Computer - Device management in Linux.
As with all Linux-like operating systems, Red Hat Linux uses device files to access all hardware (including disk drives, cdrom).
However, the naming conventions for attached storage devices varies somewhat between various Linux and Linux-like implementations. Here is how these device files are named under Red Hat Linux.
On typical Linux-based systems, the /dev directory is used to store file-like device nodes which refer to certain devices in the system. Each node points to a part of the system (a device), which might or might not exist.
Under Red Hat Linux, the device files appear in the /dev/ directory.
[root@ebs121 dev]# ls /dev/
agpgart floppy-fd0 null ram4 tty1 tty30 tty51 vcs1
cdrom full nvram ram5 tty10 tty31 tty52 vcs2
cdrom-hdc gpmctl oldmem ram6 tty11 tty32 tty53 vcs3
console hdc par0 ram7 tty12 tty33 tty54 vcs4
core hpet parport0 ram8 tty13 tty34 tty55 vcs5
disk initctl parport1 ram9 tty14 tty35 tty56 vcs6
