Web Applications

This was the last lessons and it was about the web and applications.
A web application is an application that is accessed by users over a network such as the Internet or an intranet The term may also mean a computer software application that is coded in a browser-supported programming language (such as JavaScript, combined with a browser-rendered markup language like HTML) and reliant on a common web browser to render the application executable.
Web applications are popular due to the ubiquity of web browsers, and the convenience of using a web browser as a client, sometimes called a thin client. The ability to update and maintain web applications without distributing and installing software on potentially thousands of client computers is a key reason for their popularity, as is the inherent support for cross-platform compatibility. Common web applications include webmail, online retail sales, online auctions, wikis and many other functions.

E-Business.

E-business is the term to describe the information systems and applications that support and drive business processes, most often using the World Wide Web. E-business allows companies to link the internal and external processes more efficiently and effectively, and work more closely with suppliers and partners to better satisfy the needs and expectations of their customers. With e-business you can communicate across the country with customers, or simply using email to broadcast product news and information. 

Examples of business-to-business exhibitions are those in the areas of health care, computer products, electronics, advertising specialties, heavy equipment, agriculture, fashions, furniture, and toys.

We also studied about E-commerce, online shopping, E-banking, web2.0, and web 1.0 and the difference and features of each of them. The lecturer explains clearly and particularly about this terms supported with example from our daily life.

  

By this post I end reflecting in all what I have learned about in the computer and Internet course, even though it seemed very general and simple, but I admit that I have learned new things and enjoyed.

 Finally, I would like to thank my lecturer Mr.Azamuddin Abdul Rahman  for his hard work and effort to make the information available and understandable for us all.
