COMMUNICATION THROUGH ELECTRONIC CHANNELS

Communication

Communication is the activity of conveying information. Communication requires a sender, a message, and an intended recipient, although the receiver need not be present or aware of the sender's intent to communicate at the time of communication• Thus communication can occur across vast distances in time and space.

Communication Cycle

•The first major model for communication came in 1949 by Claude Shannon and Warren Weaver for Bell Laboratories

•The Sender-Message-Channel-Receiver Model of communication separated the model into clear parts

Communication Cycle consists of –

• An information source, which produces a message.• A transmitter, which encodes the message into signals• A channel, to which signals are adapted for

transmission• A receiver, which 'decodes' (reconstructs) the

message from the signal.• A destination, where the message arrives.

the Communication Channels

• A channel is used to convey an information or signal, that is destined to communicate from one person to the other

e.g. Digital Bit stream

• The channels communicate the information from one or several senders (or transmitters) to one or several receivers.

• A channel has a certain capacity for transmitting information, often measured by its bandwidth in Hz or its data rate in bits per second .

• The beginning of human communication through artificial channels, i.e. not vocalization or gestures, goes back to ancient cave paintings, drawn maps, and writing.

History of communication channels….

Dominant communication medium divides history into the following stages:

(i) IDEOGRAPHIC WRITING produced the first civilization, the alphabetic writing,

(ii) The second PRINTING .(iii) The third ELECTRONIC Recording and Broadcasting, (iv) The fourth and COMPUTER COMMUNICATION, (v) The fifth MOBILE DEVICES, involves ad-hoc

organization through, allowing for effective many-to-many communication and SOCIAL NETWORKING.

“The last 3 categories are grouped together as Electronic channels “

The Telecommunication

• A revolution in telecommunications provide new media for long distance communication.

• Analog telecommunications include traditional telephony, radio and TV broadcasts.

• Digital telecommunications allow for computer-mediated communication, wireless communication technology and computer networks.

The TechnologiesFAX

–While there is a lot of attention focussed on using computers to send and receive documents, the stand-alone fax machine is an important electronic communication channel–Broadcasting or

polling can be used to send faxes to hundreds of clients or prospects

TELEPHONE• Telephone Technology for small

Businesses– Sophisticated Multiplex

telephone-systems capable of supporting many lines and advanced features are often expensive and therefore out of reach for many small businesses.

• Three Way Calling– Three-way calling allows you to

link three people into one conversation

– . It saves time by exchanging information with more than one person concurrently.

•

• Toll Free Calling services– Providing your clients with access to a toll-free

number tells them that you are ready to do business regardless of where they are located

– This type of service can be very beneficial if a significant number of your clients and business associates are located outside your local area.

PAGERS

• Pagers–These are smaller,

provide better coverage and provide increased flexibility.–A pager is especially

practical if you have employees who are always on the go.–Some firms use

pagers to locate employees within their own building.

Wireless Communication Tools

• Cellular Phones –– Cellular telephones are an excellent tool that provide

you with mobility, accessibility and flexibility.– Cellular telephones also enables clients to maintain

contact without having to dial several numbers. This makes you more accessible

– Short Messaging Service is another channel of communication which is faster, reliable and prevents the loss of data which can occur in voice calls

– Value Added Services are provided by cellular service providers which help to navigate, check travel status etc.

WIRELESS EMAIL

• Wireless email– If e-mail is essential and you spend a lot

of time on the road, wireless technology enables e-mail access when you are away from the phone.

– This technology allows you to check your mail from a parked car, hotel room or even while on the beach!

Mobile phones

Mobile phones mark up a new era for communication technology . Now a days the 3 –G services are also found which have changed the face of mass communication very strongly . Nobody is nowhere alone in this world …

Few examples of usage of mobile phones in our life

Radio• Although its business uses are limited,

radio is an effective means of broadcasting information to many people at once

• Radio and other forms of mass communication do not allow for convenient, prompt feedback.

• The most common business use of radio is for advertising, primarily at the local level.

• The advantages of radio are that it is a relatively inexpensive medium for both sender and receiver, and messages may be prerecorded for a later broadcast.

• The disadvantages are the absence of a convenient means of feedback and more attention is paid to information chanelled through other tools of electronic communication.

Television

• Television, another of the mass media, is also an effective means of broadcasting information to many people at once.

• . Because it combines auditory and visual images, TV provides a fairly effective substitute for face-to-face communication when time, distance, or cost of travel would make face-to-face communication difficult.

• The advantages of television—video—are that it combines both audio and visual information in a way that approximates face-to-face communication

• Messages may be prerecorded and checked to ensure that they communicate the intended message before delivery at a later time.

• The principal disadvantage of television is that it is expensive, especially when it is done well.

• Recording and broadcasting equipment are expensive. Recording, duplicating, and distributing videotapes (or DVD disks) is also expensive,

• Broadcast quality video requires good cameras, trained operators, and usually a trained producer. Those who will be on camera require sufficient training

Emails

• Email has recently become the most common form of business communication, substituting for letters, memos, and many telephone calls.

• The advantages of email are that it is both quick and convenient. It can be printed, saved electronically, or forwarded to multiple recipients.

• Email provides enhanced features; such as file attachments, Rich Text Format, and delivery confirmation etc., which is otherwise not possible when sending a normal letter.

• Email Lists simplify the process of exchanging information with groups of people who share common interests.

• The disadvantages of email are that because speed often seems more important than correctness, email messages often contain egregious errors in spelling, grammar, mechanics and content

Computer Telephone Integration

• Computer-Telephone Integration is another new and emerging technology which combines computers, conventional telephone sets, and the Internet through the use of special software.

• It includes the following channels-• Audio conferencing• Videoconferencing• Web conferencing• Social Networking

Web conferencing

The web conferencing is the most common method for holding the meeting now a days . This is as effective as talking face to face but involves the freedom from hustle of travelling.

Social networking sites

• Social networking sites are a new hub of social interaction between people . Various sites like facebook , twitter and orkut are most popular ones among many.
