Types Of Peripheral Devices - Storage
Gbogbo ọrọ náà
Every photograph, document, song and application on your devices needs somewhere to live when the power goes off. Storage technology determines how much you can keep, how quickly you can reach it and whether it will still be there in ten years. Choosing the right storage for a task is one of the most practical decisions in ICT.
In this lesson you will distinguish between storage devices and the media they read, compare hard disk drives with solid-state and optical alternatives, and master the binary-based units that describe capacity. You will also practise the kind of conversion calculations that Edexcel regularly tests in Paper 1.
