What is Ubiquitous Computing ?

Hello, everyone.

First of all I would like to clarify what is Ubiquitous Computing. This term can be so confusing even to some computer science specialists. Trust me! 

It might be difficult to explain in simple words. Though not all computer science students get to play with it, many might touch some part of it even without realizing.

Actually, I created this website to better understand this and similar terminologies myself. Also I plan to keep track (not definitive) of news, achievements, devices and other stuff that I find interesting and related to Ubiquitous Computing.

In my case if someone asked me "What is Ubiquitous Computing ?" - I would try to answer in simple words saying "It is an environment where different kind of embedded electronic devices that have smart sensors are installed into our daily used objects. Those everyday objects, at first sight, might not necessarily look like they have technical/electronic parts within them, but . It is not necessary that they are connected and aware of each other, because they might have different protocols. But they should be connected to either internet or intranet, and should generate some type of output data from their sensors ". This would be my interpretation of Ubiquitous Computing. It doesn't necessarily look complete or precise, but at least I tried...

Also I would like to give another definition of Ubiquitous Computing from more reliable source. 

" Ubiquitous Computing (also called as Pervasive Computing) is the growing trend towards embedding microprocessors in everyday objects so they can communicate information.  The words pervasive and ubiquitous mean "existing everywhere." Pervasive computing devices are completely connected and constantly available.

Pervasive computing relies on the convergence of wireless technologies, advanced electronics and the Internet. The goal of researchers working in pervasive computing is to create smart products that communicate unobtrusively. The products are connected to the Internet and the data they generate is easily available. 

Privacy advocates are concerned about the "big brother is watching you" aspects of pervasive computing, but from a practical standpoint, most researchers feel it will improve efficiency.  In a 1996 speech, Rick Belluzo, who was then executive VP and general manager of Hewlett-Packard, compared pervasive computing to electricity. He described it as being "the stage when we take computing for granted. We only notice its absence, rather than its presence."
An example of a practical application of pervasive computing is the replacement of old electric meters with smart meters. In the past, electric meters had to be manually read by a company representative. Smart meters report usage in real-time over the Internet.  They will also notify the power company when there is an outage, reset thermostats according to the  homeowner's directives, send messages to display units in the home and regulate the water heater."

Even these days in our daily life we can catch a glimpse of ubiquitous computing. With the ubiquity and cheap cost of mobile computing devices with different features and sensors. It is beginning to emerge, start assisting us in our daily lives. It is  predicted that in future this kind of 'ubiquitous computing' devices will become so pervasive, invisible and non-obstructive that we will rely on them to assist us on performing our daily routines, or automating our tasks.

Hello, world !!!

Hello, Everyone . This is my first blogpost here. I'm creating this blog to share latest IT, hi-tech, software and other interesting news that I have found in internet, also I needed some place to gather my ideas and other data of my own :P . I guess it will be fun !!!
