Ex. 5 Read and translate the text:
Computer networks
1. Network is the term that is used to describe at least two but usually more communication devices connected to each other. There are two common categories of networks with which everyone is familiar. The first category is a network that broadcasts information from a single source. Radio and television networks are an example: a group of stations are linked together so that the same programs can be carried to a wider audience.
2. The second category is a network that transfers information among many sources. A telephone system is the prime example: the focus is input oriented -that is - switching messages from one location to another. In a computer example, the manager of a department is preparing a pay raise report by using the personal computer on her desk. The manager needs to know the start date and current salary of all employees in the department. By using a decentralized network, she communicates to a mainframe computer in which payroll records are kept and incorporates those data into the report. Then, she sends electronic messages to each employee in the department, asking for updated job descriptions to incorporate into the report. By using a network of computers, the manager is able to produce and distribute a more effective and accurate report, and do it much faster than if it had been done manually.
3. Millions of people around the world use the Internet to search for and retrieve information on all sorts of topics in a wide variety of areas including the arts, business, government, humanities, news, politics and recreation. People communicate through electronic mail (e-mail), discussion groups, chat channels and other means of informational exchange. They share information and make commercial and business transactions. All this activity is possible because tens of thousands of networks are connected to the Internet and exchange information in the; same basic ways.

4. The World Wide Web (WWW) is a part of the Internet. But it's not a collection of networks. Rather, it is information that is connected or linked together like a web. You access this information through one interface, or tool called a Web browser. The number of resources and services that are part of the World Wide Web is growing
extremely fast. In 1996 there were more than 20 million users of the WWW, and more than half the information that is transferred across the Internet is accessed through the WWW. By using a computer terminal (hardware) connected to a network that is a part of the Internet, and by using a program (software) to browse or retrieve information that is a part of the World Wide Web, the people connected to the Internet and World Wide Web through the local providers have access to a variety of information. Each browser provides a graphical interface. You move from place to place, from site to site on the Web by using a mouse to click on a portion of text, icon or region of a map. These items are called hyperlinks or links. Each link you select represents a document, an image, a video clip or an audio file somewhere on the Internet. The user doesn't need to know where it is, the browser follows the link.
5.All sorts of things are available on the WWW. One can use Internet for recreational purposes. Many TV and radio stations broadcast live on the WWW. Essentially, if something can be put into digital format and stored in a computer, then it's available on the WWW. You can even visit museums, gardens, cities throughout the world, learn foreign languages and meet new friends. And of course you can play computer games through WWW, competing with partners from other countries and continents. Just a little bit of exploring the World Wide Web will show you what a much of use and fun it is.
