Passage 2
什么是賽百空間(cyberspace)?按約翰·帕利·巴洛的說法，賽百空間可以最言簡意賅地定義為“你利用電話進行交談時所處的空間”。 當然, 賽百空間之所云比打電話更廣泛。它包括數以百萬計的計算機用調制解調器通過電話系統相連形成的聯網商業服務系統， 它接入當地高速信息網絡、辦公電子郵件和國際互聯網之中。它包括發展迅速的無線服務系統：負責大量的手機信號與數據傳輸的微波發射塔;連珠似的運行于地球同步軌道上的通訊衛星;象怒蜂一樣穿梭往返于地球與太空之間的低空衛星，它們把用線路聯絡顯得太遠或花費太多的人們聯原來的電纜線，利用光纜和高速轉換器建成的那種所謂的全方位服務網絡那樣。
Cyberspace, of course, is bigger than a telephone call. It encompasses the millions of personal computers connected by modems via the telephone system to commercial online services, as well as the millions more with high - speed links to local area networks, office E-mail systems and the Internet. It includes the rapidly expanding wireless services: microwave towers that carry great quantities of cellular phone and data traffic; communications satellites strung like beads in geosynchronous orbit; low - flying satellites that will soon crisscross the globe like angry bees connecting folks too far - flung or too much on the go to be fastened by wires. Someday even our television sets may he part of cyberspace, transformed into interactive teleputers" by so- called full- service networks like the ones several cable - TV companies are building along the old cable lines, using fiber optics arid high speed switches.
