Because multiple users can use the system, even in the same time (and each of them can run multiple processess). It has nothing to do with the virtual terminals (Alt+F1..Fn) -- those aren't meant to be used be different people. Usually there is many remote users and zero or one local user; the remote users use telnet/ssh/rlogin or special programs such as smtp, ftp, httpd etc

They switch between virtual terminals / X-terminals. They are all for the single local user's convenience.

You can run different programs on them. Eg:

#1: mcedit program.c
#2: make
#3: man printf
#4: man scanf
#5: /usr/games/robots

No idea. I think you should ask a HW expert, but I guess it will cost you much more than buying six normal PC.

Hi Nevem,

Currently we are accessing Linux OS computer through SSH from other computers(Monitor + CPU).
But now i want to use Multiuser functionality of Linux so i am planning to access linux Computer
through monitors + keyboard only. is it practically possible ?

Perhaps possible, but quite likely very expensive. Especially if it is only for experimenting.

PS: Yet another way to use your linux box remotely: X protocol (eg:http://mobaxterm.mobatek.net/)

Hi Nevem,

As you said earlier that Virtual Terminal "Clrl + Alt + F1 to 12 only usable for Single user who are currently working.
am i right ? there are no involvement of other users...............

Second question, how many users access single Linux OS Graphically mean to say GUI mode ?

Why, can you imagine two or more people using the same keyboard and monitor taking turns in every few seconds? Well, I cannot.

There are many possibilities:
- you can run two (or more) X-sessions on two (or more) monitors
- one X-session can cover two (or more) monitors
- you can run more than one X-sessions with only one monitor (and switch between them with Ctrl+Alt+F6,F7,...)

+1: X protocols allow you to run GUI-programs remotely (eg: you can play with ksokoban or xbill on a Windows PC)
