The course lays out the general structure of computers, the roles of hardware and software and the technology that allows mass data storage. We discuss operating systems, their various types and the different ways you can maintain your computer.

Computer and cyber security have become some of the most in-demand skills for tech professionals. Our final section provides a general overview of the many ways in which a virus can corrupt your computer and the various cyber-attacks that a hacker can launch to compromise a device. We explain how to keep your data and equipment safe from such attacks and show you how to apply the ‘confidentiality, integrity and availability’ model (CIA triad) to formulate an effective cyber security policy. This basic IT course is suitable for anyone who wants to understand the underlying technologies that drive computers. It also provides the practical skills required to turn this understanding into a useful professional skill. Sign up to learn how to use computers with confidence.
