PERVASIVE COMPUTING

1) Pervasive computing (also called ubiquitous computing) is the growing trend towards embedding microprocessors in everyday objects so they can communicate information.

2) The words pervasive and ubiquitous mean "existing everywhere." Pervasive computing devices are completely connected and constantly available.

3) As known as Ubiquitous computing

4) Pervasive computing relies on the convergence of  wireless technologies, advanced electronics and the Internet.

5) The goal of researchers working in pervasive computing is to create smart products that communicate unobtrusively.

6) The products are connected to the Internet and the data they generate is easily available.

8) A combination of technologies is used to make pervasive computing possible, such as Internet capabilities, voice recognition, networking, artificial intelligence and wireless computing.

9) Pervasive computing also has a number of prospective applications, which range from home care and health, to geographical tracking and intelligent transport systems.

10) Disadvantages of pervasive computing include frequent line connections that are broken, slow connections, very expensive operating costs, host bandwidths that are limited in nature and location-dependent data.

UBIQUITOUS COMPUTING

1) Mark Weiser is the father of ubiquitous computing;

4) ubiquitous comp URL: https://emjock.files.wordpress.com/2010/03/ubiquitous-computing.gif

5) Ubiquitous computing is roughly the opposite of virtual reality.

6) Where virtual reality puts people inside a computer-generated world, ubiquitous computing forces the computer to live out here in the world with people.

7) Virtual reality is primarily a horse power problem; ubiquitous computing is a very difficult integration of human factors, computer science, engineering, and social sciences.

9) Ubiquitous means "the state of being everywhere"

10) ubiquitous computing is best considered as the underlying framework, the embedded systems, networks and displays which are invisible and everywhere, allowing us to 'plug-and-play' devices and tools.

AMBIENT COMPUTING

1) Remember back around the turn of the century, when the resolution of a dinner party disagreement had to wait until everyone could return to their computers in order to Google the answer?

2) Now, of course, people just pull out their smartphones and look up the answer on the spot.

3) This is the first stage of an ideal called ambient findability: being able to find anything from anywhere at any time.

4) For this to work requires ambient connectivity, the ability to get online no matter where you are.

5) For now, this connectivity comes via our smartphones and wearables such as Google Glass, but in the future (so say the futurists) we’ll connect using voice-activated ambient interfaces that are seemingly everywhere and nowhere, glanceable ambient displays, and ambient devices that offer touch-everywhere surfaces.

6) The point of all this is to achieve two ideals:

  

   a) The first is ambient informatics, where information is always readily available.

   b) The second is ambient intelligence, a surrounding electronic infrastructure that responds to its environment, particularly the presence of people.

DISAPPEARING COMPUTING

1) A vision of the future is one in which our world of everyday objects and places becomes infused and augmented with information processing and exchange.

2) In this vision, the technology providing these capabilities is unobtrusively merged with real-world objects and places, so that in a sense it disappears into the background, taking on a role more similar to electricity - an invisible pervasive medium.

4) As people find more ways to incorporate these inexpensive, flexible and infinitely customisable devices into their lives, the computers themselves will gradually "disappear" into the fabric of our lives.

5) We are still a long way from a world full of disembodied intelligent machines, but the computing experience of the coming decade will be so seamless and intuitive that--increasingly--we will barely notice it.

7) The Disappearing Computer vision of the future is that computing, information processing and computers will disappear into the background, just like, for instance, electricity has done already. It's everywhere, it's useful, and we don't have to think much about it.

ANAYLYSE THE SIMILAR AND DIFFERENCES

1) The similarities of Pervasive Computing and Ubiquitious Computing

   a) Between pervasive computing and ubiquitous computing, there are similarities which are the embedded systems,  networks and displays which are invisible and everywhere, allowing us to 'plug-and-play' devices and tools.

   b) Easily available and anywhere which mean Pervasive computing and Ubiquitous computing enable us human in the world using the devices which are wireless. Besides, ubiquitous means "existing everywhere" and we should know that all  devices in either pervasive computing or ubiquitous computing enable us to communicate unobtrusively.

2) The differences between Disappearing Computing and Pervasive Computing.

   a) Disappearing computing is involves integrating computers into our everyday lives without us realising that we are  using a computer. It means, disappearing computing made us not to think much about it also kind a computing which existed already. Apart from that, Ubiquitous computing is the type of computing which focuses more on computers surrounding everyone.
