The Linux console (and Linux virtual consoles) are implemented by the VT (virtual terminal) subsystem of the Linux kernel, and do not rely on any user space software. [3] This is in contrast to a terminal emulator , which is a user space process that emulates a terminal, and is typically used in a graphical display environment.
It enables full POSIX compliance for certain Microsoft Windows products. [ citation needed ] Windows Subsystem for Linux , also known as WSL, is a compatibility layer for running Linux binary executables natively on Windows 10 and 11 using a Linux image such as Ubuntu, Debian, or OpenSUSE among others, acting as an upgrade and replacement for ...
In the lower right we can see a terminal emulator running a Unix shell, in which the user can type commands as if they were sitting at a terminal. In computing, a shell is a computer program that exposes an operating system's services to a human user or other programs.

A terminal mode is one of a set of possible states of a terminal or pseudo terminal character device in Unix-like systems and determines how characters written to the terminal are interpreted. In cooked mode data is preprocessed before being given to a program, while raw mode passes the data as-is to the program without interpreting any of the ...
The term DAC is commonly used in contexts that assume that every object has an owner that controls the permissions to access the object, probably because many systems do implement DAC using the concept of an owner. But the TCSEC definition does not say anything about owners, so technically an access control system doesn't have to have a concept ...
