• Communication Technologies:

  -       Phones

  -       Telephones

  -       Internet

   
• Information and Communications Technology (ICT):

  • “The  Net”
• World Wide Web

  -       An information system on the internet that allows documents by hypertext links enabling the user to search for information by moving from one document to another.

  -       An information space where documents and other web sources are identified by URLs, Interlinked by hypertext links, and can be accessed via the internet
• World Wide web

  • is an interconnected public webpages system accessible through the Internet. Tim Berners-Lee invented it in 1989

• Web 1.0:

  -       When WWW was invented, most web pages were static and cannot be manipulated by the user

  -       The content is also the same for all users

  -       Static web, static page/flat page
• Web 2.0: Dynamic web pages

  -       The evolution of web 1.0 by adding dynamic web pages – the user is able to see a website differently than others

  -       Also allows users to use web browsers instead of just using their operating system. Browsers can now be used for their user interface, application software (or web applications), and even for file storage
• Web 2.0: Dynamic web pages

  • describe the present generation of the World Wide Web concentrates on its capability to provide people the means to collaborate and share information online. The second stage in the World Wide Web is the Dynamic Website. The content of the website changes. It is interactive to the user may be able to comment or create a user account. It enables increased user participation in the web.
• Features of Web 2.0

  1. Folksonomy
  2. Rich User Experience
  3. Long Tall
  4. User Participation
  5. Software as a service
  6. Mass Participation
• 1.    Folksonomy

  a.    Allows users to categorize and classify/arrange information using freely chosen keywords (eg. Tagging). Popular social networking sites such as Twitter, Instagram, Facebook, etc. use tags that start with the pound sign (#). This is also referred to as hashtag
• 1.    Rich User Experience

  a.    Content is dynamic and is responsive to user’s input. An example would be a website that shows local content. In the case of social networking sites, when logged on, your account is used to modify what you see in their website.
• 1.    Long Tall

  a.    Services are offered on demand rather than on a one-time purchase. In certain cases, time-based pricing is better than file-size-based pricing or vice versa.
• 1.    User Participation

  a.    The owner of the website is not the only one who is able to put content. Others are able to place a content of their own by means of comment, reviews, and evaluation
• 1.    Software as a service

  a.    Users will subscribe to a software only when needed rather than purchasing them. This is a cheaper option if you do not always need to use a software.

  b.    For instance, Google Docs is a free web-based application that allows the use to create and edit word processing and spreadsheet documents online. When you need a software, like a Word Processor, you can purchase it for a one-time huge amount and install it in your computer and it is yours forever.

  c.    Software as a service allows you to “rent” a software for a minimal fee.
• 1.    Mass Participation

  a.    It is a diverse information sharing through universal web access. Since most users can use the Internet, Web 2.0’s content is based on people from various cultures.
• Web 3.0 and the Semantic Web

  Semantic Web

  -       A movement led by the World Wide Web Consortium (W3C).

  The W3C standard encourages web developers to include semantic content in their web pages.
• -       According to W3C, “The Semantic Web provides a common framework that allows data to be shared and reused across application, enterprise, and community boundaries.”

  -       The aim of Web 3.0 is to have machines (or servers) understand the user’s preferences to be able to deliver web content specifically targeting the user.
• Semantics – the ability of Web technologies to understand and interpret human-generated content. Web 3.0 aims to have machines understand the user’s preferences to deliver web content, specifically targeting the user. The Internet can predict the best possible answers to your question by “learning from your previous choices.
• Several Problems of Web 3.0

  1. Compatibility
  2. Security
  3. Vastness
  4. Vagueness
  5. Logic
• 1.    Compatibility

  a.    HTML files and current web browsers could not support web 3.0
• 1.    Security

  a.    The user’s security is also in question since the machine is saving his/her preferences.
• 1.    Vastness

  a.    The WWW already contains billions of web pages
• 1.    Vagueness

  a.    Certain words are imprecise. The words “old” and “small” would depend on the user
• 1.    Logic

  a.    Since machines use logic, there are certain limitation for a computer to be able to predict what the user is referring to at the given time.

  b.    Assistive Media, this platform created to help people with disabilities access computers from the word itself “assistive.” They guide individuals with a disability like blind people by using an audio recording of the literary works.
