Before the computer appeared, there was a thing called a telex typewriter (the concept of TTY under the teletype Model 33,linux/unix), which can be played 10 characters per second. But it has a problem, that is, when the line is finished, it will take 0.2 seconds to hit two characters. If there are new characters coming in this 0.2 seconds, then this character will be lost.

Under Linux, the/dev directory is important and the various devices are below. Here's a brief summary:DEV is the acronym for Devices./dev This directory is important for all users. Because this directory contains all the external devices that are used in Linux systems . But this is not the driver for the external device , This is not the same as the Window,dos operating system . It is actually a port that accesses these external devices . we can easily access these external devices, and access a
