WebWhat is the translation lookaside buffer (TLB)? The cache used to store the page table entries is commonly called translation lookaside buffer. TLB is just a special kind of cache used to maintain the records of recently used transactions. TLB contains the page table entries that have been most recently used by the operating system and CPU.
