Welcome to Computer Basics. In this module we'll explain what a computer is and how it works.

Desktop computers have been popular with consumers since the late 1980s. These days, computers come in all shapes and sizes – from traditional desktops used for work in a home office to ultra-compact smartphones that fit in your back pocket. Regardless of their size, all computers have the same basic components and work in a similar fashion.

At the end of this training you will be able to:
  • Describe the technical specifications of a computer that are relevant to consumers.
  • Explain how the CPU and memory impact how fast a computer runs.
  • Help customers determine the features they need in a new computer.
