Web Application

Today I’m writing my last topic about ICT with a bit emotion because I’m losing one more semester from my university life but life must go on and we have to look forward towards our aim and future plan. In this semester, I have learned a lot of things that I may need during my graduation. Truly speaking, my lecturer Nur Khairunnisha Zainal is very good as a teacher and we had a fun during the lecture session and she is good at making people understand as well. From my personal point of view, ICT is one of the most important subjects that we need to improve in order to compete with others in this era of globalization. That’s why I chose ICT for my graduation course. However, I hope I will be like a cheerful bird in my coming semester. Ohhh….i forgot to ask you guys, How are you?? How are your days going??

Don’t forget to answer my questions because I will be waiting for your answers. If you answer me, I’ll feel very much blissful through the connection of our hearts.

Stop this fabulous words !! let’s go on to the topic. Today, I will explain about the Web application and Web information system.

Web Application

Web application is an application that is accessed over a network such as the internet or intranet. It may also mean a computer software application that is coded in a browser-supported language and reliant on a common web browser to render the application executable.

It is also defined as a collection of logically related interactive functions that fulfill a specific business requirement as defined by a knowledgeable user of the Internet. In the case of a web application, the ‘business user’ of the application is the web provider, and it is the view that determines what ‘user requested functionality’ is. The end-user of the web site does not directly influence either the business functionality provided, or the design requirements.

The architecture of web applications comprises multiple components. The purpose for counting, determines which components are to be included within the scope of a particular count. Examples of web components include:

• Business Application functionality
• Security
• Browsers (explorer, chrome)
• E-mail component
• Bulletin Boards

Web 2.0 Application

•      Dynamic interactive web sites

•      Typically with client / server communication patterns

•      Famous for E-Commerce applications

Advantage of Web application

•         Easy to use (end-user focused)
•    Familiar: frequent use of standard controls
•       You don’t need a manual to use them!
•    Platform and machine independent
•     No installation on client machine
•    Easy to update (hit refresh!)

Web information system

Web information system is an information system that uses internet web technologies to deliver information and services, to users or other information systems. It is a software system whose main purpose is to publish and maintain data by using hypertext based principles.

Web information system usually consists of one or more web applications, specific functionality-oriented components, together with information components and other non-web components.

Different Types of WIS

• •      Informational

-       Disseminate information (static or dynamic)

-       Share information (among visitors or WISs)

• •      Transactional

-       Conduct transactional business (B2C, C2C, B2B…)

-       Perform tasks (simple, complex and collaborative)

Finally we have learned about Google applications such as Google document, Google calendar, Gmail, Google site etc.

The most satisfactory conclusion that I can draw is that I feel very pleased to fulfill this course and I have erudite a lot of things.

Special thanks to my Lecturer Nur Khairunnisha Zainal to teach us everything very clearly with a friendly mood. I also want to thanks all the readers from my heart and beast of luck everyone..:)

Internet

Hello world !!! Today I am going to explain about the internet and World Wide Web that is very popular to everyone nowadays. Without wasting time let me proceed on.

WWW and Internet are two widely known and used terms. This is the age of the internet and billions all over the world make use of it daily for various purposes. However, a vast majority of people think that World Wide Web and internet are synonyms. They tend to use the terms interchangeably which is wrong. Though the terms are related, there are differences between the two.

Internet is a massive network of networks that connects millions across the globe daily. It helps create a network in which anyone sitting in any remote corner of the world can get connected to any other person thousands of miles away. The only requirement for these two people to connect with each other is a computer and an internet connection. Millions of websites containing a sea of information are there on the internet and this information travels at the speed of light literally through various languages known as protocols.

On the other hand, WWW is a way of getting to the information available on the net. It is a model for sharing information that sits atop internet. The World Wide Web makes use of HTTP protocol, which is one of the languages used over the net to transmit information. The web utilizes browsers such as Chrome, Internet Explorer, and Firefox to get access to millions of web pages. These pages are liked to each other via hyperlinks in an amazing manner. It is not just text; web pages are full of graphics, images as well as videos.

It is thus clear that web is just a subset of the internet and not a synonym of internet. Though closely related, the two terms cannot be used interchangeably.

Today Internet and WWW continues growing day by day and it can be shown below by having a look at the graphs.

It signifies a conversation between the original author of the content and all those who can comment or participate. It refers to the transition from static HTML web pages to a more dynamic HTML or dynamic web. It is also regarded as the social web for example Ex-Wikipedia, Face book, YouTube, all online affairs of government as well as private entity.

Combined with the social web 2.0 services, web 3.0 provides the internet user with the opportunity to engage with people all over the world on a variety of devices such as Ex-Twitter, 3G Cellular, Wi-Fi-network, iPhone, one ta-local movie listings and trailers.
