Portable (portable application) is a program variant that does not require installation and can work from a handheld device, for example, a flash drive.

 

In Windows operating system, it is normal to make special program installers that deal with the initial installation and configuration of software. These programs extract files, write them to the right folders on a hard drive, save parameters and settings to the Register, etc.

 

On one side it's convenient as a user don't have to deal with installation and configuration, but on the other side a person who uses a program on the other computer faces two problems:

 

1.when installing the program you need the rights that you may not have;

2.installing the program on another program can be not secure. For example, the program can contain confidential information.

 

Portable programs do not have these flaws because they do not require installation on a computer and do not save any information on a hard drive. You can write them on your flash drive and use them everywhere not worrying about the lack of rights for installation and confidentiality of private data.
