Hardware And Software
Overview
Two computers can be identical in every physical respect and be completely different machines to use. One runs a till in a shop, one edits video, and the metal, silicon and plastic inside them are the same. That is the most important fact in this whole specification, and it has a name: the division between hardware and software. A computer is not one thing, it is two things that need each other, and neither is any use on its own.
This lesson defines both terms precisely enough to survive an exam question, works through the cases people get wrong, and then does the harder and more interesting part: explaining the relationship between the two. You will finish able to classify anything you are shown, to justify the classification rather than assert it, and to explain why the separation is what makes a computer a general purpose machine rather than a very expensive single purpose one.
Objectives
- Define the terms hardware and software and understand the relationship between them.
