Lesson 1: Networks
The ability to expand beyond the limit of a single computer in a single office has expanded the reach of the PC to global proportions. Two technologies have driven this expansion: computer networking and the portable computer. In this tutorial, we first take a look at how the networks that link up computers on a global scale are put together. Then we examine the portable computer, whose introduction has allowed users instantaneous access to the computing and networking power of all the latest computer technology anywhere they go.
A network is defined as two or more computers linked together for the purpose of communicating and sharing information and other resources. Most networks are constructed around a cable connection that links the computers. This connection permits the computers to talk (and listen) through a wire.
After this lesson, you will be able to:
Estimated lesson time: 40 minutes
- Define basic networking concepts and describe how a network functions.
- Configure and change network interface cards.
- Define Internet terms and functions.
