Computer Hardware

1. Relatively cheap per unit of storage. Fast access and retrieval times compared to other storage devices.

   • Advantages

2. Disadvantages

   • Can be easily damaged, will slow down and eventually break over time. Slower access than Solid State Drives

3. Principally used for backup of important files from the hard disk and for the long term storage and archiving of data.

   • Magnetic

4. Solid state devices use non-volatile random access memory (RAM) to store data indefinitely.

5. Optical devices use a laser to scan the surface of a spinning disc made from metal and plastic.

   • Optical

6. Random Access Memory (RAM) is a fast temporary type of memory in which programs, applications and data are stored.
