translation (n)~ The process of moving an object in the 2D x-y coordinate system. translation lookaside buffer (n)~ A table used in a virtual memory system that lists the physical address page number associated with each virtual address page number.

The virtual address is presented simultaneously to the TLB and to the cache so that cache access and virtual-to-physical address translation can occur simultaneously.
