What is a Linux terminal

The terminal is an electronic computer or a computer system. It is mainly used to allow users to input data and display their calculation results. The terminal receives keyboard input from the user and sends this input to the host system. The host system processes the user's keyboard input and commands, and the output is returned and displayed on the terminal's screen.

Linux terminal is the console of Linux. We rely on various commands to deal with the kernel to complete our daily tasks.

In the early years, computers were huge and very expensive. They were usually only used for scientific research, so it was impossible for one person to own a computer. However, computers have a lot of available resources, and usually one person uses one computer, which often results in a waste of resources. Therefore, multi-tasking and multi-users have become an important goal of computer use. Unix and Unix-like operating systems are developed with this goal in mind. Everyone uses a keyboard and monitor to connect to the computer in the computer room, and access computer resources at the same time without interfering with each other. Since there was no mouse in the early days, the Linux terminal was completely completed by the keyboard and monitor. This practice is still used today.

Terminals are classified as follows:

Physical terminal: The physical terminal corresponds to the serial port of the computer, and each serial port corresponds to a physical terminal.

Virtual terminal: With the continuous development of graphical interfaces and networks, terminals have also had a new definition. Terminals that users access through the Internet or terminals started by graphical interfaces are virtual terminals.
