LPIC 101.1 (75 Cards)

Aside from logical, primary, and extended partitions, there is another class of partitions that should be recognized. What are they, and how are they classified in the x86 architecture?

The x86 partition table supports partition type codes, which are two-digit hexadecimal numbers that are assigned to specific functions.

Examples:
0x06 is reserved for a certain type of File Allocation Table (FAT) partition.
0x82 denotes a Linux swap partition.
0x83 denotes a Linux file-system partition.

Operating Systems like Windows and DOS rely more on type code partitions than Linux, but there are exceptions. What are they?

During installation, most Linux distributions pay attention to the partition type codes to help them guess how the system is configured. Installers and Linux disk utilities also create partitions with appropriate type codes set.
Linux relies on the extended partition type codes (0x05 and 0x0f) to identify extended partitions. You can try to act directly on the extended partition using various utilities, but for the most part doing so would be a mistake.
