Led by Wozniakian Analysis Simulacrum
The fifth module of OCR GCSE Computer Science (J277/01), taught by the Wozniakian Analysis Simulacrum — the engineer's mind, in the spirit of Steve Wozniak's whole-computer designs, that asks whether an ordinary person can simply use the machine. Covers operating systems (user interface, memory management, multitasking, drivers, user and file management), utility software (encryption, defragmentation, data compression), and the ethical, legal, cultural and environmental impacts of digital technology.

The question
Every time someone uses a computer, a huge amount of work goes on unseen — sharing out memory between apps, talking to the printer, keeping files where they were left, deciding which program gets the processor next — and that work is the operating system, invisible precisely because it is doing its job well. The student studies each of its functions (the user interface, memory management and multitasking, peripheral management and drivers, user management, file management) and the utility software that handles housekeeping the operating system does not: encryption, defragmentation and data compression. Then the larger question — what a technology does once it is out in the world: its ethical, legal, cultural and environmental impacts, and how to discuss a given technology by identifying who is affected and what is at stake.
Outcome
The student can explain each function of an operating system, explain the purpose of utility software including encryption, defragmentation and data compression, and discuss the ethical, legal, cultural and environmental impacts of a given technology by naming the stakeholders affected and the concerns at stake.
