Although it is theoretically possible to use a full disk to house a Linux system (when creating a btrfs RAID for example), this is almost never done in practice. Instead, full disk block devices are split up in smaller, more manageable block devices. On systems, these are called partitions. There are currently two standard partitioning technologies in use: MBR and GPT.
