TOPIC 6: web applications

firstly, there's difference between internet and web applications. internet is the biggest network in the world that connects people and organizations. moreover, it's consists of a lot of computers and when we're using internet we're may not be using world wide web. 

the web is the service of the internet and it consists of a lot of html pages on the internet. you cannot use web APPLICATIONS without internet. 

web applications

web applications are applications, services on internet, for instance, google documents, windows live hot mail, turbo tax and more. in addition, web browsers are software applications that let users to get data, and use the content located on web pages within a website. for example, mozilla firefox, google chrome, opera and more. 

web applications use the combination of:

• script
• client and server

web page consists of web document and html and there are two types of web page: static and dynamic.

•   STATIC WEB:

 - IS A READ ONLY WEB

 -JUST ALLOWS USERS TO READ THE CONTENT OF THE WEB

 -EXAMPLE WEB 1.0

•  DYNAMIC WEB

  - WEB INTERACTIONS BETWEEN PEOPLE, SOFTWARE

  - EXAMPLE: WEB 2.0 AND 3.0 

Web 1.0 design elements

Some design elements of a Web 1.0 site include:

• Static pages instead of dynamic user-generated content.
• The use of framesets
• The use of tables to position and align elements on a page. These were often used in combination with "spacer" GIFs (1x1 pixel transparent images in the GIF format.
• Proprietary HTML extensions 
• Online guestbooks
• GIF buttons,  web browsers and other products.
• HTML forms sent via email. A user would fill in a form, and upon clicking submit their email client would attempt to send an email containing the form's details.

Web 2.0 design elements

• Web 2.0 websites include the following features and techniques, referred to as the SLATES:

  Search

  Finding information through keyword search.

  Links

  Connects information together into a meaningful information ecosystem using the model of the Web, and provides low-barrier social tools.

  Authoring

  The ability to create and update content leads to the collaborative work of many rather than just a few web authors. In wikis, users may extend, undo and redo each other's work. In blogs, posts and the comments of individuals build up over time.

  Tags

  Categorization of content by users adding "tags"—short, usually one-word descriptions—to facilitate searching, without dependence on pre-made categories. Collections of tags created by many users within a single system may be referred to as "folksonomies" (i.e., folk taxonomies).

  Extensions

  Software that makes the Web an application platform as well as a document server. These include software like Adobe Reader, Adobe Flash player, Microsoft Silverlight, ActiveX, Oracle Java,QuickTime, Windows Media, etc.

  Signals

  The use of syndication technology such as RSS to notify users of content changes.

                                                Usage of Web 2.0 

   A third important part of Web 2.0 is the Social web, which changed the way people communicate. The social web consists of a number of online tools and platforms where people share their perspectives, opinions, thoughts and experiences. 

• Podcasting
• Blogging
• Tagging
• Curating with RSS
• Social bookmarking
• Social networking
• Web content voting

                             

There are two categories of web 2.0 sites: 

1.  Online Social networking-Facebook, Twitter and more 
2.  Mash-ups and aggregators- mixture of video, social networking, data   search and news aggregators.

 Programming languages used in web 2.0 are AJAX and XML and a   programming language is a set of words, abbreviations, and symbols that  enables a      programmer to communicate the instructions to a computer and is a  language for a programmer used  to communicate with a   computer.

In this week we also had an activity of presenting our website. So every group had to present their own website and that was very interesting,moreover, I learnt how to create my own website using google site. And the teacher asked questions about the IS of the organization we have created. This helped us to know more about the IS and the importance of IS.

There are two types of programming language:
1. low level language uses machine language and assembly language.
2. high level language uses is easier to use and there are three generations of HLL: 3rd,4th,5th generations.

to conclude, during this course i have learnt many useful things about it and ict and i would like to thank our respected teacher for her support and teaching. moreover, i believe that the knowledge she gave  will greatly assist me in the future when i continue studying on my Ugp. 

So goodbye for now and take care everybody!!!!
