Summary of Linux endpoints and Shell

Early computers because you understand the reason there are multiple physical terminals (by connecting the port of the computer what to achieve), here the terminal is the I/O device. The computer itself, which is inherently an I/O device (not an external connection), is called the console console.

Now the concepts in the Linux system are as follows:

Physical Terminal: The system is not running after the virtual terminal (is a program) before the state, also known as the console console.

Virtual Terminal: By the program to virtual out of the terminal, the early computer model emulation, Linux has 6 (not even graphics terminal), you can switch to each other. The virtual terminal runs on top of the physical terminal.

Analog Terminal: 1, remote shell Landing terminal. 2. Start the shell terminal in the graphics terminal

Shell: The software interface that the computer interacts with the user, the shell program runs after the terminal runs, and a shell corresponds to a terminal. The shell is divided into graphics and command line two kinds.

Serial terminal: Connect the terminal of computer serial port (do not understand, understand slowly later).

This is my first blog post, if there is a mistake welcome to point out.
