1. Convergence of Computers,
Communication and Content
Chapter 1 (IX)

2. • Today we are all living in a truly digital world,
made up of binary digits (bits), that is, 0s and 1s
of the digital language. Any form of
communication that we can think of today-
mobile or landline telephones, SMS messages,
emails, FM radio broadcasts, satellite TV
channels, Internet-all have these streaming bits
at the core.
• Today new techniques of information packaging
and delivery ensure it is made available
anywhere instantly. The exploiting technologies
provided by telecommunications, computer
networking and broadcasting media. This has led
to an emergence of the information society.

3. Information Society
• An information society (also called wired
society) is the one, which is wired or
networked. This has enabled electronic
communication becoming an integral part of
our personal and work lives.
• Now, the people are acquainted with emails,
videoconferencing and mobile phones, that
too at a very minimal cost.

4. Convergence of Computers and
Communications
• Today with the convergence of computers and
digital communication this old model of a single
large computer is replaced by a large number of
separate but interconnected computers that are
easy to access. This interconnection of
independent systems is called computer network.
• Ex: exchanging emails, file transfer, remote login,
accessing information over websites, Internet
telephony, videoconferencing, multimedia, e-
commerce, e-learning, e-banking and so on.

5. Convergence and Multimedia
• The convergence of content with computers and
digital communication has resulted in the
emergence of multimedia. It is the mixing of
different media on a computer screen in a form
with which the user can communicate
interactively. The different types of media that
can be mixed are text, sound, graphics, animation
and video.
• Two people of different part of the world can play
the game against each other via internet.

6. Convergence of 3Cs Over Mobile
• Today the mobile phone users are demanding to
get more data and even video on the cellular
mobile telephone. The convergence of 3Cs over
mobile has been made possible by what is called
3G or the Third Generation wireless system.
• GPRS (General Packet Radio Service) is the first
move towards implementing 3G networks.
• Bluetooth is a new dimension in wireless
communication to connect spontaneously to
each other without wires.

7. Major Value Added Services
• Email
• Internet access over cable
• E-commerce
• E-learning
• E-governance
• E-banking
• Radio and television broadcast over Internet
• Videoconferencing using Internet
• Internet telephony with live video
• Voice based navigation by GPS (Global Positioning
System) device in cars.

8. Security Issues because of convergence
• With Internet becoming the backbone of activities,
issues of protecting information has become critical.
Some of the technologies deployed for security are:
• Employing various layers of security
• Cryptography
• Access-control
• Activating firewalls
• Installing secure web servers
• Measures to provide legal protecting to electronic
transactions: digital signature, digital certificates,
stringent cyber laws

9. Emerging Trends Because of 3Cs
Convergence
• Real time navigation
• Tele-medicine
• Tele geoprocessing application
• Crisis management applications
• Virtual laboratory
