Whatis meant by translation lookaside buffer?

A translation lookaside buffer (TLB) is a memory stash that decreases the time it takes to access a user memory location. TLB includes the most lately used page table entries.

TLB is used to overcome the issue of sizes at the time of paging. PTE is used for framing the memory ,but it uses two references one for finding  the frame number and the other for the address specified by frame number.
