Answer:

The Internet and its Services: A Brief Review

The Basic Structure of the Internet

The Internet is a heterogeneous worldwide network consisting of a large number of host computers and local area networks. The Internet uses the TCP/IP suite of protocols. This allows the integration of a large number of different computers into one single network with highly efficient communication between them. This way, the user can access information on all kinds of host computers from a desktop PC, Macintosh, or whatever he/she has available.

Major Internet Services

Internet services can be divided into two groups (Maier, Wildberger, 1993a): communication services and information services. In the first group the Internet mediates in the communication between two or more individuals. In the second group the user turns to the Internet-service in search for some particular information. Communication services can roughly be compared tvices can roughly be compared to a telephone call, information services to a dictionary (of course, the dividing line between the two types of services is fuzzy; for a discussion of the relationship between traditional and electronic forms of communication see Maier, Wildberger, 1993b).

The most important communication services on the Internet are electronic mail (and some derived services) and netnews. Major information services are terminal emulation and file transfer, Gopher, WAIS, and World Wide Web. We will discuss them very briefly below (for a more detailed discussion see e.g., Maier, Wildberger, 1993a; Krol, 1992).

Communication Services

Electronic mail (e-mail) is the most popular and widely used network service. It can be viewed as the electronic equivalent to a regular mail letter. When one user wants to send a message to another Internet user, he/she types the message into a special computer program, adds the e-mail address of the recipient, and sends the message off through the network. Typically the message reaches its destination almost immediately, even when it is on another continent. Practically all gateways between the Internet and other computer networks can handle e-mail messages. Therefore, many more people can be reached by e-mail than are connected to the Internet via TCP/IP.

The major advantage of e-mail over regular mail is that an e- mail message comes in electronic form. Therefore, it cectronic form. Therefore, it can easily be handled and interpreted by a computer program. This feature is use by electronic discussion lists. They operate a database of subscribers and each incoming e-mail message is automatically distributed to each subscriber. LISTSERV, the most popular program for managing discussion lists, also handles subscription via mail messages, archives incoming messages, and allows users to retrieve these and other archived files (for a discussion of LISTSERV see Maier, Wildberger, 1993a,b, Kovacs et al., 1991).
