Your journey to the ICDL starts with the first module, "Concepts of Information Technology." Just as learning to drive an automobile starts with a basic understanding of what a car is, where you can drive it, and why you'd want to do so, learning to drive your computer requires you to understand some basic concepts. This module covers eight general areas:
IT concepts
Computer hardware
Types of software
The use of networks
IT in everyday life
Health, safety, and environmental issues
Computer security
Legal aspects of IT
You'll learn about each of these areas in this chapter. By the end of the chapter, you'll be ready to go out and take the test for the first module!
