TLB (Translation Lookaside Buffer)

A Translation Lookaside Buffer (TLB) is a small, fast memory within a computer's processor that stores recent translations of virtual memory addresses to physical memory addresses. When a program accesses data, the TLB quickly provides the address conversion, reducing the time compared to retrieving this information from the main memory translation tables. Essentially, it acts as a cache for address translations, speeding up data access and improving overall system performance by minimizing delays caused by address translation.
