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:
“Neither dead nor alive, the hostage is suspended by an incalculable outcome. It is not his destiny that awaits for him, nor his own death, but anonymous chance, which can only seem to him something absolutely arbitrary.... He is in a state of radical emergency, of virtual extermination.”
—Jean Baudrillard (b. 1929)
“I believe the alphabet is no longer considered an essential piece of equipment for traveling through life. In my day it was the keystone to knowledge. You learned the alphabet as you learned to count to ten, as you learned “Now I lay me” and the Lord’s Prayer and your father’s and mother’s name and address and telephone number, all in case you were lost.”
—Eudora Welty (b. 1909)
“But alas! I never could keep a promise. I do not blame myself for this weakness, because the fault must lie in my physical organization. It is likely that such a very liberal amount of space was given to the organ which enables me to make promises, that the organ which should enable me to keep them was crowded out. But I grieve not. I like no half-way things. I had rather have one faculty nobly developed than two faculties of mere ordinary capacity.”
—Mark Twain [Samuel Langhorne Clemens] (1835–1910)
