Ex.5. Case-study: Electronic mail – offices on the run.

Marc Silag spends most of his time traveling from one concert to the next. His clients include such celebrities as Paul Simon and Patti Labelle.

Silag’s heavy travel schedule makes it difficult for him to work at a traditional office. But with the help of electronic mail, he can send information to people at his office and other offices by using his computer, a modem, and any telephone. E-mail is a method of electronic communications where information sent is filed on a computer until the recipient is ready to receive it. Each person who uses the system is given an electronic mailbox. Any messages received are filed in the electronic mailbox.

E-mail messages can be sent at any time – 24 hours a day. Silag can send his supervisor important information about a future concert when he ends his day at 2:00 a.m. instead of waiting until the next morning. All Silag has to do is dial the phone number of his office’s computer system and address his message to his supervisor’s mailbox. Then he can go to sleep without worrying about calling the first thing in the morning. The next morning when his supervisor goes to the office, she can read and act on Silag’s message. If there is an answer, Silag can read it when he picks up his e-mail messages.

1. If e-mail had been available in 1862, how might it have changed the lives of the farmers during the agricultural era?
2. If Mark Silag had lived in 1925 and been a production manager for celebrity Rudy Vallee, how might his job have been different?
3. A new communication system that has recently been introduced will allow you to communicate through radio waves instead of telephone lines. With this system, you can send messages from a specially equipped computer without connecting it to a modem and a telephone. What changes might this new system make in Marc Silag’s daily schedule and his method of communicating with his office?
