Data Recovery Area (recovery): the partition where the recovery resides
kernel Zone (boot): boot partition, which is the ROM packet boot.img the brush-in partition
System Area: is the system storage partition, that is, the ROM package corresponding system partition, this partition factory settings will be relatively large, but this space is dead, you can not modify, that is, you 400M and 100M ROM package storage space is the same size. Different models of this partition are set differently by the manufacturer.
