选项

答案     During the past ten years, the technology of computer communications has developed rapidly. As a result, more and more people can share the worldwide information resources and services. With the computer communications, you can get a report from the British Museum within several minutes, book a ticket at home, pay bills with a credit card,  or ... everything.   How can a computer communicate with others? Channels and networks make it realizable.
