- 1What is Optical Memory?Optical storage is the storage of data on an optically readable medium. Data is recorded by making marks in a pattern that can be read back with the aid of light, usually a beam of laser light precisely focused on a spinning optical disc.
- 2What is magnetic memory?Magnetic storage or magnetic recording is the storage of data on a magnetised medium. Magnetic storage uses different patterns of magnetisation in a magnetisable material to store data and is a form of non-volatile memory. The information is accessed using one or more read/write heads.
- 3What is Reliability?Reliability is an attribute of any computer-related component (software, or hardware, or a network, for example) that consistently performs according to its specifications.

- 4What is Durability?Durability is how long a hard drive can survive and how much damage it can take.
- 5What is Open Source code.Open source is where anyone can input to the code, making it much stronger as more people can work on it.
