The 6th topic of the lecture was about Web Apps. This topic is one of the main topics in information technology. Before going to start this topic our respective lecturer asked us several question in order to know our knowledge about this topic. Later on our respective lecturer gave us an overview about the web Apps. As I was aware of web apps before, so when she explained it became clearer to me. 

Web Apps contains hypertext links, or highlighted keywords and images that lead to related information and it is collection of electronic documents. Then she continued her lecture by explaining about the Web application. A web application is an application that is accessed by users over a network such as the Internet or an intranet. Web applications may display, create, and manage images, audio, videos, and data which can be stored and retrieved from the Server. To carry on the next session our respective lecturer explained us about the types of web which are Static and dynamic web page. 

After that she explained the generations of the web. There are three generations of the web with the name of Web 1.0 Web 2.0 and Web 3.0. The categories of web 2.0 were also discussed in class which are online social networking, Mash ups and aggregates. Online social networking websites function like an online community of internet users while mash-up is a web site that takes different content from a number of other web sites and mixes them together to create a new kind of content. The best example for web 2.0 application technologies are XML, AJAX, Tagging’s, Blogs, Wikis, Really simple Syndication and Pod and video casting. About XML, she explained that XML is the abbreviation of Extensible Markup Language and it’s for Web Documents (2.0) and also it contains structured information including words and pictures. Another example which she described was about AJAX which derived the meaning of acronym referring to Asynchronous JavaScript and XML.

Later on, different types of PL (Programming Language) were explained by lecturers which are High level language and low level language. High level language known as, A machine-dependent language while on the other side low level language known as more user friendly or assembly language. Machine language uses a series of binary digits (1s and 0s) or a combination of numbers and letters that represent binary digits and assembly language can be define as Program is written using symbolic instruction codes and also uses symbolic memory addresses. Furthermore, she explained about the three m fourth and fifth generation language. 

 To conclude, I got very interesting information during this lecture. I believe that this lecture will be really helpful for me.
