Different types of E.Communication

developments of the late 20th century.

It is probably the most important telecommunication break-through in recent times.

Cont’d…..

Cellular phones give all the benefits of an ordinary fixed phone, but with extra flexibility, mobility, security and whole range of new services, with cellular phone, one can call anywhere and can be reached from any telephone in the world.

The cellular telephone network is divided into cells, each one controlled by a radio base station

Pager....

A pager:- is a small telecommunications device that receives (and, in some cases, transmits) alert signals and/or short messages. This type of device is convenient for people expecting telephone calls, but who are not near a telephone set to make or return calls immediately.

Fax:-An image of a document made by electronic scanning and transmitted as data by telecommunication links.

E-mail - This is similar to private messaging through social

networking, but is certainly more formal.

They can be forwarded and sent to as many contacts that you wish.

The message is typed on a computer screen at one end, and is conveyed to the other end through electric impulses.

.

The person operating the computer terminal at the receiving end is alerted by a signal that a message or mail, inevitable for him is in the electronic mailbox or he can frequently see his mailbox to check for any incoming mail

Advantages of E-mail

It is the quickest means of transmitting messages. It saves you from telephone tags. E-mail messages are supposed to be highly secure and secret. E-mail can be sent to a large number of people simultaneously.

FAX (Facsimile or duplicate, reproduce Telegraphy) - Facsimile telegraphy deals with the transmission of typewritten or handwritten message drawings graphics

pictures or any matter which cannot be sent through telegraphs , telephones or teleprinters.

effectively through fax .

VICTIMS…

Most of the victims of virtual reality in Russia are

CHILDREN AND TEENAGERS

Text message - We are all aware of the uses of text messaging. They are short and a good way to communicate short bits of information that can be received and replied at their own leisure(free time). A recent statistic showed that 91% of Americans that have a mobile keep it within 3 feet of them at all times.

Video conferencing - This gives greater information by the fact that both parties can see each other. Physical contact is missing but Estate Agents are still able to see body language and facial expressions. Used less often, but perfect for staff meetings in different geographical locations.

Face to Face - The greatest type of communication face to face. The physical contact provides both parties with information that they wouldn't have previously known and let's people give a much better sense of each

Telephone - The telephone is even more personalised that the channels previously mentioned. The telephone instantly allows both parties to hear the tone and emotions and is possibly the most used communication tool with Estate Agents.

Teleconferencing - Usually, group communication takes place in person, in the same room, but new technology provides a facility for discussion with a group of persons on the internet.

You can conduct a meeting, hold a group discussion or brief people spread across the country or around the World.

You can talk to a number of experts through computers using group decision support systems for their views before making a decision or for finalizing a plan of action.

Contd…..

In recent years, big business organizations are using teleconferencing method to conduct business meetings with the concerned executives

Advantages of teleconferencing

Time is saved. Cost and energy are saved.  Travel to distance place to attend conference is

avoided. The work arrangements , facilities, and

accommodation is eliminated 

Internet It is a global collection of people computers linked together by telephone lines, radio links or satellite links.

Internet is a network of computers worldwide which allows its users to share information.

Apart from the E-mail service of the internet, with which most people are familiar, the World Wide Web (WWW) is the latest vehicle of business now available on the internet.

introduced, they were little better than glorified(overestimated) calculators. Today's high-end machines have the same functionality as desktop computers, including Internet access that permits the use of various communications tools such as instant messaging, email and video conferencing. Popular models are manufactured by Dell, Apple, Gateway and Toshiba

Twitter is a popular social networking site created in 2008. While the concept is not unlike similar social sites such as MySpace and Facebook, Twitter is unique in that users can write (or "tweet") messages from either their computer or cell phone in short, concise updates, as often as they please. The concept of Twitter revolves around the idea that people can stay updated on the events of others' lives without spending a lot of time.

Paging started a bit late in India. In India, paging and cellular services started almost at the same time.

Paging is the quickest way to communicate today. Paging is a one-way wireless communication facility by which one can stay in touch with anyone - clients, office or family, when one is on the move.

If someone needs to contact a subscriber urgently, all that he has to do is pick up the phone and dial the pager number of the subscriber to leave a message. The message is immediately transmitted to the subscriber on his pager, wherever he is. Giving the subscriber direct access to the information he needs.
