According to this -

Wired memory is memory in use that absolutely has to stay where it is, ie., the system cannot be allowed to dump the memory out onto hard disk, so that some other program can use it.
Active is data in memory in use by a program, but could be swapped out if necessary.
Inactive is memory that has data in it, but it's not in use by a program, ie., the last program to use it didn't bother cleaning up after itself.
Free is probably memory that has no data in it at all, I would guess.
