The language used for data transfer on the Internet is known as (1) PPP. This is like the Internet operating system. The first program you need is a (2) Telnet. This piece of software allows the (1) PPP system to work with your modem; it dials up your (3) ISP, transmits your password and log-in name and allows Internet programs to operate.
(4) e-mail is your personal connection to the Internet. It allows you to exchange messages with people all over the world. It can include text, pictures, and even audio and animation. When you set up an account with a(n) (3) ISP you are given a unique address and anyone can send you a message. The mail you receive is stored on the server of your (3) ISP until you next connect and download it to your hard disk.
(5)IRC is a system for real-time (usually typed) conversation. It is easy to use. To start a chat session you run a(n) (5) … program, which connects you to a(n) (5) … server – a computer dedicated to (5) …. Then you join a channel, which connects you to a single chat area. Next you type a message and the other participants can see it.
Internet telephone and video chatting are based on (5) IRC protocols. (6) videoconferencing programs enable users to talk to and see each other, and collaborate. They are used in (7) Intranets — company networks that use Internet software but make their Web site accessible only to employees and authorized users.
With (8) TCP/IP software you can copy programs, games, images and sounds from the hard disk of a remote computer to your hard disk. A(n) (9) FTP program is used to log directly into remote computer systems. This enables you to run programs kept on them and edit files directly.
(10) newsgroups are the public discussion areas which make up a system called ‘Usenet’. The contents of the (10) newsgroups are contributed by people who send articles (messages) or respond to articles. They are classified into categories: comp (computers), misc (miscellaneous), news, rec (recreation), soc (society), sci (science), talk and alt (alternative).
