Data Storage
Random access memory and read-only memory were explained in detail in the previous topic. We learnt how CPU access RAM for programs and data that are currently in use. The contents of RAM are lost when power is switched off. ROM is used for storing a pre-programmed set of instructions such as boot process. The contents of ROM remained intact even when power is switched off. The user now needs a storage device to store media and other files that require large space. This problem is solved by storage devices that work based on magnetic, optical and solid-state principles. In this article, these storage devices are explained in detail.
This GCSE Computer Science module introduces data storage to your students, explaining:
- What are hard disk drives
- How Solid-state drives work
- Optical Storage Systems
- How to the calculate required capacity
- Choosing storage device
- Different types of memory access
