This component will introduce learners to the Central Processing Unit (CPU), computer memory  and storage, wired and wireless networks, network  topologies, system security and system software.  It is expected that learners will become familiar with  the impact of Computer Science in a global context  through the study of the ethical, legal, Cultural and  environmental concerns associated with Computer Science.

It is expected that learners will draw on this  underpinning content when completing the  Programming Project component (03 or 04).

This Unit is assessed by a 1 hour and 30 minute examination which is worth 40% of your final grade.
