I Don’t understand what is a tty?
Thank you. Holiday!
Once upon a time, there was a company called Teletype. They made a hard copy automatic typewriter device, which has been used as a communication terminal for decades, and then used as a hard copy computer terminal . Teletype was promoted to teletypewriters or teletypewriters to avoid using brand names.
In the beginning they were fully functional, but rather ugly…
But later models (this model 43 from the late 1970s) very beautiful…
Microprocessors made video display terminals practical. In the past, hardcopy terminals were quite cheap and more popular. As it happens, the Unix tty abstraction also applies to video terminals.
And, it is suitable for xterm windows and xterm children (usually called terminal), which can be found in other descendants of Linux, Mac and Unix…
