FAX (Facsimile 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.This machine operates by converting the variances of light reflected from the image of the original matter into electrical impulses which can be reconverted onto the image from on reception . Connections can be made over very long distances using the public telephone networks or radio links. Fax is perhaps the speediest system presently available and transmitting and receiving a standard letter size document takes approximately four minutes, irrespective of the amount of matter on it. In this system there is no scope for copying errors and so high order skills required at high skills. Even typed matter can be transmitted more effectively through fax than through the teleprinter since the former completely does away with the hoodia España element of checking for errors inadvertently incorporated during transmittal of the matter. ELECTRONIC MAIL (E-Mail) ? This , too is a progeny of computer technology. It facilities the transmittal of messages through the use of computer storage and computer inter-links , thus eliminating postal delays. The message is simply keyed 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. Thus apart from being time saving , electronic mail is a more convenient and unobtrusive method of sending a message as the sender can be sure of not disturbing the recipient. In close inhouse communication, links are established either by the CPU of computer network internet workstations. In distant communication between offices at different locations , an extensive network of microwave or satellite technology is used for the transmission of electronic mail.
