Here are some tips to make this a good year.
Remember, good learning begins in the classroom!

Keep to your timetable.
Study time is a priority – it is one of the most important things in your life at school.
Find a quiet place to study. (Try a quiet classroom at school or the local library if
possible.)
Choose study partners who are serious about doing well to work with you.

Overview
It is important for you to revise the hardware and software concepts that you learnt in Grades
10 and 11. In this chapter, you will learn about: general concepts of computing; hardware
input and output devices; hardware storage devices and processing procedures; software and
software management; and computer management.
Unit 1 (General concepts) reinforces the information processing cycle, types of computers
and their typical features. Different computer categories and the reasons for using computers
as well as the convergence of technology is investigated.
Unit 2 (Hardware) is about make buying decisions and how to fix ordinary computer-related
problems. You will investigate and reinforce new technologies and social implications.
Unit 3 (Software) covers software that enhances accessibility, efficiency and productivity, and
the use of common applications software. You are required to interpret system requirements
and choose software for a specific situation. We also cover the risks of using flawed software
and user-centred design.
Unit 4 (System software and computer management) covers the role of the operating system
within a computer and investigates the factors that influence the speed of a computer.
