The Internet 1:
email and newsgroups
When different networks are connected together, the combined network is called an internetwork or internet. The connection of networks throughout the world forms what is known as the Internet. Networks all over the world are connected to the Internet using electronic devices known as routers. The routers decide which route on the Internet a particular signal should take to get to its destination. Users often pay a monthly fee to a type of company known as an Internet service provider (ISP), to provide them with an Internet connection. A variety of services such as email and file transfer are made available to users on the Internet. These services are controlled using a system of server computers at various locations throughout the world.
Electronic mail, which has come to be known as email, is one of the most popular services on the Internet. Email allows users to send electronic messages to storage areas known as mailboxes on server computers where they can be read by other users. Each user has their own email address which determines where their email messages are stored. Every email address has two main parts separated by an at symbol, i.e. username@ domain name. The domain name may be subdivided using dots. A typical email address might have the following components:
Username @ server. type of. country
or identifier name organization
Standard codes are used for the types of organization, although they may vary slightly from country to country. Not all email addresses use all the possible parts of the domain name. An email message has two main parts known as the header and the body of the message. The body contains the message itself, whilst the header reveals the identity of the recipient and of the sender, the date it was sent, and the subject title of the message. The most basic type of email consists of plain text to which other types of computer files, such as formatted text, spreadsheets, sound files, or video files can be attached. These email attachments can then be opened and read using an appropriate program on the recipient’s computer.
Groups of users that share a special interest can subscribe to free newsgroups on the Internet. Subscribers can send plain text messages to a common area on a server computer where all the newsgroup members can read them. In this way, conversations about the special interest can take place between all the members of the group. The name of the newsgroup is made up of different parts separated by dots and indicates the specialist area the subscribers are interested in. For example, newsgroup names that begin with alt indicate that they deal with alternative types of subjects, e.g. alt.tasteless-jokes. Newsgroup names beginning with rec deal with recreational subjects, e.g. rec.chess. When you are replaying to a message, it is common for the email program to include the original message with each line marked with a chevron (>), and if you are replaying to a reply, each line of the original text is marked with double chevrons (>>). In this way the correspondents can keep track of the conversation.
