A horrible, crappy kludge used on the x86 in 16-bit realmode (and v86 as well) to get more than 64k of addressable memory with a 16-bit addressing mode. It basically gives the programmer 20-bit addressing in 16-byte chunks, sorta (each&chunk, alternately called a "page" or "paragraph," is actually 64k, but they overlap so that any one paragraph can be represented in 4096 different segments). (continued in x86 DS:2)
