Advantages of Computer Communications

Computer communications is playing an increasingly important role not only in offices but also in schools, libraries, and homes. People are realizing that sending and receiving information electronically offers several advantages:

1. Fast, accurate, and direst exchange of information. Sending and receiving data electronically takes only a fraction of the time needed to send it by mall or messenger. And since the information goes directly to the receiver, the sender doesn't have to worry about lost packages or incorrectly addressed envelops.

2. Rapid information processing. Computers can sort or search through huge amounts of information in a flash. Suppose you were a lawyer who needed a history of all court cases involving the theft of governments secrets. How could you get the information? Well, you could go to a law library and search through the reference books. That might take you five hours. You could, instead, use a computer that is electronically linked to a special data bank of legal information. Using that method, you could obtain the information in less that an hour – and never leave your law office!

Exercise 22. Agree or disagree with the following statements:

1. People understand that sending and receiving information electronically offers only difficulties.

2. Sending and receiving data electronically takes only a fraction of time.

3. Computers can sort information in a flash.

4. Computers are electronically linked to a special data bank of information.
