Title: concepts such as terminal, console, tty, and pty in Linux. Linux is a technology channel of the IT lab in China. Includes basic categories such as desktop applications, Linux system management, kernel research, embedded systems, and open source.
Basic concepts:
1> tty (collectively referred to as the terminal device ):
Tty is derived from Teletypes or teletypewriters. Originally, it refers to a telex typewriter, which reads and sends messages t

To support earlier browsers, you must stick to the css1 media descriptor screen and print. They are mutually exclusive. Therefore, when a page is generated for the screen display, the browser will ignore the print style sheet, and vice versa. Therefore, each style sheet must contain the same style selector, but there are different rule declarations to generate page styles for different output devices.

1. First declare the correct document type DOCTYPEThere are typically four document types to choose from:DOCTYPE is defined before HTML to tell the browser that the page contains HTML, XHTML, or both, so that the browser can parse the label correctly. According to research, most browsers will parse this statement in a common way, so most of them use the HTML4.01 standard.2. When writing HTML, try not to use an embedded CSS style, because doing so will cause problems in your code, so it is best t

The device Aspect Ratio describes the aspect ratio of the output device. This value contains two positive integers separated. Represents the ratio of the number of horizontal workers (the first value) to the number of vertical workers (the second value)

[5] device-height)
The device height describes the height of the output device.

Q5: Briefly describe the SSH running process?
A5: The process is as follows:
The client initiates an SSH connection request to the server.
The server initiates version negotiation to the client.
After the negotiation, the server sends the host key, public key, random number, and other information. All communications are not
