System Software: UtilitiesA utility program performs tasks related to the maintaining of your computer's health - hardware and data. Some are included with the operating system. But someone always thinks they have a better version for you to buy. And they are frequently right!
In the high days of DOS it didn't take much to improve on the text-only type-it-all-yourself methods that DOS provided. Many programs were written to help the user find files, create and organize directories, copy, move, and rename files. Some even used the mouse to point and click to accomplish these tasks. You don't appreciate the vastness of the improvement until you've tried to do these things by typing the commands. The newer graphical interfaces that come with current operating systems have reduced the need for alternate file management programs.
Defragmenting means putting files on the disk so that the whole file is in sequence. This reduces the time to access the file. Some disk management programs even let you specify that certain files that are accessed often, like the operating system itself and frequently used programs, are at the front of the disk. Anything that speeds things up will have customers.
Your backup files can be on a hard disk, flash disk, CD or DVD disc, or stored in the "cloud" (a remote server that you access over the Internet). Some online services will automatically synchronize files and even allow access to the online copy from a different computer.
