The origins and differences between carriage return and line feed.
Before the computer appeared, there was a kind of thing called teletype model 33, which also came from the TTY concept in Linux/Unix. It can contain 10 characters per second. But there is a problem, that is, when a line breaks a line, it takes 0.2 seconds, just two characters. If a new character is passed in the 0.2 s, the character will be lost.
As a result, the developers thought of a way to solve this problem, that is, adding

trouble. In fact, this is not to blame windows. \r\nThe history of use can be traced back to the distant 19th century. The typewriter, which was invented at that time, was a solid cylinder + a chrysanthemum-like font. The paper is firmly fastened to the surface of the cylinder. When we press a letter, the mechanical device "fly" to the paper, while the ribbon before the cylinder rises, hard to print, so the paper appears on a word. After printing, th

Code:

Tty is derived from teletypes or teletypewriters. Originally, it refers to a telex typewriter, which reads and sends messages through a printer keyboard through a serial line. Later, it was replaced by a keyboard and a display, so now it is more appropriate to call the terminal.But if we remotely telnet to the host or use xt

", which tells the typewriter to position the print head on the left boundary, and the other is "line feed", which tells the typewriter to move the paper down one line. Later, computers were invented, and these two concepts were invented on computers. At that time, memory was very expensive. Some scientists thought it would be too waste to add two characters at the end of each line. Just add one character.
The flash typing effect is also used in many animations, such as the AE typing effect. For example, the typewriter effect, flash typewriter effect, and premiere typing effect are easy to implement. There is also a kind of such effect: webpage typing effect. The animation typing effect can be achieved by using js on the webpage, but the flash typing effect can be more beautiful.Step 1: import a typing sound
