What is meant by Translation Lookaside Buffer ?

A translation lookaside buffer (TLB) is a memory cache that stores recent translations of virtual memory to physical addresses for faster retrieval. When a virtual memory address is referenced by a program, the search starts in the CPU. ... As virtual memory addresses are translated, values referenced are added to TLB.
