Learning objective
Explain computers, hardware, and software, reproduce the worked example and justify a decision in the case study.
Before you begin
Programming and algorithms
Understand
Hardware executes and stores; software gives instructions; the operating system coordinates resources.
Worked example
RAM holds working data; storage keeps it longer.
Analysis and common mistakes
The processor executes instructions, RAM holds active work, and storage retains files after shutdown. More storage does not automatically fix insufficient RAM.
Case study — reasoning
A device slows with many tabs despite free disk space. Examine memory use and applications before buying storage; the symptom can have multiple causes.
Knowledge check
Summary
Hardware executes and stores; software gives instructions; the operating system coordinates resources.
