FreeBSD has a much longer history than Linux, because of this
it sometimes reports in what appear to be odd ways. There is a
section somewhere in the handbook that goes over this but here is
the short of it.
Partitions on a disk are named using a letter from "a" to "g". By
convention partition c is the whole disk. Size and offset are
quoted in blocks of 512 bytes. Fstype is looked up in a table that
is defined in /usr/include/sys/disklabel.h. The other columns
have to do with file allocation specifics on the disk.
Hope this helps

If it's not in the book, and it was not covered in the lecture,
then we'll cover it on the test.
