The Linux Kernel, Kernel Modules And Hardware Drivers

The standard location for all Device files in the system...
...But one can create Device files in other directories (e.g. in RedHat's installation process, the Device files for the hard disks are created in the /tmp directory).
Examples of conventional file names:
- hda - first (a) IDE Device (hard disk, CDROM).
- hdb3 - 3rd (3) partition of second (b) IDE Device (must be a hard disk. CDROMs have no partitions).
- ttyS0 - first serial port ("COM1").
- sda1 - 1st (1) partition of first (a) SCSI Device (hard-disk, an emulated SCSI Device, etc.).
- lp0 - first parallel port (LPT1).
