Partition tables

Partitioning is the address range where the volume with a file system can sit. You create a partition, then you format it to create a volume with a file system. So, partition and volume are not interchangable terms. Usually, a volume occupies the whole partition, but that’s not always the case. Sometimes, some little address sapce might be left out of the volume, so that this volume would not occupy the whole partition.

There are currently three main partition tables: MBR, GPT and APM (Apple’s).
