LESSON 4

                                        THE NETWORK

       The network is a two or more computers connected together. This is done for two reasons:
       – To allow human beings to communicate;
       – To share resources.
       A local Area Network (LAN) is a network in which the computers are connected directly.
Usually by some type of cable. When LANs are connected together it is called then a Wide Area
Network (WAN). Most WANs are connected via telephone lines, although the bottleneck in es-
tablishing Internet service within developing countries is usually due to the lack of a reliable tel-
ephone system.
       Examples of LANs and WANs are the following. Imagine yourself sitting in a room full of
computers in the Computing Center of your University. Your computer is connected in a LAN
to all other computers in the room and to the computers within private offices throughout the
building. Or, for instance, each department of your University has its own network of comput-
ers, as does the other department (the Sociology/Psychology department, the Foreign Languag-
es department, The Math department, The Computer Science department, The Philosophy de-
partment, etc.) Each of these LANs is connected to a high-speed link, called a backbone, to
form a campus-wide WAN.
