The file name of each hardware device in Linux

"In a Linux system, each device is treated as a file" for example, the name of the hard disk of the SATA interface is/dev/sd[a-d], where the letters in parentheses are any of the a-d, i.e./dev/sda,/dev/sdb,/DEV/SDC , and/dev/sdd The meaning of these four documents.

In addition to the first point, in the Linux system, almost all the hardware devices are in the/dev directory, so you will see/DEV/SDA,/dev/sr0 and so on the filename oh.

What about the printer and the floppy? It's/dev/lp0,/dev/fd0! Okay, what about the other interface devices? Below is a list of some common devices and their names in Linux:
