NI UNIT 4

• it revolutionized the computer and communications world like nothing before.

  Internet
• once a world-wide broadcasting capability, a mechanism for information dissemination, and a medium for collaboration and interaction between individuals and their computers without regard for geographic location (Leiner et al)

  Internet
• computer scientists began to write about the creation of a network of interconnected computers where scientists could share and analyze data by interacting across the network.

  1960
• refers to the global seamless  interconnection of networks made possible by the protocols devised in the 1970s through DARPA-sponsored research.”


  internet
• a computer network consisting of a worldwide network of  computer networks that use the TCP/IP network protocols to facilitate data transmission and exchange


  internet
• the academic community beyond the computer scientists, was given access to the Internet.

  1985
• programmer at CERN (European Council for Nuclear Research), wrote “Information Management: A proposal”.


  Tim Berners-Lee
• This paper would lead to the development of the first hypertext protocol

  “Information Management: A proposal”
• HTTP


  Hypertext Transfer Protocol
• WWW


  World Wide Web
• Marc Andreessen and Eric Bina at the University of Illinois developed this browser that provided graphical interface for users.


  Mosaic
• the network of interconnected computers across globe.

  internet
• application that supports a system of interlinked, hypertexted documents.

  web
• One uses the Internet to connect to the Web
• A Web browser allows the user to  view Web pages that contain text, images, and other  multimedia.
• first iteration of the Web, allowed users to access information and knowledge housed on Web pages complete with text, images, and even some multimedia. It was considered a dissemination vehicle that democratized access to information and knowledge.


  Web 1.0 (1991 - 2004)
• the world suddenly became flat as noted by

  Friedman (2005)
• transition from an information dissemination platform to an engaging, customizable, social and media-rich environment.

  Web 2.0 (2004- present)
• “the Web was shifting from being a medium, in which information was transmitted and consumed, into being a platform, in which content was created, shared, remixed, repurposed, and passed along.” as stated by

  Downes (2005)
• What web is this “the Web was shifting from being a medium, in which information was transmitted and consumed, into being a platform, in which content was created, shared, remixed, repurposed, and passed along.”

  Web 2.0
• Dark side of Web 2.0 is the increasing centralization of the web (information) which is anti-human.
• World Wide Web will become decentralized and the flow of information private, yet open. It will keep users from being exploited as they will control their personal data.


  Web 3.0 or Semantic Web
• Read-only static


  Web 1.0
• Read-write Interactive 


  Web 2.0
• Read-write-trust Verifiable 


  Web 3.0
• An environment that “offers new ways to connect things that were previously considered disparate and ‘un-connectable’: people, resources, experiences, diverse content, and communities, as well as experts and novices, formal and informal modes, mentors and advisors.”

  Connected Age
• Also variously known as the network society, the 4th Industrial Revolution, or the Age of Participation.


  Connected Age
• Mechanization, steam power, weaving loom

  Industry 1.0
• Mass production, assembly line, electrical energy

  Industry 2.0
• Automation, computers and electronics

  Industry 3.0
• cyber physical systems, internet of things, networks

  Industry 4.0
• Connected Health


  Encompasses terms such as wireless, digital, electronic, mobile, and tele-health and refers to a conceptual model for health management where devices, services or interventions are designed around the patient's needs, and health related data is shared, in such a way that the patient can receive care in the most proactive and efficient manner possible. In this model, patients, caretakers, and providers are 'connected' by means of timely sharing and presentation of accurate and pertinent information regarding patient status through smarter use of data, devices, communication platforms and people
• An umbrella term to lessen the confusion over definitions of telemedicine, telehealth and mHealth. It is an emerging disruptive technology that has the potential to transform the healthcare delivery system

  Connected Health
• intersection of high tech and high touch.


  Connected Care
• Combination of the IoT and Connected Age, thus, “intelligent connection of people, 


  Internet of Everything (IoE)
• success of any technology depends on how deeply it shapes the human experience.

  High tech/high touch approach
• Disruptors Revolutionizing Healthcare

  1. Personalized medicine 2. Consumerism 3. Digital revolution
  2. 4. Regulatory change
  3. 5. Amazon effect
• this means doctors can customize treatments based on your unique body and genetics, making them more effective.

  Personalized Medicine
• You have more say in your healthcare decisions now. You're like a customer, choosing what's best for you

  Consumerism
• Healthcare is getting more tech-savvy. Think about video calls with your doctor, health apps, and devices that track your fitness.
