Virtual memory gives the illusion of a bigger memory. Each programs use the same virtual addresses.
Physical memory acts as a cache for virtual memory. A page table can be used to translate virtual to physical address.
Most accesses hits physical memory, but some doesn't.
A translation lookaside buffer (TLB) is a small cache of recent translations that reduces memory accesses. Page tables are high temporal locality so fully associative.
