Just as the trends of the 1980s were difficult to predict, so, too, are the forces that will drive the industry in the 1990s. But by looking at the trends of today, people are able to predict what the industry may look like in the new decade.
Hardware will become a commodity while software and service will account for a greater share of computer companies' revenue, say market watchers. And growth in sales of special systems will come to a halt in the '90s.
As more computer systems are based on such emerging standards as the Unix operating system, customers can pick and choose the best components from different vendors rather than relying on one supplier for complete computer systems. That will accelerate demand for service--rather than products--from vendors. It's the service, the support and the software that add all the value. The move to distributed computers linked by local area networks is increasingly becoming an alternative to centralized computers. A survey of 50 Fortune 1000 companies found that 72 per cent were replacing their minicomputers with personal computer networks. Some trends in the peripherals (外部设备) arena in the next decade are obvious--smaller, quicker, more features. But manufacturers of monitors, printers and disk drives will be looking beyond the computer industry toward future markets that hold vast sales potential.
The automobile industry, for example, holds promise for peripherals vendors. It's very likely in the next five to ten years we'll see vehicles targeted at business executives with printers and fax (传真) machine capabilities built in.
The main idea of the passage is about ______.
A．the trends of the 1990s in computer industry
B．the accelerating demands for software and service
C．computers industry's close link with auto-industry
D．the trends in the peripherals arena in the next decade
