Lesson 18
1. Read and translate the text into Ukrainian:
Computer Networks
The communication of data over telephone lines and by radio is one of the most important and influential uses of computers. Using modems, people can send texts and graphic files, exchange messages, and search databases over worldwide computer networks. As more of the world's information is digitized, more people seek access to the global `digital library'. The combination of computers, modems, databases, and communications lines has become known as the information superhighway.
The World Wide Web consists of tens of millions of documents, databases, bulletin boards, and electronic publications, such as newspapers, books, and magazines. Much of the information has been converted from print into digital form, but even more has been created specifically for the Web.
Every site on the Internet-whether a World Wide Web site or not-has a computer address is known as the site's uniform resource locator (URL). Using software that connects to the Internet-called navigation or browser software-a computer operator can select a URL that contains information the operator wishes to examine. The computer then contacts that address, making the information available to the operator.
Computers can connect to the Internet through local access providers, computer services that operate in most communities. The user pays the provider a monthly fee. To gain access to the Internet, the user contacts the provider via modem. The provider then connects the user to the Internet.
On-line services are commercial computer networks to which subscribers pay monthly or hourly fees. The largest on-line services have millions of subscribers. Most services provide news, bulletin boards, databases, games, software libraries, and other features, often including Internet access.

Lesson 19
The Computer Industry
The manufacture, development, sales, and servicing of computer hardware and software make up one of the largest industries in the world. The United States has the world's largest computer industry, employing more than 2 million people. The United States also have more computers than any other country. Japan ranks second in number of computers.
Manufacturing. From a few dozen companies in the early 1960's, the computer industry has grown to more than 10 000 firms throughout the world. These companies manufacture computers and such peripheral equipment as modems and printers. They also develop and publish software and provide computer supplies, such as magnetic discs. Many companies make computer components, including processors. Others make the boards and cables used to create networks.
In the mid-1990's total annual sales of computer hardware and software in the United States exceeded 200$ billion. The largest computer manufacturer in the United States-and the world-is International Business Machines Corporation (IBM), the Hewlett-Packard Company ranks second. Other leading U.S. computer makers include Digital Equipment Corporation, Dell Computer, Apple Computer Inc., Compaq Computer Corporation, and Sun Microsystems Incorporated.
The largest computer manufacturers outside the United States are Fujitsu and NEC Corporation, both o Japan. The leading computer companies in Europe include Group Bull of France and Siemens AG of Germany. The largest software company in the Unites States and the world is Microsoft Corporation.

Lesson 20
Computer Security
Many people fear that their right to privacy is threatened by the possible misuse or unauthorized disclosure of information in computer databases. Certain databases hold private and personal information, such as medical, banking or tax records. Others contain business plans or inventions that a company wishes to conceal from competitors. Still others store top-secret military information and other kinds of data important to a nation's security. Laws limit the disclosure of information in databases, and operating systems are designed to prevent unauthorized entry into a computer. Many computers require a user to enter a secret password. In addition, some computer systems automatically scramble information so it can be decoded by authorized personnel. But, computer crimes still occur. Industrial spies and thieves often use telephone lines to gain access to computers. Some of these criminals steal or change the information in a computer database. Others steal money by transferring funds electronically. In the late 1980's computer experts became aware of a dangerous type of program called a computer virus. A computer virus s designed to do mischief, sometimes by deleting or changing information and sometimes by simply inserting a message. A virus can enter a computer's operating system via a modem, a floppy disc, or a CD-ROM. A virus can spread through a network. Antivirus programs are available to prevent viruses.
