The document discusses communication and the evolution of communication technologies. It begins by defining communication and describing how communication has developed from early pictographs through written language to modern electronic communication using electromagnetic waves. It then discusses how technology has impacted society by enabling advanced economies but also environmental issues. New technologies often raise ethical issues and influence social values. The document also defines social networks and networking websites, and discusses both the advantages of staying connected with others and interacting, as well as the disadvantages such as security risks, loss of productivity, and potential legal issues from inappropriate content.

1. Techno World
Communication (from
Latin communicate, meanin
g "to share" [1]) is the
activity of
conveying information thro

the use of pictographs. The pictograms were
made in stone, hence written communication
was not yet mobile.
 The next step occurred when writing began to
appear on paper, papyrus, clay, wax, etc. with
common alphabets Communication became
mobile.
 The final stage is characterized by the transfer of
information through controlled waves
of electromagnetic
radiation (i.e., radio, microwave, infrared) and
other electronic signals

3. Technologies

Technology has affected society and its
surroundings in a number of ways. In
many societies, technology has helped
develop more advanced
economies (including today's global
economy) and has allowed the rise of
a leisure class. Many technological
processes produce unwanted byproducts, known as pollution, and deplete
natural resources, to the detriment of
Earth's environment. Various
implementations of technology influence
the values of a society and new
technology often raises new ethical
questions. Examples include the rise of
the notion of efficiency in terms of human
productivity, a term originally applied only
to machines, and the challenge of
traditional norms.

4. Social Network
A social network is a social
structure made up of a set
of social actors (such as
individuals or organizations) and a
set of the dyadic ties between
these actors. The social network
perspective provides a set of
methods for analyzing the
structure of whole social entities
as well as a variety of theories
explaining the patterns observed
in these structures .The study of
these structures uses social
network analysis to identify local
and global patterns, locate
influential entities, and examine
network dynamics.
