What Are Portable Apps & Why Use Them?
Portable Application: “a software program that does not require any kind of formal installation onto a computer’s permanent storage device to be executed, and can be stored on a removable storage device such as a CD-ROM, USB flash drive, flash card, or even a floppy disk, enabling it to be used on multiple computers.” – Wikipedia (http://en.wikipedia.org/wiki/Portable_application ) Use portable applications when you want access to software that might be unavailable on a computer that you happen to be using.
