Telecommunications
"The sending of information
of any form from one place to another using electronic or light-emitting
media"
Electronic methods of communications have made it
very simple for people and organisations to share data and information,
without the need for physical meetings, often over great distances.
Before the 1980's telecommunications systems used to be monopolised by
state-owned companies, such as British Telecom
In the mid 1980's, de-regulation of the state-owned
companies occured, and a number of small, private telecommunications firms
appeared on the market, offering value-added packages to the customer.
What do telecommunications
enable people to do?
-
Voice communications such as voicemail on cellular telephones,
or just basic communication through telephones.
-
Data communications suc as online transaction processing
in retail, Electronic data interchange, Electronic points of sale in shops

Text and message communications , for example, the sending
of e mails, and bulletin boards on the World Wide Web.

Information retrieval systems, such as news and economic
database services and teletext and ceefax services through the television.
-
Image transmission such as faxing and videoconferencing,
which enables two or more people to hold a 'face-to-face' discussion through
their computer screens.

monitor a number of different properties from one central location, by
connecting its CCTV cameras so that they can be viewed on screens in the
central location.
