Some insights on web technology

In the field of software technology, Internet technology is one of the hottest parts. Now to do an ordinary website, it involves most of the Web technology: front-end display, back-end data processing, functional modules and so on. I think, also divided into two parts of the technology: Front end, back end.

Front end, that is, to show on the client platform, page content, structure and so on. This involves HTML tags, css,javascript and so on. One of the prerequisites for these technologies is the need for the client to be able to identify (the browser). In the beginning, the page only needs to show the text content, plus the simple layout, HTML is enough.

Later site content more and more, like a single page into a multi-page, you can see pictures, animations, listen to songs, watch videos and so on. So, JavaScript technology to deal with dynamic aspects of content, CSS, is probably a site contains a lot of inside pages, in order to typesetting, color processing more convenient and produced. Even dynamic aspects will help JavaScript.

So JavaScript, of course, does more than just dynamic. Website content more and more, the most important one is to add interactive features, such as forums, email these to register new users, fill in passwords and so on. At first, every single option, the entire page to reload, extremely inconvenient. Later, the Ajax technology that was carried out by JavaScript, the website evolved into a dynamic website, so the browser can do more on the Internet in a sudden. A simple Ajax example, now register a new mailbox, we will find that when you fill in a new user name, if someone else is registered, you move the mouse, you will have a small line of words reminder to write again. In the middle, is the operation of Ajax, when you fill out the background has quietly sent the information to the backend, and the database information against.

Backend, the site to be installed on the server to be accessible, so the general back end of the work is to save the site, receive the front-end sent requests to access information, return the requested information. Here is the HTTP protocol, the Internet technology is the most common protocol, basically can surf the internet depends on it. Technical aspects, Server Software technology, database technology, scripting technology and so on. And the front-end corresponding to the beginning of the site content is small, even without database, server scripting technology. But the content of the website is getting more and more complex. As a result, the server installed the database software, a list of ways to process the site data. As well as the scripting engine, today's popular php,asp.net,javaweb, and so on, these are working with the database, dealing with dynamic interaction aspects of the function.

Now the technology of the website is rich and diverse year by day, according to the actual situation, appeared a lot of technical framework, like bootstrap,jquery,react and so on. Therefore the web Aspect technology study, can not excessively specialize in php,javascripts the grammar, the object, the array and so on. To be clear about what functions to achieve in practice, there are existing technologies that can be implemented. Learn more, pay more attention to the new trend of technology development.
