Compute (logical and mathematical operations), IO input/output (keyboard, mouse, screen, webcam), network transmission, data storage (file, database, etc.) is the 4 major function of the computer. Needless to say, node has to have these features. This can be regarded as a point of textual research.The other i

The difference is that the mobile browser is the world of WebKit, PC is the world of IE. Mobile Web pages can be understood as a smaller version of the PC Web page plus some touch features. Because it is a Web page development in the browser, all the final code has the characteristics of a cross-system platform.2. Web App DevelopmentSpecifically, it is developed with
