Reinforces oral communication;
provides additional visual stimulus;

May be difficult to interpret without
reinforcing written or spoken word;
requires additional skills of comprehension
and interpretation
can be costly and expensive in time to

Local/wide area networks
Fax
Telex
Packet switching
Teleconferencing
Computer conferencing/networking
CT advantages
1.
Speed of transmission: WAN
messages, London to Sydney,
Australia in 11 seconds.
CT advantages
1.
Versatility: Fax can transmit text,
number, graphics, artwork and
photographs all on one side of A4 if
need be. Tele-and computer
conferencing provide interpersonal
exchanges visually and via VDU
screens.
CT adv cont’d
3.
Accuracy Instantaneous message-reading
and checking of electronic circuits operating
between sending and receiving equipment
during the transmission of high-speed ‘bits’
of the message in packetswitching of
computer data ensure the message is
accurately received in remote locations.
CT advantages
3.
Feedback/instantaneous exchange:
Cómputerised telecommunications
allow for a virtually simultaneous
exchange of information and
responses.
CT disadvantages
1.
Volume of transmitted data: The volume of
telecommunicated information is increasing
at such a rate that business personnel are
unable to absorb it within relevant time limits
CT disadvantages
1.
Costs: Telecommunicated messages
have billing premiums placed upon
them to pay for the enormous
development and hardware
investments made nationally and
internationally. However, the cost of
fax, telex and communications modems
etc is falling rapidly in an expanding
market.
CT disad. cont’d
3.
Legal implications: Words printed on
paper at source still have a legal
currency that a faxed message does
not (but which telex does!).
CT disdvantages
3.
Instant delivery: The almost
instantaneous delivery of LAN/WAN
Email messages etc can cause upsets
if messages are composed in anger or
are ‘half-baked’ and then dispatched
irretrievably.
