Name the device in the RedHat/dev/directory

Dev is the abbreviation of device. The/dev directory is very important to all users. This directory contains all external devices used in Linux. However, this is not the driver of the external device, which is different from the windows and DOS operating systems. It is actually a port that accesses these external devices. We can easily access these external devices, and there is no difference between accessing a file and a directory.

Device Files are generally stored in the/dev directory. Common device files are described as follows:

/Dev/HD [A-T]: ide Device

 

/Dev/SD [A-Z]: SCSI Device

 

/Dev/FD [0-7]: Standard soft drive

 

/Dev/MD [0-31]: soft RAID device
