Empowerment Technologies Introduction to Communication and Information Technologies Quarter 1 – Lesson 1 Information and Communication Technologies (ICT) ❖ It deals with the use of different communication technologies such as mobile phones, telephone, Internet to locate, save, send and edit information. ❖ Is a study of computers as data processing tools. It introduces students to the fundamental of using computer systems in an internet environment. 3  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. ❖ Time Magazine’s “the Selfiest Cities around the World” of 2013 places two cities from the Philippines in the top 1 and top 10 spots. The study was conducted using Instagram, a popular photo sharing application. 4 Computer ❖ an electronic device for storing and processing data, typically in binary form, according to instructions given to it in a variable program. 5 Internet ❖ is the global system of interconnected computer networks that use the internet protocol suite to link billions of devices worldwide. 6  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 7 Web Page ❖ is a hypertext document connected to the World Wide Web. It is a document that is suitable for the World Wide Web. o 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 o Dynamic Web Pages – web 2.0 is the evolution of web 1.0 by adding dynamic web pages. The user is able to see website differently than others e.g. social networking sites, wikis, video sharing sites. 8 Features of Web 2.0 1. Folksonomy ❖ allow 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 pound sign (#) This is also referred to as hashtag. 10 2. Rich User Experience ❖ 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 site, when logged on, your accounts is used to modify what you see in their website. 11 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. 12 4. Long Tail ❖ services that are offered on demand rather than on a one-time purchase. In certain cases, time-based pricing is better than file sized-based pricing or vice versa. 13 5. Software as a Service ❖ users will subscribe only when needed rather than purchasing them. ❖ users will be subscribe to a software only when needed rather than purchasing them e.g. Google docs used to create and edit word processing and spread sheet. 14 6. Mass Participation ❖ 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 culture. 15 WEB 3.0 and the Semantic Web ❖ The term was coined by the inventor of World Wide Web, Tim Berners- Lee. He noted that the semantic web is a component of Web 3.0. ❖ Aims to have machines (or servers) understand the user’s preferences to be able to deliver web content. 16  WEB 3.0 and the Semantic Web Web 3.0 is yet to fully realized because of several problems: ❖ Compatibility. HTML files and current web browsers could not support Web 3.0. ❖ Security. The user’s security is also in question since the machine is saving his or her preferences. ❖ Vastness. The world wide web already contains billions of web pages. ❖ Vagueness. Certain words are imprecise. The words “old” and “small” would depend on the user. ❖ Logic. Since machines use logic, there are certain limitations for a computer to be able to predict what17the user is referring at a given time.  TRENDS IN ICT A. 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. B. 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. 18  Six types of social media: 1. 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+ 2. 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 19  Six types of social media: 3. 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. Example: Reddit and Digg 4. Media Sharing – sites that allow you to upload and share media content like images, music and video. Example: Flickr, YouTube and Instagram 20  Six types of social media: 5. Microblogging – focus on short updates from the user. Those that subscribed to the user will be able to receive these updates. Example: Twitter and Plurk 6. Blogs and Forums – allow user to post their content. Other users are able to comment on the said topic. Example: Blogger, WordPress and Tumblr 21  TRENDS IN ICT C. 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 5G Networking, which is currently the fastest. 22  Mobile Operating Software (0S) ❖ 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 ❖ Web OS - originally used in smartphone; now in smart TVs. ❖ Windows Mobile – developed by Microsoft for smartphones and pocket PCs 23  TRENDS IN ICT D. 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. 24
