Isn't one, really. Terminal's probably the more "technically correct" term but they both make sense.

I could only get emacs to open in console so I was also wondering what are the common applications to use in console. Smilie

Anything that demands user interaction and isn't a graphical program naturally has to be in a terminal, since a terminal is the way to get interactive information from the user. Editors(nano, vi, emacs) need a terminal if you're not using a graphical version of them, and login systems in particular (su, sudo, ssh, scp, sftp) demand a terminal of one sort or another.

Shells can use terminals, when available, to give you an interactive prompt, but are quite capable of running noninteractively and without a terminal too, when running shell scripts.

I'd also point out a small but important distinction; quite a few utilities couldn't care less whether you run them in a terminal, a GUI, or no environment at all. They just do their job and don't even worry about where they are or why. Unless the command interacts with you somehow, you can be relatively sure it falls into this category... Commands like cp and mv and awk and a blizzard of other common utilities fall into that category.

So it's not really a different "kind" of program, just programs using the resources available to them in different ways.

ttys

ttys(4) 						     Kernel Interfaces Manual							   ttys(4)

NAME

       ttys - terminal control database file for trusted systems

SYNOPSIS

DESCRIPTION

       The system supports a single terminal control database containing entries for each local terminal that can log into the system. Authentica-
       tion programs use information contained in the terminal control database to determine if login from the terminal is  permitted.	Additional
       fields are maintained for informational purposes.

       The  format  of	the terminal control database file is identical to other system authentication database files. For more information on the
       file format, see authcap(4).  The file consists of keyword field identifiers and values for those fields. The keyword identifiers supported
       and their use include:

       This field defines the terminal device name for the entry. The terminal device
			 is  expected  to  be  contained  in  the  directory, therefore this prefix should not be specified. If the terminal entry
			 describes the device, the field should contain

       This field records the user id of the last user to successfully login using
			 the terminal device.

       This		 field records the last successful login time to the terminal device.

       This		 field records the last unsuccessful login time to the terminal device.

       This field records the number of consecutive unsuccessful login attempts to
			 the terminal device.

       This field specifies the maximum number of consecutive unsuccessful login
			 attempts permitted using the terminal before the terminal is locked. Once the terminal is locked, it must be unlocked	by
			 an authorized administrator.

       This field specifies the login timeout value (sec).

       This field specifies the delay between login tries (sec).

       This flag field indicates whether the terminal device has been administratively
			 locked or not. This field is manipulated by authorized administrators only.

EXAMPLES

       The following is an example of a terminal control database entry:

       This  entry  is	for the system console device, The most recent successful login session was for the user The entry records the system time
       for the current successful login and the time of the most recent unsuccessful login attempt.

WARNINGS

       Remote terminals (ptys) should not be added to the or databases.  Device name formats treated as ptys by login are:

	      where	  x is a letter, and y is a hex number
	      where	  x is a letter, and y is a hex number

	      HP-UX 11i Version 3 is the last release to support
	      trusted systems functionality.
