Some quick hints: shared are memory segments that can be shared amongst several processes -- think libc mappings. libc is mapped into nearly every process, but only one copy of libc needs to be physical memory; each process memory map shares the segments. (It isn't limited to read-only memory, either.) Buffers and cache I tend to forget over time. I think the buffers is just the data blocks, and cache is the metadata describing the filesystem. But I'm not sure. :) -- http://www.wirex.com/
