                                            1. Reducing the size of the file by performing an algorithm on the original data
                                              1. Lossless-The original file can be re-created as no data is lost
                                              2. Defragmentation Software
                                                1. When a hard disk drive is new, files get added onto the disk in order. Very much like starting with a blank piece of paper and adding to it
                                                  1. As files are deleted this leaves gaps
                                                    1. When new files are saved the files fill the gaps and become fragmented
                                                      1. Defragmentation software groups fragmented files back together
                                                      2. Encryption Software
                                                        1. Encryption emans to scramble data in a way that it is unreadable to anybody who doesn't have a key to be able to unscramble this
                                                          1. Data is encrypted using a key and then decrypted using a key
                                                            1. Data is encrypted so that it is unreadable if anyone is to intercept it
                                                            2. Backups
                                                              1. Completed to ensure there is way of restoring files/data/programs in case of computer failure
                                                                1. Copies of data and/or software are taken regularly and usually stored in a difrent location
                                                                  1. Ensures that if computers are stolen or damaged in for e.g. a fire or a natural disaster that data can be restored and a company do not lose much money
                                                                  2. Backup Types
