Visualise an office with a filing cabinet and your desk. Stuff (documents in our theoretical example) could be stored away in the filing cabinet for use as and when needed. It would make sense to keep copies of documents you use frequently and are constantly referring to in a little tray on your desk wouldn't it? To save you from walking over to the cabinet and searching through all the time? The tray on your desk is a 'cache'. A computer running a program will do this. Permanently storing away data on its fixed disc drives and opening them as and when required. And by 'caching' frequently used data so it can get to it quickly. It can't cache everything, just like you can't get a cabinet full of documents in a little tray. And a massive tray would defeat the object, you'll spend ages searching through it the pile of paper! So the cache in a computer is likewise kept small (fast and easy to access). So caching makes a computer run faster, more efficiently from the users point of view. Which is a good thing. Is that any help?
