Online systems, functions, and platforms LEARNING COMPETENCIES Compare and contrast the nuances of varied online platforms, sites, and content to best achieve specific class objectives or address situational challenges. OBJECTIVES At the end of the class period, the teacher should be able to: 1. give an overview of the subject Empowerment Technologies by running through the curriculum guide; 2. discuss and run through the activities in the Student Reader; and 3. introduce an exercise such as researching about ICT or any digital tools and asking the students to share their findings to the class. TRIVIA/GLOSSARY OF TERMS 1. Assistive Media - a component under Assistive technology (AT), which is a generic term used to refer to a group of software or hardware devices by which people with disabilities can access computers. Assistive Media is also a name of a company: “the Internet's first audio solution for persons with print reading/access barriers. The audio recordings of the literary works produced by Assistive Media are now easily accessible, on-demand, to the ever-growing number of persons with disabilities who now use the Internet.” 2. Collaborative platforms - “is a category of business software that adds broad social networking capabilities to work processes.” 3. Convergent Technologies - an extension of the term convergence, which means a “coming together of two or more disparate disciplines or technologies. For example, the so-called fax revolution was produced by a convergence of telecommunications technology, optical scanning technology, and printing technology.” Convergent Technologies also refers to an American computer company formed by a small group of people who left Intel Corporation and Xerox PARC in 1979. 4. Information and Communications Technology (ICT) - ICT is an umbrella term that includes any communication device or application, encompassing: radio, television, cellular phones, computer and network hardware and software, satellite systems and so on, as well as the various services and applications associated with them, such as videoconferencing and distance learning. ICTs are often spoken of in a particular context, such as ICTs in education, health care, or libraries. The term is somewhat more common outside of the United States. It may also be defined as, Information and Communication Technologies (ICT or  ICTs) are digital forms of communication including tools available on the Internet, such as blogging and email, as well as computer software, such as Microsoft PowerPoint and Word. Mobile Media - This refers to “media devices such as mobile phones and PDA’s were the primary source of portable media from which we could obtain information and communicate with one another. More recently, the smartphone (which has combined many features of the cell phone with the PDA) has rendered the PDA next to obsolete.5 The growth of new mobile media as a true force in society was marked by smartphone sales outpacing personal computer sales in 2011.” 5. Online systems - are online versions of information systems, which is “the process of and tools for storing, managing, using, and gathering of data and communications in an organization. An example of information systems are tools for sending out communications and storing files in a business.” 6. Social Media - “are computer-mediated tools that allow people or companies to create, share, or exchange information, career interests, ideas, and pictures/videos in virtual communities and networks.” 7. Web 2.0 - “describes World Wide Web sites that emphasize user- generated content, usability, and interoperability. The term was popularized by Tim O'Reilly and Dale Dougherty at the O'Reilly Media Web 2.0 Conference in late 2004, though it was coined by Darcy DiNucci in 1999.” 8. Web 3.0 - “a phrase coined by John Markoff of the New York Times in 2006, refers to a supposed third generation of Internet-based services that collectively comprise what might be called ‘the intelligent Web’— such as those using semantic web, microformats, natural language search, data- mining, machine learning, recommendation agents, and artificial intelligence technologies—which emphasize machine- facilitated understanding of information in order to provide a more productive and intuitive user experience.” 9. Web 3.0 - “a phrase coined by John Markoff of the New York Times in 2006, refers to a supposed third generation of Internet-based services that collectively comprise what might be called ‘the intelligent Web’— such as those using semantic web, microformats, natural language search, data- mining, machine learning, recommendation agents, and artificial intelligence technologies—which emphasize machine- facilitated understanding of information in order to provide a more productive and intuitive user experience. Information Sheet 1.1.-1 ICT– Information and Communication- It deals with the use of different communication technologies such as mobile phones, telephones, Internet to locate, save, send and edit information It is a study of computers as data processing tools. It introduces students to the fundamental of using computer systems in an internet environment. ICT in the Philippines Philippines is dub as the ‘’ICT Hub of Asia” because of huge growth of ICT-related jobs, one of which is BPO, Business Process Outsourcing, or call centers. ICT Department in the Philippines is responsible for the planning, development and promotion of the country’s information and communications technology (ICT) agenda in support of national development. Computer – an electronic device for storing and processing data, typically in binary form, according to instructions given to it in a variable program. Internet – is the global system of interconnected computer networks that use the internet protocol suite (TCIP/IP) to link billions of devices worldwide. Means of connecting a computer to any other computer anywhere in the world via dedicated routers and servers. Sometimes called simply ‘’the Net’’, is a worldwide system of computer networks- a network of networks in which the users at any one computer can get information from any other computer. World Wide Web An information system on the internet that allows documents to be connected to other documents by hypertext links, enabling the user to search for information by moving from one document to another. It is an information space where documents and other web resources are identified by URLs, interlinked by hypertext links, and can be accessed via the Internet. Invented by Tim-Berners Lee Web Pages The web page is a hypertext document connected to the World Wide Web. It is a document that is suitable for the World Wide Web. The different online platforms of World Wide Web: 1. Web 1.0 - refers to the first stage in the World Wide Web, which was entirely made up of the Web pages connected by hyperlinks. 2. Web 2.0 - is the evolution of Web 1.0 by adding dynamic pages. The user is able to see a website differently than others. - Allows users to interact with the page; instead of just reading the page, the user may be able to comment or create user account. 3. Web 3.0 - This platform is all about semantic web. - Aims to have machines (or servers) understand the user’s preferences to be able to deliver web content. Static Web Page - is known as a flat page or stationary age 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 that is referred to as Web 1.0 Dynamic Web Pages– web 2.0 is the evolution of web 1.0 by adding dynamic web pages. The user is able to see websites differently than others e.g. social networking sites, wikis, video sharing sites. FEATURES OF WEB 2.0 1. Folksonomy- allows users to categorize and classify information using freely chosen keywords e.g. tagging by FB, Twitter, use tags that start with the sign #, referred to as hashtag.  2. Rich User Experience – content is dynamic and is responsive to user’s input 3. 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 comments, reviews and evaluation e.g. Lazada, Amazon. 4. Long Tail– services that are offered on demand rather than on a one-time purchase. This is synonymous with subscribing to a data plan that charges you for the amount of time you spend on the internet. 5. Software as a services - users will subscribe to software only when needed rather than purchasing them e.g. Google docs used to create and edit word processing and spread sheet. 6. Mass Participation– diverse information sharing through universal web access. Web 2.0’s content is based on people from various cultures. TRENDS IN ICT I. Convergence– is the synergy of technological advancements to work on a similar goal or task. For example, besides using your personal computer to create word documents, you can now use your smartphone. II. Social media – is a website, application, or online channel that enables web users 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 allows you to connect with other people with the same interests or background. Once the user creates his/her account, he/she can set up a profile, add people, share content, etc. Example: Facebook and Google+ b) Bookmarking Sites – Sites that allow you to store and manage links to various website and resources. Most of the sites allow you to create a tag to others. Example: Stumble Upon, Pinterest c) Social News – Sites that allow users to post their own news items or links to other news sources. The users can also comment on the post and comments may also be rank. Ex. Reddit and Digg d) Media Sharing – sites that allow you to upload and share media content like images, music and video. Ex. Flickr, YouTube and Instagram e) Microblogging – focus on short updates from the user. Those that subscribe to the user will be able to receive these updates. Ex. Twitter and Plurk f) Blogs and Forums – allow user to post their content. Other users are able to comment on the said topic. Ex. Blogger, WordPress and Tumblr III. 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 the tasks that were originally found in PCs. Several of these devices are capable of using a high-speed internet. Today the latest model devices use 4G Networking (LTE), which is currently the fastest. IV. MOBILE OS iOS – use in apple devices such as iPhone and iPad Android – an open-source OS developed by Google. Being open source means mobile phone companies use this OS for free. Blackberry OS – use in blackberry devices Windows phone OS – A closed source and proprietary operating system developed by Microsoft. Symbian – the original smartphone OS. Used by Nokia devices WebOS- originally used in smartphone; now in smart TVs. Windows Mobile – developed by Microsoft for smartphones and pocket PCs V. Assistive Media – is a non- profit service designed to help people who have visual and reading impairments. A database of audio recordings is used to read to the user. e.g. Yahoo!, Gmail, HotmailCloud computing-distributed computing on internet or delivery of computing service over the internet.  - Instead of running an e-mail program on your computer, you log in to a Web e-mail account remotely. The software and storage for your account doesn’t exist on your computer – it’s on the service’s computer cloud. It has three components 1. Client computers – clients are the device that the end user interact with cloud. 2. Distributed Servers – Often servers are in geographically different places, but server acts as if they are working next to each other. 3. Datacenters – It is collection of servers where application is placed and is accessed via Internet. TYPES OF CLOUDS PUBLIC CLOUD allows systems and services to be easily accessible to the general public. Public cloud may be less secured because of its openness, e.g. e-mail PRIVATE CLOUD allows systems and services to be accessible within an organization. It offers increased security because of its private nature. COMMUNITY CLOUD allows systems and services to be accessible by groups of organizations. HYBRID CLOUD is a mixture of public and private clouds. However, the critical activities are performed using private cloud while the non-critical activities are performed using public cloud.
