• ICT refers to technologies associated with the transmission and exchange of data
• World Wide Web (WWW) refers to the pages seen when at a device and online
• Internet is a network of connected computers that the web works on
• WWW uses three protocols:

  • HTML (Hypertext Markup Language): language for writing web pages
  • HTTP (Hypertext Transfer Protocol): requests the HTML document from the server and serves it to the browser
  • URL (Uniform Resource Locator): the address indicating where a document lives on the web, defined as <protocol>://<node>/<location>
• Web 1.0:

  • First-generation web
  • Static and monodirectional read-only web
  • Began as an information place for businesses to broadcast information
  • Limited user interactions and content contributions
  • Main goal was to publish information for anyone at any time
  • Users surfed the web for information without interacting with sites in terms of returning user-generated data
• Web 2.0:

  • Dynamic and bi-directional
  • Known as wisdom web, people-centric web, participative web, and read-write web
  • Allows assembling and managing large global crowds with common interests in social interactions
  • Users have more interaction with less control, flexible web design, creative reuse, updates, collaborative content creation and modification
  • Supports collaboration and gathering collective intelligence
  • Examples include social networking sites, blogs, wikis, video sharing sites, hosted services, and web applications
• Web 3.0:

  • Semantic web
  • Aims to decrease human tasks and decisions by providing machine-readable contents
  • Includes semantic technologies and social computing environment
  • Makes the web readable by machines to improve data management, support mobile internet accessibility, simulate creativity and innovation, encourage globalization phenomena, enhance customer satisfaction, and organize collaboration in the social web
  • Internet can predict the best possible answers to user's questions by learning from previous choices
• Web 4.0:

  • Symbiotic web where human mind and machines interact in symbiosis
  • Read-write-execution-concurrency web with intelligent interactions
  • No exact definition yet, an underground idea in progress
• Features of Web 2.0:

  • Folksonomy: allows users to categorize and classify information using freely chosen keywords (e.g., tagging)
  • Rich user experience: dynamic content responsive to user's input
  • User participation: users can put content on websites
  • Software as a service: users subscribe to software only when needed
  • Mass participation: diverse information sharing through universal web access
• Webpage: a document commonly written in HTML viewed in an internet browser
• Website: a collection of linked pages sharing a unique domain name
• Web browser: application program displaying WWW documents
• Web server: stores and delivers website content to those who request it
• Search engines:

  • Answer machines used to discover and understand internet content
  • Primary functions are crawling, indexing, and ranking
  • Crawling: scouring the internet for content
  • Indexing: storing and organizing content found during crawling
  • Ranking: providing the most relevant results to search inquiries
• Convergence: the synergy of technological advancements to work on a similar goal or task
• Social media: online channel that allows users to create and share content, and communicate with others
• SIX TYPES OF SOCIAL MEDIA

  • Social network
  • bookmarking sites
  • social news
  • media sharing
  • Microblogging
  • blogs and forums
• Social networks are sites that allows you to connect with other people with the same interests
• Bookmarking sites allows you to store and manage links to various websites and resources
• Social news are sites that allow users to post their own news items and other sources
• Media sharing are sites that allows you to upload and share media content like images
• Microblogging are sites that focus on short updates from the user
• Blogs and Forums are websites allow users to post their content. Other users are able to comment on the said topic
• MOBILE OPERATING SYSTEMS

  • Ios
  • android
  • blackberry os
  • Windows phone os
  • Symbian
  • webos
  • Windows mobile
• iOS: used in Apple devices such as the iPhone and iPad
• Android an open-source operating system developed by Google. Being open source means several mobile phone companies use this OS for free.
• Blackberry OS used 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: smart TVs originally used for smartphones; now used for
• Windows Mobile: developed by Microsoft for smartphones and pocket PCs
• Assistive media is a nonprofit service designed to assist people who have visual and reading impairments
• Artificial Intelligence, or Al, is already known for its superiority in image and speech recognition, navigation apps, smartphone personal assistants, ride-sharing apps and so much more
• Machine Learning the subset of Al, is also being deployed in all kinds of industries, creating a huge demand for skilled professionals
• Robotic Process Automation, or RPA, is another technology that is automating jobs. RPA is the use of software to automate business processes such as interpreting applications, processing. transactions, dealing with data, and even replying to emails. RPA automates repetitive tasks that people used to do.
• Edge computing can be used to process time-sensitive data in remote locations with limited or no connectivity to a centralized location. In those situations, edge computing can act like mini datacenters
• quantum computing, which is a form of computing that takes advantage of quantum phenomena like superposition and quantum entanglement
• Virtual Reality (VR) immerses the user in an environment while Augmented Reality (AR) enhances their environment
• Blockchain: Although most people think of blockchain technology in relation to cryptocurrencies such as Bitcoin, blockchain offers security that is useful in many other ways. In the simplest of terms, blockchain can be described as data you can only add to, not take away from or change. Hence the term "chain" because you're making a chain of data
