Questions about (Pseudo)Terminal devices
 

hi

I'm learning(trying to) about Terminal and pseudo-terminal devices.

1---I've read that on unix's BSD systems files with names like /dev/ptyp0 or /dev/ptyp3 represent pseudo terminal master devices, and files like /dev/tty3 represent slave devices.

Are same files used in linux also?

2---If the above files represent pseudo terminals,then what do /dev/pts/"some number" represent?

3---Which files represent local (NON-pseudo) terminals?

4---When I log in locally,is my keyboard and display card considered a regular terminal?
I'm asking this cos I have read in linux book that as far as Linux is concerned,those two are just very fast remote terminals (meaning pseudo terminals)

I hope you can help me on this,since info about terminals is very hard to find

thank you very much
