FAX (facsimile telegraphy): Facsimile telegraphy deals with the transmission of typed or handwritten messages, drawings, graphs, pictures, or any other matter that cannot be sent via telegraphs, telephones, or teleprinters. This machine works by converting the variations of light reflected in the image. of the original matter into electrical impulses that can be reconverted into the image upon reception. Connections can be made over very long distances using public telephone networks or radio links. Fax is perhaps the fastest system available today, and it takes approximately four minutes to transmit and receive a standard letter-size document, regardless of the amount of material it contains. In this system there is no room for copying errors and therefore high level skills in high skills are required. Even typed material can be transmitted more efficiently by fax than by teleprinter, since the former completely eliminates the inadvertent built-in error checking element during transmission of the material.
ELECTRONIC MAIL (E-Mail) – This is also a progeny of computer technology. It facilitates the transmission of messages through the use of computer storage and computer interconnections, thus eliminating postal delays. The message is simply entered into the system. The signals, converted into digital pulses, are stored in the computer’s memory for retrieval. The message can be retrieved at the recipient’s convenience. Therefore, in addition to saving time, email is a more convenient and discreet method of sending a message, since the sender can be sure not to disturb the recipient. In close internal communication, the links are established either by the CPU of the Internet workstations of the computer network. In remote communication between offices in different locations, an extensive network of satellite or microwave technology is used for the transmission of electronic mail. Usually, group communication takes place in person, in the same room, but the new technology provides a facility for discussion with the group of people on the Internet. You can hold a meeting, have a group discussion, or brief people scattered across the country or the world. You can consult various experts through computers using decision support systems to get their point of view before making a decision or finalizing a plan of action. In teleconferences, the focus is on the idea or concept that is being communicated. This is an advantage of the method, but sometimes this excessive emphasis on the message with the corresponding carelessness of the person who communicates it, may not be totally in tune with the corporate culture, which needs a dynamic means of communication.
Teleconferencing: Group communication usually takes place in person, in the same room, but new technology makes it possible to discuss with a group of people on the Internet. You can hold a meeting, hold a group discussion, or brief people scattered across the country or the world. You can consult multiple experts via computers using group decision support systems to get their point of view before making a decision or finalizing a plan of action. In teleconferences, the focus is on the idea or concept that is being communicated. This is the advantage of the method, but sometimes this excessive emphasis on the message with the corresponding carelessness of the person who communicates it, may not be totally in tune with the corporate culture, which needs a dynamic means of communication.
It is an arrangement that makes it easy for speakers to communicate with each other in different locations using public telephone links. The conference participants located in different geographical distance areas can discuss topics using their terminals which are connected to each other, ie the telecommunication network.
In recent years, large business organizations are using the teleconferencing method to conduct business meetings with interested executives who are geographically dispersed in a region. For example, a company that has a chain of branches offers a network for teleconferencing service. Members or participants can go to their local branch and participate, and interact in discussion with the speaker at other branches. It is worth mentioning that an alternative to computer conferences are teleconferences. An electronic link of geographically dispersed people is undoubtedly an oral communication through a medium but without the presence of people. The advantage of face-to-face conversion cannot be gained from teleconferences, which cannot replace them. Body movements, facial expressions that also communicate feelings, attitudes, etc. cannot be seen with the teleconference perfectly. But on the other hand, the teleconference offers a number of advantages such as:
1. Time is saved.
2. Cost and energy are saved.
3. Travel to a distant place to attend the conference is avoided.
4. Without monotony or fatigue.
5. Work arrangements, facilities and accommodation are eliminated.
