The specified term refers to the acquisition of a self-contained software application designed for system maintenance and repair. This software is intended to be executable from a removable storage device, such as a USB drive, without requiring installation on the host computer. An example would be obtaining a version of system utilities packaged for use directly from a thumb drive.
The value of this approach lies in its portability and independence from local system configurations. It is advantageous for troubleshooting and resolving issues on multiple computers without altering their existing software installations. Historically, such tools provided technicians and advanced users with a convenient means to perform diagnostics and repairs across diverse environments.
