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!
