LINUX partition name

Linux uses a combination of letters and numbers to identify hard disk partitions. The details are as follows:
Device Type of the first two letter partitions
HD: IDE Hard Drive
SD: SCSI hard disk

The device on which the third letter is partitioned
Hda: The first IDE Hard Disk
HDB: Second IDE Hard Disk
SDC: The third SCSI hard disk
Number 1-4 indicates the primary partition or extended partition. The logical partition starts from 5.
For example,/dev/hda3 indicates the third primary partition or extended partition on the first IDE hard disk;/dev/sdb6 indicates the second partition.
The second logical partition on the SCSI hard disk.
NOTE: If there is no partition on the hard disk, no number is added, which indicates the entire hard disk.

Generally, installing Red Flag Linux Desktop 5.0 requires a root file system partition (type: ext3, ext2, or
Reiserfs) and a swap partition (type: swap), this partition scheme applies to most users.
