Read the following passage and mark the letter A, B, C, or D to indicate the correct answer.
The advent of the Internet may be one of the most important technological developments in recent years. Never before have so many people had access to so many different sources of information. For all of the Internet’s advantages, however, people are currently becoming aware of some of its drawbacks and are looking for creative solutions. Among the current problems, which include a general lack of reliability and numerous security concerns, the most crucial is speed.
First of all, the Internet has grown very quickly. In 1990, only a few academics had ever heard of the Internet. In 1996, over 50 million people used it. Every year, the number of people with access to the Internet doubles. The rapid growth has been a problem. The computer systems which run the Internet have not been able to keep up with the demand. Also, sometimes, a request for information must pass through many routing computers before the information can be obtained. A request for information made in Paris might have to go through computers in New York, Los Angeles and Tokyo in order to obtain the required information. Consequently, the service is often slow and unpredictable. Service also tends to be worse when the Internet is busiest - during the business day of the Western Hemisphere - which is also when companies need its service the most.
Some people are trying to harness the power of networked computers in such a way as to avoid this problem. In 1995, a group of American universities banded together to form what has come to be known as Internet II. Internet II is a smaller, more specialized system intended for academic use. Since it is more specialized, fewer users are allowed access. Consequently, the time required to receive information has decreased.
Businesses are beginning to explore a possible analogue to the Internet II. Many businesses are creating their own “Intranets”. These are systems that can only be used by the members of the same company. In theory, fewer users should translate into a faster system. Intranets are very useful for large national and international companies whose branches need to share information. Another benefit of an Intranet is an increased amount of security. Since only company employees have access to the information on the Intranet, their information is protected from competitors.
While there is little doubt that the Internet will eventually be a fast and reliable service, industry and the academic community have taken their own steps toward making more practical global networks.
With which of the following conclusions would the author probably agree?
A. Fewer academic communities need to create their own Internet systems
B. An Internet system with fewer users would be quicker
C. The technology used by Internet creators is too complex for computer owners to understand
D. Companies who develop their own Intranets are limiting their information data base
D
Với những kết luận nào sau đây tác giả có thể đồng ý?
A. ngày càng ít các cộng đồng học thuật hơn cần tạo ra các hệ thống Internet riêng của họ.
B. Một hệ thống Internet với ít người dùng sẽ nhanh hơn.
C. Công nghệ được sử dụng bởi người sáng tạo Internet là quá phức tạp để chủ sở hữu máy tính hiểu.
D. Các công ty phát triển Intranet của riêng họ đang hạn chế cơ sở dữ liệu thông tin của họ.
Thông tin ở đoạn cuối: Another benefit of an Intranet is an increased amount of security. Since only company employees have access to the information on the Intranet, their information is protected from competitors.
Tạm dịch:
Một lợi ích khác của Intranet là tăng cường bảo mật. Vì chỉ nhân viên công ty mới có quyền truy cập vào thông tin trên Intranet, thông tin của họ được bảo vệ khỏi các đối thủ cạnh tranh.
