It represents a natural evolution of computing towards ubiquitous access through portable, connected devices.
Ubiquitous computing Paper
The year of the Internet of Things; The Internet of Things probably already influences your life. And if it doesn’t, it soon
will, say computer scientists; Ubiquitous computing names the third wave in computing, just now beginning. First were
mainframes, each shared by lots of people. Now we are in the personal computing era, person and machine staring uneasily at
each other across the desktop. Next comes ubiquitous computing, or the age of calm technology, when technology recedes into
the background of our lives. Alan Kay of Apple calls this "Third Paradigm" computing.
Ubiquitous computing is essentially the term for human interaction with computers in virtually everything.
Ubiquitous computing is roughly the opposite of virtual reality. Where virtual reality puts people inside a computer-generated
world, ubiquitous computing forces the computer to live out here in the world with people. Virtual reality is primarily a horse
power problem; ubiquitous computing is a very difficult integration of human factors, computer science, engineering, and social
sciences.
The approach: Activate the world. Provide hundreds of wireless computing devices per person per office, of all scales (from 1"
displays to wall sized). This has required new work in operating systems, user interfaces, networks, wireless, displays, and many
other areas. We call our work "ubiquitous computing". This is different from PDA's, dynabooks, or information at your
fingertips. It is invisible; everywhere computing that does not live on a personal device of any sort, but is in the woodwork
everywhere. The initial incarnation of ubiquitous computing was in the form of "tabs", "pads", and "boards" built at Xerox
PARC, 1988-1994. Several papers describe this work, and there are web pages for the Tabs and for the Boards (which are a
commercial product now):
Ubiquitous computing will drastically reduce the cost of digital devices and tasks for the average consumer. With laborintensive
components such as processors and hard drives stored in the remote data centers powering the cloud , and with pooled
resources giving individual consumers the benefits of economies of scale, monthly fees similar to a cable bill for services that
feed into a consumer’s phone

pervasive computing
This document discusses pervasive computing, which refers to embedding microprocessors into everyday objects to make computing available anywhere. It defines pervasive computing, describes its architecture and principles, compares it to ubiquitous computing, and discusses related fields, applications, benefits, limitations, and future directions. Pervasive computing aims to spread intelligence and connectivity through mobile devices, sensors, and other embedded technologies. It will continue affecting more people as networking allows intelligent objects to communicate and share information.
CS.pptx
The document discusses several key concepts in advanced computing techniques including networks, computing, pervasive computing, mobile computing, cloud computing, and big data. Networks allow nodes to share resources by exchanging data through connections established via cable or wireless media. Cloud computing provides on-demand access to configurable computing resources like servers, storage, databases, and applications via the internet. Big data involves extremely large data sets that are difficult to process using traditional data management tools due to their size, diversity and complexity.
Chap1 introduction to Pervasive Computing
The document discusses pervasive computing, which integrates mobile communication, embedded computer systems, consumer electronics, and the internet. It defines pervasive computing as intelligence and connectivity existing everywhere through devices. Examples provided include accessing notifications and transactions anytime from any device on any network with any data. Differences between ubiquitous and pervasive computing are defined. Pervasive computing scenarios and infrastructure are described. Applications discussed include automobiles, mobile workplaces, homes, communication environments, and location-based services. Challenges and the future of technologies like cell phones, watches, and implanted devices are also mentioned.
Mobile Computing
Mobile computing allows transmission of data, voice, and video via computers and wireless devices without a fixed physical connection. It provides wireless communication between devices through technologies like ubiquitous computing, which makes computing appear everywhere, and pervasive computing, which uses information technology everywhere. Mobile computing devices include PDAs, smartphones that combine PDA and phone capabilities, and tablets with large touchscreens. While offering location flexibility, enhanced productivity, and entertainment, mobile computing has limitations around resource constraints, interference, bandwidth, dynamic network changes, and security issues.
PERVASIVE COMPUTING
Pervasive computing involves the interaction of numerous computing devices connected via wired and wireless links. This seminar discusses pervasive computing technologies and applications, including information access, mobility and networking, perceptive interfaces, and real-time applications. It also outlines some ongoing research projects and concludes that pervasive computing continues to affect more populations through regional and cultural influences on the technologies.
Mobile computing
Mobile computing allows transmission of data without a fixed physical connection via a computer. It involves human-computer interaction and transportation of computing during normal usage. It aims to provide useful information to clients anywhere and anytime, altering lifestyles and work methods. Key aspects include mobile communication, mobile hardware, and mobile software running on handheld devices. Mobile computing is now an indispensable part of everyday life via technologies like WiFi, cellular broadband, and cloud computing.
Class 2
This document discusses mobile systems engineering and provides an overview of mobile devices, operating systems, and applications. It describes the evolution of computing from early computers to smartphones and defines key aspects of mobile systems including their portability, battery power, wireless connectivity, and associated constraints and characteristics compared to desktop and embedded systems. Examples of mobile applications and system architectures are provided. Popular mobile platforms like Android, iOS, Blackberry and Windows Mobile are compared in terms of their features, programming languages, and development tools.
MIS
The document discusses the history and applications of mobile computing. Mobile computing allows transmission of data, voice, and video through wireless devices without a fixed connection. It has a variety of uses including transmitting news, traffic information, and vehicle maintenance data. Challenges include maintaining signal strength over wireless channels and achieving high data transfer rates. Advantages are portability and cloud computing access from any location, while disadvantages include connectivity quality and security concerns. Mobile computing continues to evolve with new devices and applications.

Pros and cons of facebook
Facebook allows users to connect beyond boundaries and share thoughts, causes and ideas, which can enhance social skills. However, it can also be addictive and anti-social if overused, and raises privacy issues with information sharing. While educational, it can enable too much freedom of expression for some. On balance, it provides social benefits but also risks from oversharing and privacy leaks.

The poor man
The old man explained to the manager that he has found happiness through living simply and being content with what he has, rather than constantly wanting more. While the manager thought he must be unhappy living in a small house and owning just one truck, the farmer was happy because his simple possessions fulfilled his needs. The farmer said that true happiness comes from having a happy mind, not money or possessions, and that being content with what you have, rather than constantly wanting more, allows one to find happiness.
