i) Fax --refers to a system of transmitting exact copies of documents quickly and accurately over telephone lines to another fax terminal. The documents are transmitted through the facsimile transmission which converts digital signals to analogue for telephone transmission and back to digital via in-built fax modems.

ii) Telex- is a machine which resembles a typewriter with a telephone dial. It is capable of reproducing messages transmitted from a distant teleprinter over telephone lines, thus combining the speed of a telephone with the authority of the written word. The printed copy of the messages is produced on telex at both the sending and receiving subscribers? installations. Calls may be made to any telex subscriber within the country or abroad.

iii) Electronic mail- is the term used to describe a range of electronic transmission services but is commonly applied either to a company?s mailbox system operated via its own computer or to one of the services providers.

iv) A teleconference is a telephone or video meeting between participants in two or more locations. Teleconferences are similar to telephone calls, but they can expand discussion to more than two people. Using teleconferencing in a planning process, members of a group can all participate in a conference with agency staff people. Teleconferencing uses communications network technology to connect participants? voices. In many cases, speaker telephones are used for conference calls among the participants. A two-way radio system can also be used. In remote areas, satellite enhancement of connections is desirable.
