No matter what you are working on, whether at home, school or in an office, you will want to save your data for use at a later date. Whilst you have the document, spreadsheet, database open, the work is mostly residing in your computer's Random Access Memory (RAM).  However, as you know, this is volatile, so when you turn your computer off, all of your hard work will simply disappear unless you save it to somewhere more permanent.

There are many different types of storage devices, some you are familiar with, some you may not have come across before.

In the exam, you are likely to be presented with a situation, given some details and then asked to recommend a suitable storage device, giving justification for your answer.  You may alternatively be provided with a storage device and asked to suggest a situation where it could be used.
