What is Internal Storage?
This is HDDs and SSDs. These are non-volatile storage.
What is RAM?
It is storage but it has some differences like speed difference and being volatile.
What is Volatile Storage?
It is storage that loses the data stored if it has no power.
What is Non-Volatile Storage?
It is storage that is NOT reliant on power to maintain itself. This means all data is secure.
What is Data Redundancy?
This is just a term for keeping data safe.
What is RAID 0?
It is a method which splits the data between two stores. This improves speed but not redundancy.
What is RAID 1?
It is a method which makes a duplicate at a separate store. This is not good for speed but really good for redundancy.
What is Raid 10?
It is a combination of RAID 1 and 0. It uses both methods of splitting the data and copying it. This is great for redundancy and speed.
What is RAID 5?
This is a method that uses a parity cell. This cell has the difference between all the other correlating parts. This means if one disk goes the data will not be lost mostly as we can find what is missing.
What is a Disaster Recovery Plan?
It is just what the name says. It is a plan that should be made to ensure data integrity.
