Basic Concepts of Network

[Symon]

Networks are everywhere—or so it seems. You can hardly do anything with data that does not involve a network. Like the human networks that we are all part of, computer networks let us share information and resources. In business, the reliance on networks is even more pervasive than in homes or schools. Networks help individuals and businesses alike save money, but they also help create income. Without a doubt, networking within the home will catch on over the next few years as it has in business. Soon, nearly all individuals in even moderately developed nations will have networked components throughout their homes. Those that don’t will be netologically disadvantaged because they will not be able to learn or to function at the same level as those who are networked. In this chapter, you’ll begin by relating networks to situations and concepts you already know. Once you have a basic understanding of what networks are and what they can do, it helps if you can actually begin working with them. In fact, it is so helpful to learn the ropes of networking through hands-on guided practice that that’s what is planned for you here. You will play the role of an employee in a fictional company, and you’ll have to learn on the job. The more you become the person, the more you will learn about the need for and operation of computer networks.
