A particular focus is made on PCs and successful learners will be able to explain the use of the more commonly available hardware components that they contain.
At the end of the unit, successful learners will be able to make informed choices when selecting a personal computer (PC) for a particular set of tasks or for a particular user. To do this, learners will understand about the different parts of a computer system, how they connect together and how the capacity and performance of these devices are recognised. Different speeds for transmitting data will be considered.
Learners will also look at different types of software — applications that allow people to perform the tasks that they need to do and systems software (such as the operating system and utility programs) that manage computer resources and allow applications to run efficiently.
Much of the unit involves building up an understanding of the hardware and software but there is also a practical element and learners will need to demonstrate that they can safely connect hardware devices and configure software for a defined user.
Individuals have different needs and the ability of software to be configured to specifically suit those needs is necessary in order for individuals to make the best use of the technology.
With the increased use of computers for holding personal information and the ability to share that information around the world, security considerations are very important. Learners will study how security threats can be reduced and what legislation there is to protect information.
Health and safety issues are always important when setting up and using electronic equipment. Learners will understand the different hazards involved in setting up machines such as the dangers of using electricity and manual handling of heavy devices such as monitors. In normal use of computers there are other potential hazards such as RSI (repetitive strain injury) and eyestrain.
