Definition: "sysv" - sysv means "server," an abbreviation for "software server." It typically refers to a system or program where applications are served from other systems (servers) rather than being directly executed by the user's local machine, as in Unix/Linux/OS X systems. This is done through the use of the 'sysvserve' command or via a virtual server program called 'sysv.' The word "system" and "server" are also used interchangeably in this context.
