Installation (or setup) of a computer program (including device drivers and plugins), is the act of making the program ready for execution. Because the process varies for each program and each computer, programs (including operating systems) often come with an installer, a specialized program responsible for doing whatever is needed for their installation. Installation may be part of a larger software deployment process.
Common desktop operating systems include Windows, OS X, and Linux. While each OS is different, most provide a graphical user interface, or GUI, that includes a desktop and the ability to manage files and folders.

The simplest definition of a computer backup is an exact copy. In the case of computer files, we are referring to copies of the original files that you have on your laptop, desktop, or external drive. Creating a backup of original content means having that data saved in two places, but it’s also important to make sure that those two places aren’t on the same type of device. For example, if you have 3 copies of a working document on your computer, if your computer crashes, you will still lose all three. This makes the backup method and medium, an important thing to consider for your backup strategy!
