Aunt Wiki says that "a portable application, or portable app for short, is 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. This does not mean that it can be taken and used on a different operating system, processing platform, or another computer with completely different hardware (i.e., those that are not compatible with the software as stated by its requirements), so it is not to be confused with the concept of software portability, which is the ability for software to be run or compiled with little modification on diverse computing platforms. Ideally it can be configured to read its configuration files from the same storage location as the software program files."
Today, along with the willingness of simplicity, rapid advance of technology development encourages people to create as simple as possible technology supporting their daily needs. In the case of software development, people has began to prefer light applications that can be used instantly without necessities to install and configure it before hand as the conventional applications require. Time, mobility, and simplicity boost the need of such kinds software which can be used fast, no installation, and possible to be brought along wherever needed in a tiny storage.
Quoted from PortableApps.com, imagine such conditions when you can:
- Carry your web browser with all your favorite bookmarks
- Carry your calendar with all your appointments
- Carry your email client with all your contacts and settings
- Carry your instant messenger and your buddy list
- Carry your whole office suite along with your documents and presentations
- Carry your antivirus program and other computer utilities
- Carry all your important passwords and account information securely
- Consider the Convenience...
- Have your favorite websites handy to recommend to a friend or colleague
- Have your presentation AND the required software ready to go for that big meeting
- Have your password with you if you want to bank online while traveling
- Have utilities handy when visiting family or friends that are having PC problems
As a result, it has bloomed a trend of three NOs in software choice:
- No Special Hardware - Use any USB flash drive, portable hard drive, iPod/MP3 player, etc
- No Additional Software - Just download the portable app, extract it and go
- No Kidding - It's that easy
To underscore what I mean with this posting, just simply think about a computer program that you can carry around with you on a portable device and use on any computer. When your USB flash drive, portable hard drive, iPod or other portable device is plugged in, you have access to your software and personal data just as you would on your own PC. And when you unplug the device, none of your
personal data is left behind.
