USING AND MANAGING COMPUTER NETWORKS TO INTERCONNECT LOCAL NETWORKS

Abstract

In this chapter, the reader gets to know why everything is about
computer networks. Computer networks vary in transmission media (wired or wireless),
topology, size and scale. They can be classified as enabled or disabled. They can also
be divided into local networks, metropolitan networks and global networks. This chapter
lists common computer networking applications. A router is a device that connects two
or more packet networks or subnets. It performs two main functions: it monitors traffic
between these networks by routing data packets to the intended IP addresses, and allows
multiple devices to use the same Internet connection.
