What Is The Need Of Web Development?

Our time is a glowing progress can not surprise anyone very well presented in the text and images on your site. And the requirements that websites must meet have changed a lot, now make the company successful on the Internet (and this is what you develop your site, right?) You have your visitors the features and possibilities: a feedback tool, subscribe to mailing lists, RSS feeds, search facilities and so on and so forth.

Can not be achieved using commo
HTML HTML is a markup language for creating hyperlinks, insert images, tables, etc. Let's take a simple example. By using the Hypertext Markup Language, you can create a form for requesting quick and easy. This module has all the necessary attributes: text input field, the submit button. But what happens when you click on this button? In most cases - nothing at all. Do not have a sequence set of actions that must be done to get the result. Thus, a component of an interactive web development (web programming).

Take a closer look at web development and try to understand why we need it.

Web development is done using special software tools - scripts. These software tools are divided into two main types: server-side scripts and client-side scripts. Server-side scripts run on the server side, ie the computer where the site is located. They carried out before the site of the load on the user's computer pages. In turn, client-side scripts run on the client computer when the page is loaded from the server and require no additional page refresh.

What are the most common technologies for web development?

Client-side scripts are usually developed using these programming languages and application frameworks such as JavaScript, VBScript, Silverlight, Adobe Flash, etc. For example, to use JavaScript or VBScript on a website, you do not need plug-ins or additional software - you can simply paste the script into the HTML on the site since. The script is executed directly in the browser of the user, if the client computer will not need additional software. What can JavaScript do? With its help you can track all visitors actions and respond to, for example, the accuracy of information entered on the form to the right of checking browser without having to download information about the server and wait for the answer .

What server-side scripting technologies for the most popular technologies PHP, Perl, and ASP.NET.

PHP web programming language is widely known and actively used due to its simple syntax, high performance and support for most hosting services. As JavaScript is a PHP script simply inserted into the code of a HTML page and it does not require additional browser extensions to run. Many content management systems (CMS) (eg WordPress) is written in PHP.

ASP.NET is a technology developed by Microsoft Corporation and managed the Microsoft Windows operating system, Perl technology was designed for Unix operating systems. Both are quite popular of these techniques is the use of the site to handle thousands of requests per day.

This use of a technology for web development (both client-side or server-side one), a developer can enrich the site of its various interactive services, which include:

* Analysis tools (postal forms, guest books);

Dissemination tools * (for sending price lists, new);

* Content management (CMS);

* Menu items animated backgrounds, commercial;

* The search tools;

* Tools for online communication (chat);

* Polls, etc.
