virtual address
logical address

   1.  A memory location accessed by an
   application program in a system with virtual memory such
   that intervening hardware and/or software maps the virtual
   address to real (physical) memory.  During the course of
   execution of an application, the same virtual address may be
   mapped to many different physical addresses as data and
   programs are paged out and paged in to other locations.

   2. In IBM's VM operating system, Virtual Device
   Location.
