casual interests.
People use chat, messaging and e-mail to make and stay in touch with friends
worldwide, sometimes in the same way as some previously had pen pals. Social
networking websites like MySpace, Facebook and many others like them also put and
keep people in contact for their enjoyment.
The Internet has seen a growing number of Web desktops, where users can
access their files, folders, and settings via the Internet.
Cyberslacking has become a serious drain on corporate resources; the average
UK employee spends 57 minutes a day surfing the Web at work, according to a study by
Peninsula Business Services.
