1.2 Data Storage
An SSD drive uses direct access to data/a file
There would be no deterioration in read times as there is no physical read-head move
Binary digit, single 1 or 0
Data is not stored on the medium in one continuous block, files are fragmented(split up and stored on different parts of the disk).
This process is when file fragments are reorganised to make accessing them more efficient.
This also speeds up how fast the computer runs.
A generation file backup system
This involves storage of three of the most recent versions of the master file
Useful if one version is corrupted: the previous version(s) is still available
Data should be stored off site in case of disaster
Only backs up data that has changed and writes over older back ups
Useful as it saves storage space and is faster than full backup
Only allows the user to restore the most recent backup
