How to create a partition for your computer hard drive.

Why is it important to partition the drive of your system? When installing applications on your system, it is likely that at some point one of the apps may get corrupted.  This results from updates from the software or virus obtained from external storage devices like flash disks plugged in the system. Partioning your hard drive is simply dividing it into different sections which can be managed separately. If you have one drive on your system, you can create two partions and use one for the main Operating system and the other part for your backup files.
