Disadvantages and advantages of web 2 + some technology

There are some advantages and disadvantages of using web 2.0.

Advantages – with the use of web 2.0, information can be received from various places. People will have their freedom of speech and can express their ideas freely. Web 2.0 has made the internet more personalized and now you can talk all over the world. Now the people with low levels of computer skills can also use it easily.

Disadvantages- it leads to low quality of the actual content. As most of the services are free, the security is very low and the websites can be easily targeted by the hackers.

Web 2.0 and technology: Ajax technology is behind Web 2.0. It is creating the desktop experience in the browser again. It consists of writing JavaScript that manipulates the Document Object Model (DOM) of the host page, uses Xml Http Requests and callback objects to send and receive data asynchronously. Maintaining a JavaScript code base for large- scale applications is a major concern

In web 2.0, you require things instantly, for that we can think of tools such as Joomla or Drupal which allow to establish a web 2.0 website quickly with all sorts of functions in it such as blogs, forums, surveys, Google gadgets. This functionality is already prebuilt and minimal effort is needed to set up and run the site but you need to have complete control over the user interface (UI) and also need to configure fine – grained security.
