摘要

Removable data medium, such as a CD-ROM comprises a computer operating system, one or more applications for processing information stored on it and on a server via a network connection. The operating system and application operate independently of the host system and do not need to make any changes to the host system setup, BIOS, or otherwise. Similarly no change is made to the software of information held on it.
