Faces of the Internet

 

I. Read and translate the text

 

What the Internet is

The Internet is an International computer Network made up (що складається з) of thousands of networks linked together. All these computers communicate with one another; they share data (обмінюватися даними), resources, transfer (передавати) information, etc. To do it they need to use the same language or protocol: TCP/IP (Transmission Control Protocol (протокол управління передачі)/ Internet Protocol (Інтернет - протокол)) and every computer is given an address or IP number. This number is a way to identify (розпізнати) the computer on the Internet.

 

Getting connected (підключення)

To use the Internet you basically need a computer, the right connection software and a modem to connect (підключати) your computer to a telephone line and then access (мати доступ) your ISP (Internet Service Provider).

The modem (modulator-demodulator) converts (перетворювати) the digital signals stored in the computer into analogue signals that can be transmitted over telephone lines. There are two basic types: external (зовнішній) with a cable (кабель) that is plugged (що вмикається) into the computer via (через) a USB port, and internal (внутрішній), an expansion card (плата розширення) inside the computer. A PC card modem is a different, more versatile (універсальний) option for laptops and mobile phones.

At first most computers used a dial-up telephone connection that worked through the standard telephone line. Now a broadband (широкий діапазон) connection, a high data transmission rate (швидкість передачі) Internet connection, has become more popular: either ADSL (Asymmetric Digital Subscriber Line) (асиметрична цифрова абонентська лінія), which allows you to use the same telephone line for voice and fast access to the Internet, or cable, offered by most TV cable providers.

The basic equipment has changed drastically (докорінно) in the last few years. You no longer need a computer to use the Internet. Web TV provides (забезпечувати) email and access (доступ) to the Web via a normal TV set plus a high-speed modem (високошвидкісний модем). More recently, 3Generation, mobile phones and PDAs, personal digital assistants (персональні цифрові секретарі), also allow (дозволяти) you to go online with wireless (безпровідний) connections, without cables.

Telephone lines are not essential (необхідний) either. Satellites orbiting the earth (супутники що обертаються навколо землі) enable your computer to send and receive Internet files. Finally, the power-line (лінія електропередачі) Internet, still under development, provides access via a power plug (штепсельна вилка).

 

Components of the Internet

The Internet consists of many systems that offer (пропонувати) different facilities (можливості) to users.

WWW, the World Wide Web, a collection of files or pages containing links (що містять посилання) to other documents on the Net. It’s by far (безперечно) the most popular system. Most Internet services are now integrated (доступні) on the Web.

Email, or electronic mail, for the exchange of messages and attached files (файли-додатки).

Mailing lists (розсилка) (or listservs) based on programs that send messages on a certain topic to all the computers whose users have subscribed (підписані) to the list.

Chat and instant messaging (миттєвий обмін повідомленнями), for real-time conversations; you type your messages on the keyboard.

Internet telephone, a system that lets people make voice calls via the Internet.

Video conference, a system that allows the transmission of video and audio signals in real time so the participants (учасники) can exchange data, talk and see one another on the screen.

File Transfer Protocol (FTP) (протокол передачі файлів), used to transfer files between computers.

Newsgroups (групи обміну інформацією), where people send, read and respond (відповідати) to public bulletin board (дошка оголошень) messages stored on a central computer.

TELNET, a program that enables a computer to function as a terminal (термінал) working from a remote computer (віддалений комп’ютер) and so use online databases or library (бібліотека) catalogues.
