TLB - convert from virtual memory addresses to physical memory 
addresses. It's basically a cache of the page mappings. (Let's face it, 
accessing RAM for every memory access to figure out where in physical 
memory the requested virtual address is would be *really* slow...)

I only know this because I read the Intel reference manuals. For no 
reason other than curiosity.
