Imagine you're studying for your GCSEs. You use a whiteboard for working out problems - it's quick to write on and erase, perfect for temporary work. But when you turn off the light and leave, everything disappears! You also have a printed textbook - you can't write in it (well, you shouldn't!), but all the information stays there permanently, even when you close it. This is exactly how RAM (the whiteboard - fast but temporary) and ROM (the textbook - permanent but unchangeable) work in your computer!
This introduction covers The Whiteboard vs. The Textbook within RAM and ROM for GCSE Computer Science. Revise RAM and ROM in 3.4 Computer Systems for GCSE Computer Science with 16 exam-style questions and 16 flashcards. This topic appears less often, but it can still be a useful differentiator on mixed-topic papers. It is section 1 of 11 in this topic. Use this introduction to connect the idea to the wider topic before moving on to questions and flashcards.
