Networks - Revision

This unit only appears on Paper 2.

This means that questions on it will be knowledge based. You need to learn definitions and the key knowledge elements of the syllabus and will have to write about them.

There may be longer questions on any part of this unit as well as hacking and cracking. The whole unit crosses over in to Unit 8 (ethics) territory.
