Partitioning is a means to divide a single hard drive into many logical drives. A partition is a contiguous set of blocks on a drive that are treated as an independent disk. A partition table is an index that relates sections of the hard drive to partitions.

   /dev/hda1      The 1st primary partition
   /dev/hda2      The 2nd primary partition
   /dev/hda3      The 3rd primary partition
   /dev/hda4      An extended partition
   /dev/hda5      The 1st logical partition
