                     Web Applications 

     Al-hamdulillah finally we are in the last topic of this subject for this trimester which is all about web apps. In this topic as usual we started the definition of the internet quite related with the web which is the biggest network on the world that connects thousands of people and organization around the world and in addition web is the collection of the electronic documents. In that lecture hall my lovely teacher asked us to checked our knowledge that whether web and internet are the same or not. Afterwards, she explained us properly the difference among web and internet. What I have learnt from this lecture which web is the service in the internet when the internet the largest network in the world. So, to use the world wide web we have to use the internet, in addition to use the internet we don't have to use the web always.

     To be continue our respective lecturer also explained us about the definition of the web page. Usually a web application refer to all service or application on the internet. Whatever a web application can create, manage and display the video, audio or images that we can store from the server. As a great example of the web application is Facebook, Google documents, website and so on. To finish early our topic she continued with about the working process of the web application. At first started from the defining that website is the collection of document in addition web page is the simple web document consisting of the text and HTML tag. There are two types of web exists in the internet world one is static and another one is dynamic web page. Static webpage is the simple web page that only allow people to read. In this web page only the people who have knowledge about the web that person can update. The great example for this webpage is educational webpage, companies webpage and so on. Whatsoever, In the dynamic webpage user can upload and also comment in this webpage. As a example of dynamic webpage is content management system, discussion board and many more.

     During having this session we have learnt also about the generation of the web. As I became to knew that the generation of the web is divided into three generation. At first which is called as web 1.0, secondly that call as web 2.0, lastly which is called as web 3.0. During the first generation the information provided on the web was static content and the web is the in HTML coding. In web 1.0 bookmarking and hyper linking was two most important aspect of this web. Then the next generation is in web 2.0 that have the familiarity for the advance internet, technology and application. It's provides ability of external editing for example web users may extend, undo and redo each others work such as in blogs, posts and the comments of individuals are displayed, shared or managed and so on. 

  So far, now we are in processing with the types of programming language. She described us properly to understand more. Firstly, she taught us that programming language is two types such as low level language and high level language. Low level language is more dependent language and it consists of another two types of language which are machine language and assembly language. Machine language is the serious of the binary digits. In addition assembly language is programme that written using the symbolic codes. It's also uses the symbolic memory address. Whatsoever, return back to high level language (HLL) which is more users to friendly language. There are three generation of this language which are third generation PL, fourth generation PL and fifth generation PL. Third generation language also as known as procedure language and the one of the best example of this language is FORTAN - C, COBOL -C++, BASIC, Pascal ActiveX and so on. Fourth generation language is also known asnon-procedural languages. The example of fourth generation is visual basic (VB) and visual age. As the last one is as known as fifth generation language which is object-oriented and web development tools. Prolog, AJAX and JAVA script are the best example of the fifth generation language.
