Popular saying: LOVE MAKES THE WORLD GO ROUND • But before you start looking for someone to fall in love with…… • It is the INTERNET that made the world go round for decades.

INFORMATION AND COMMUNICATION TECHNOLOGIES (ICT) • Deals with the use of different communication technologies such as: • Mobile phones • Telephone • Internet • etc

INFORMATION AND COMMUNICATION TECHNOLOGIES (ICT) • To locate • Save • Send • Edit information

• When we make a video call, we use internet • When we send text or make a call, we use cellular networks • When we run out of load or battery, we use payphones which uses telephone network. • Having a unified way to communicate is one of the goals of ICT. • In terms of economics, ICT has saved companies a lot of resources (time and money) with the kind of communication technology they use, nowadays. • In a similar way, we spend less because of ICT. • It normally cost us a peso to send a text message or SMS, with the internet, we can send multiple messages and only be charged by a fraction.

ICT IN THE PHILIPPINES • Dub as the “ICT Hub of Asia”. • It is no secret that there is a huge growth of ICTrelated jobs around the country, one of which is the call center or BPO (Business Process outsourcing) centers • According to the 2013 edition of Measuring the Information Society by the International Telecommunication Union, there are 106. 8 cellpones per 100 Pilipinos in the year 2012.

• In a data gather by the Annual Survey of Business and Industries, NSO in 2010, the ICT industry shares 19. 3% of the total employment population here in the Philippines. • Time Magazine’s “The Selfiest Cities around the World”of 2013. . Two cities from the Philippines is in the top 1 and top 10 spots. The study conducted using Instagram, a popular photo sharing application. • No doubt that the Philippines is one of the countries that benefits most out of ICT.

Web 2. 0: Dynamic Web Pages • When the World Wide Web was invented, most web pages were STATIC. • Static (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 the users. • Referred to as Web 1. 0

Web 2. 0 • Is a term coined by Darcy Di. Nucci on January 1999. in her article titled, : ”Fragmented Future” • She wrote • the Web we know now, which loads into a browser window is essentially static screenfuls is only an embryo of the Web to come. The first glimmerings of Web 2. 0 are beginning to appear, and we are just starting to see how that embryo might develop

• Web 2. 0 is the evolution of Web 1. 0 by adding dynamic web pages-the user is able to see a website differently that others. • Examples of Web 2. 0 include social networking sites, blogs, wikis, video sharing sites, hosted services, and web applications. • 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 interface, application software (r web applications), and even for file storage. Most websites that we visit today are Web 2. 0

Features of Web 2. 0 • 1. Folksonomy- allows users to categorize and classify/arrange information using freely chosen (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 as hashtag

Features of Web 2. 0 • 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 sites, when logged on, your account is used to modify what you see in their website. •

Features of Web 2. 0 • 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. Some websites allow readers to comment on an article, participate in a poll, or review a specific product (e. g. , Amazon. Com, online stores) •

Features of Web 2. 0 • 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 size-based pricing or vice versa. This is synonymous to subscribing to a data plan that charges you to the amount of time you spent in the Internet, or a data plan that charges you for the amount of bandwidth you used. •

Features of Web 2. 0 • 5. Software as a Service – users will subscribe to a software when needed rather than purchasing them. This is a cheaper option if you do not always need to use software. For instant, Google Docs is a free webbased application that allows the user 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. Software as a service allows you to “rent” a software for a minimal fee. •

Features of Web 2. 0 • 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 cultures. •

Web 3. 0 and the Semantic Web The Semantic Web is a movement led by the World Wide Web Consortium (W 3 C). The W 3 C standard encourages web developers to include semantic content in their web pages. The term was coined by the inventor of the World Wide Web, Tim Berners-Lee. Lee also noted that the Semantic Web is a component for Web 3. 0.

Web 3. 0 and the Semantic Web • According to the W 3 C, "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.

Trends in ICT • As the world of ICT continues to grow, the industry has focused on several innovations. • These innovations cater to the needs of the people that benefit most out of ICT. Whether it is for business or personal use, these trends are the current front runners in the innovation of ICT.

1. Convergence • Technological 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. It can also use cloud technologies to sync files from one device to another while also using LTE technology which means you can access your files anytime, anywhere. Convergence is using several technologies to accomplish a task conveniently.
