Today's modern communication technology is quite advanced. It is optical fibers and lasers, together with the striking improvements in computing that have made such remarkable communication possible. By using the telephone-line with expanded capacity, people can send messages not only in the form of sound but also in written words graphs and even moving pictures on the Internet
