Do you know that what is the difference between the console terminal and terminal?

Thanks

The console can be used as a 'HP' Terminal or as vt100 (EM100)

Typically a terminal if it is of a serial connectivity nature, connects to either a terminal server or into a mux. If your using a PC for example you will most likely be using some form of terminal emulator, which is different.

The console TERM is designed to work with a serial console. Its usually set to hp or em100.

terminal is a series of escape codes and such designed to work with particular terminal types.

Other terminal types are designed to work with other terminals.

In the end I've used vt100 with almost every terminal type, console and software so the difference may not be so practical.

A terminal = any device that's not very useful as a computer by itself, but can display/print output from a computer and allow the user to send some sort of input to the computer. Can also be an actual computer that's just pretending to be a terminal (using a terminal emulator software).

A console terminal (in unix sense) = any terminal that's connected to a (unix) computer and configured in such a way that the sysadmin can use it to monitor the computer's startup and access the computer in a single-user mode (or any other maintenance mode). May grant some special privileges to the administrator: on HP-UX, the "root" user can login on the console even if all the passwords are expired.

Terminal is the connectivity and working environment on the system. It is varying depends upon the user mode.

console - is used for privillaged super user. It is the key terminal to control the manage the system and having all permissions to do.

terminal - It is for normal users who can can do the changes / accessings based on the privillage level

All terminal allocations are done on /etc/inittab file.

We can get the currect tty using getty command.

TTY configurations are made on /etc/gettydefs file. You can know over man gettydefs

We can control the login based on the terminal types. If you want to block the super user login,

create a file as,.

--- /etc/securetty --
console
-------------------

chmod 600 /etc/securetty

It will block the super user login. See more over login man page.
