FACSIMILE MACHINES

Can you imagine putting a piece of paper into a copy machine and having the copy turn up in an office halfway around the world? That is what facsimile (fax) machines do. A one-page letter can be sent coast-to-coast in 20 to 30 seconds for about 30 cents. This is probably the fastest-growing communications innovation in industry today. These machines enable you to send a letter or longer document to someone and have that person receive it immediately. They can also act as desktop copiers.

There are portable fax machines available for your car. PayFAX machines are like phone stations that hang on the wall You use a PayFAX like a pay phone from 20, 000 units in cities around the world. A recent twist in fax technology is fax-back. Callers simply indicate what information they want from a company - a sales brochure, for example - by pushing keys on their phones. They then key in their fax numbers, and the data is on its way.

In 1990. Star Signal introduced the first fax machine that can send full-colour pictures. The next generation of fax machines is expected to be the cordless fax. Like the wireless computer, the cordless fax will use radio waves.

Fax modems are modems that allow you to send messages from your computer to other peoples fax machines. Most people find it easier to use a stand-alone fax machine, however. The most limiting feature of a fax modem is that you can only send data you have on file in your computer. If you want to send a printed document that is not on your computer using a fax modem, you must either enter the data by hand by keying it in from the keyboard or by scanning the document with an optical scanner (a device that translates printed material so a computer can understand and manipulate it).

ELECTRONIC MAIL (E-MAIL)

Electronic mail is a means of sending and receiving messages-internally, nationally, or internationally.

Subscribers to e-mail need a terminal, such as personal computer, a telephone line, and a modem, which is a device for converting signals to text. Messages appear on the receiver's computer screen. E-mail users can also have access to a mailbox, which they can call from anywhere in the world and retrieve messages. They receive a mailbox number and a password for confidentially. Messages can be printed out and kept for reference.

In comparison with telex, e-mail is relatively low in cost, and does not require a trained operator. It is also fast, relatively reliable, and messages can be sent or picked up anywhere in the world, and stored in the mailbox until they are retrieved.

This can be particularly advantageous for users who are communicating across international time zones.
