节流阀和调速阀的区别:帮忙翻译一段小文章，多谢

Managers have always used information to perform their tasks, so the subject of management information is nothing new. What is new is the recent availability of better information. The innovation that makes this possible is the electronic computer.
The computer is a relatively new tool, since it became popular only about twenty-five years ago. It was first applied to business tasks mainly as an accounting tool. More recently, the value of the computer as a producer of management information has been recognized. The term management information system (MIS) is by now quite popular, and all firms have some type of MIS.
The information systems of some firms are better than those of others. And some systems are computer-based, whereas others use keydriven machines, punched card machines, or manual methods. These two differences do not necessarily relate to each other; the better systems are not always the computer-based ones. The quality of the MIS is determined by the people who design it—the managers and computer professionals—not by the type of equipment.
The control over information that MIS designers have is called information management. The manager can use information as another resource. A body of knowledge has been assembled that describes how information can, and should, be managed. The objective of part one is to introduce the topic of information management.

Importance of information management
Interest in information management has increased during recent years—both in the college classroom and in the world of business. Two main reasons account for this: the increasing complexity of the management task and improved decision making tools.
