an integral part of a virtual memory system in an operating system, part of which is to translate between virtual addresses, which assumes much larger memory than is actually present, and physical addresses which matches a computer's main memory (ie
a table, one entry for each possible (high bits of) a virtual address, where the entry tells which physical page (block number in the cache) (or "none -- miss") is caching that address
An area of main memory containing sets of virtual addresses with their corresponding physical addresses and protection data.
data structure used by the MMU to translate virtual memory addresses to physical memory addresses.
An array that contains an entry for each current virtual-to-physical address translation.
A page table is the data structure used by a virtual memory system in a computer operating system to store the mapping between virtual addresses and physical addresses. Virtual addresses are those unique to the accessing process. Physical addresses are those unique to the CPU, i.e., RAM.
