In computing, virtual address space (abbreviated VAS) is a memory mapping mechanism available in modern operating systems such as OpenVMS, UNIX, Linux, and Windows NT. This is beneficial for different purposes, one is security through process isolation. An address generated by the process is called logical address (virtual address) and it is mapped to the virtual address space.

Famous quotes containing the words virtual, address and/or space:
“Tragedy dramatizes human life as potentiality and fulfillment. Its virtual future, or Destiny, is therefore quite different from that created in comedy. Comic Destiny is Fortune—what the world will bring, and the man will take or miss, encounter or escape; tragic Destiny is what the man brings, and the world will demand of him. That is his Fate.”
—Susanne K. Langer (1895–1985)
“Take a red book called TELEPHONE,
size eight by four. There it sits.
My red book, name, address and number.
These are all people that I somehow own.
Yet some of these names are counterfeit.”
—Anne Sexton (1928–1974)
“Not so many years ago there there was no simpler or more intelligible notion than that of going on a journey. Travel—movement through space—provided the universal metaphor for change.... One of the subtle confusions—perhaps one of the secret terrors—of modern life is that we have lost this refuge. No longer do we move through space as we once did.”
—Daniel J. Boorstin (b. 1914)
