Decoding the Jargon P1 P2 M1 Purpose / Aims (learning outcomes) LO1 P1 P2 M1 Understand the components of computer systems Explain the function of computer hardware components Explain the purpose of operating systems Compare the features and functions of different operating systems Introduction (Scenario) You have been approached by a small business WWEA Media (selling music & film memorabilia) who are in the process of transferring from a paper-based system to a computerised one. The owners are not particularly ICT savvy, but are keen to be involved in all aspects of the introduction of the new system so that they can maximise all of the potential benefits. You have been asked to create an information leaflet (in publisher) that will be made available for ABEC Media staff who may have little or no understanding of how a computer s hardware components work. Additionally, your leaflet will also provide an explanation of the purpose, features and functions of different operating systems software too.
