IGCSE Information and Communication Technology/1. Types and components of computer systems

The written theory exam is 2 hours long and covers a wide range of topics. Questions range from simple true/false ones, to ones requiring long, extended answers.

Like any other IGCSE subject, ICT theory requires you to understand and learn the facts.

There is no shortcut... you will have to REVISE!

But, hopefully, these notes will help you to gain the understanding required.
