四  阅读理解

 

The output is the last step in computer operation. It changes the computer’s results from binary machine language into a form that people can understand. There are several kinds of output devices.

Suppose a shoe store owner wants to know which style of shoe is selling best. He uses a printer. It actually prints, or types, the numbers of shoes sold on a long strip of paper. The machine printout shows him which shoes he should order. High-speed printers can print an entire ling at the same time turning out as many as twenty thousand lines a minute.

A city planner, though, may use her computer in a different way. She wants to plan a new bus route to serve the largest number of people. Using a plotter as the output, she gets a drawing, actually a map, showing the route chosen by the computer.

The telephone operator who looks up telephone numbers uses a computer. But she does not need a printed copy, nor a drawing of the number. Therefore, she has a computer terminal with a CTR .the screen flashes the number of a little while, and then it disappears, ready for the next request.

Computers vary considerably in size, capability and type of application. Each type of a computer operation requires a different type of operating system. “What is an operating system?" It can be answered at several levels.

Firstly, an operating system is a program, or set of programs. Operating systems vary in size from very small to very large, but all are pieces of software.

Secondly, an operating system is, by virtue of its name, a system.

      Thirdly, a computer may be regarded as a set of devices, or resources, which provide a number of services, such as input, processing, storage and output. The operating system of the computer may be regarded as the manager of these resources. It controls the way in which these resources are put to work..

Finally, an operating system is the lowest layer of software on a computer. It acts directly on the hardware of the computer. It supports other layers of software such as compilers and applications programs.
