LESSON 1 Introduction to Information and Communication Technologies The state of ICT technologies Online systems, functions, and platforms At the end of this lesson, the students should be able to: 1. improve their knowledge on how ICT affects their everyday lives and the state of our nation; 2. compare and contrast the differences between online platforms, sites, and content; 3. understand the features of Web 2.0; 4. understand the future of the World Wide Web through Web 3.0; and 5. learn the different trends in ICT and use them to their advantage.  Information and Communication Technologies Information and Communication Technology (ICT) deals with the use of different communication technologies such as mobile phones, telephone, Internet, etc. to locate, save, send and edit information.  ICT and Society EDUCATION Source of learning, teaching, and research materials Online learning and communities Recording and computation of grades Managing records and other administrative purpose  ICT and Society ECONOMIS AND TRAVEL Online marketing Convenient business transaction Online payment gateways Online booking and reservation Online tracking of reservations  ICT in the Philippines  “ICT HUB of Asia”  Call center or BPO (Business Process Outsourcing) centers, BPM (Business Process Management), financial, health and IT sectors.  IT industry size is worth $22.9 billion dollars.  ICT in the Philippines Time Magazine’s “The Selfiest Cities around the World” of 2013 places two cities from the Philippines in the top 1 and top 9 spots. Top 10 Selfiest Cities in the World 1. Makati and Pasig, Philippines (258 selfie – 100,000 people) 2. Manhattan, New York 3. Miami, Florida 4. Anaheim and Sta. Ana, California 5. Petaling Jaya, Indonesia 6. Tel Aviv, Israel 7. Manchester, England 8. Milan, Italy 9. Cebu City, Philippines (99 selfie – 100,000 people) 10.George Ton, Malaysia  WEB 1.0: When the World Wide Web was invented, most web pages were static. Static (also known as flat page or stationary page) in the sense that the page is “as is” and cannot be manipulated by the user. The content is also the same for all users. This is referred to as Web 1.0.  WEB 2.0: DYNAMIC WEB PAGES Web 2.0 is the evolution of Web 1.0 by adding dynamic web pages— the user is able to see a website differently than others. Users can also comment and create user accounts.  WEB 2.0: DYNAMIC WEB PAGES Examples of Web 2.0 include social networking sites, blogs, wikis, video sharing sites, and web applications.  WEB 2.0: DYNAMIC WEB PAGES Web 2.0 allows users to interact with the page: instead of just reading a page, the user may be able to comment or create a user account. Web 2.0 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.  Most websites that we visit today are Web 2.0.  FEATURES OF WEB 2.0 1. Folksonomy. It allows users to categorize and classify/arrange information using freely chosen keywords (e.g., 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.  FEATURES OF WEB 2.0 2. Rich User Experience. Content is dynamic and is responsive to user’s input. In the case of social networking sites, when logged in, your account is used to modify what you see in their website.  FEATURES OF WEB 2.0 3. Long Tail. 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.  FEATURES OF WEB 2.0 4. User Participation. 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. (e.g., Amazon.com, online stores).  FEATURES OF WEB 2.0 5. Software as a Service. 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. Software as a service allows you to “rent” a software for a minimal fee.  FEATURES OF WEB 2.0 6. Mass Participation. 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 The Semantic Web is a movement led by the World Wide Web Consortium (W3C). Semantic Web is a proposed development of WWW in which data in web pages is structured and tagged in such a way that can be read directly by computers. The W3C standard encourages web developers to include semantic content in their web pages.  According to the 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. Web 1.0 , 2.0 , and 3.0  Several problems of Web 3.0 1. Compatibility HTML files and current web browsers could not support Web 3.0. 2. Security The user’s security is also in question since the machine is saving his or her preferences. 3. Vastness The World Wide Web already contains billions of web pages. 4. Vagueness Certain words are imprecise. The words “old” and “small” would depend on the user. 5. Logic Since machines use logic, there are certain limitations for a computer to be able to predict what the user is referring to at a given time.  TRENDS IN ICT 1. Convergence Technological convergence is the synergy of technological advancements to work on a similar goal or task. 2. Social Media Social media is a website, application, or online channels that enable web users to create, co- create, discuss, modify, and exchange user- generated content.  SIX TYPES OF SOCIAL MEDIA: a. Social Networks. These are sites that allow you to connect with other people with the same interests or background. Examples: Facebook and Google+  SIX TYPES OF SOCIAL MEDIA: b. Bookmarking Sites. These are sites that allow you to store and manage links to various websites and resources. Examples: Pinterest and StumbleUpon  SIX TYPES OF SOCIAL MEDIA: c. Social News. These are sites that allow users to post their own news items or links to other news sources. Examples: reddit and digg  SIX TYPES OF SOCIAL MEDIA: d. Media Sharing. These are sites that allow you to upload and share media content like images, music, and video. Examples: Youtube and Instagram  SIX TYPES OF SOCIAL MEDIA: e. Microblogging. These are sites that focus on short updates from the user. Examples: Twitter and Plurk  SIX TYPES OF SOCIAL MEDIA: f. Blogs and Forums. These websites allow users to post their content. Examples: Tumblr and WordPress 3. Mobile Technologies The popularity of smartphones and tablets has taken a major rise over the years. This is largely because of the devices’ capability to do tasks that were originally found in personal computers. KINDS OF OPERATING SYSTEMS: a. iOS – used in Apple b. Android – an open source operating system developed by Google. c. Blackberry OS – used in Blackberry devices d. Windows Phone OS – a closed source and proprietary operating system developed by Microsoft. e. Symbian – the original smartphone OS; used by Nokia devices f. WebOS – used for smart TVs g. Windows Mobile – developed by Microsoft for smartphones and pocket PCs 4. Assistive Media Assistive media is a nonprofit service designed to help people who have visual and reading impairments. A database of audio recordings is used to read to the user.
