IoT enabled Big Data. The Internet of Things (IoT) consists of all the web-enabled devices  that collect, send and act on data they acquire from their surrounding environments using embedded sensors, processors and communication hardware. These "connected" or "smart" devices, can sometimes talk to other related devices and act on the information they get from one another.

Thanks to cheap processors and wireless networks, it's possible to turn anything, from a pill to an aeroplane, into part of the IoT. This adds a level of digital intelligence to devices that would be otherwise dumb, enabling them to communicate without a human being involved, and merging the digital and physical worlds.

To illustrate the benefits of blockchain and Internet of Things convergence, IBM gives the example of complex trade lanes and logistics whereby smart contracts can follow (and via blockchain technology register), everything that has happened to individual items and packages. The benefits: audit trails, accountability, new forms of contracts and speed, to name a few.

Technology, whereby mainly security comes in the picture. In an Internet of Things context where security is already a challenge, it’s clear that security needs to be even more looked at. It is important to note though that blockchain is also seen as a way to secure the Internet of Things and, as mentioned, security overall but that is another discussions with several opinions and aspects to cover.

Fog computing, a form of edge computing and also propagated by Cisco shifts analysis of IoT data to the point of origination, thus speeding up things and freeing up bandwidth and other resources in non-distributed analytics (at the edge, in the network and in some form of cloud integration).

While the Internet of Things today mainly is approached from the perspective of connected devices, their sensing capabilities, communication possibilities and, in the end, the device-generated data which are analyzed and leveraged to steer processes and power numerous potential IoT use cases, the Internet of Everything concept wants to offer a broader view.

What is the Internet of Things? According to TechTarget’s WhatIs.com, the Internet of Things is “a scenario in which objects, animals or people are provided with unique identifiers and the ability to transfer data over a network without requiring human-to-human or human-to-computer interaction.” And the “things” part of this is basically anything that can be given an IP address and the ability top transfer data over a network.

Although we're beginning to see more and more connected devices, remember that on the whole, IoT is still very immature. This can create disruptive opportunities for early adopters. But it's also causing many companies to wait to see what happens before they jump into IoT.

Considered a subset of the Internet of Things (IoT), WoT focuses on software standards and frameworks such as REST, HTTP and URIs to create applications and services that combine and interact with a variety of network devices.

Like pervasive computing, IoT-connected devices communicate and provide notifications about usage. The vision of pervasive computing is computing power widely dispersed throughout daily life in everyday objects. The internet of things is on its way to providing this vision and turning common objects into connected devices, yet, as of now, requires a great deal of configuration and human interaction.

An example of pervasive computing is an Apple Watch informing a user of a phone call and allowing him to complete the call through the watch. Or, when a registered user for Amazon's streaming music service asks her Echo device to play a song, and the song is played without any other user intervention.

Ubiquitous computing is a concept in software engineering and computer science where computing is made to appear anytime and everywhere. In contrast to desktop computing, ubiquitous computing can occur using any device, in any location, and in any format. A user interacts with the computer, which can exist in many different forms, including laptop computers, tablets and terminals in everyday objects such as a refrigerator or a pair of glasses.

Neelam,

Privacy is easily the most often-cited criticism of ubiquitous computing (ubicomp), and may be the greatest barrier to its long-term success.

Video is widely considered the eye of IoT. It is a game changer. Vision technology is helping companies use video and images to better understand their business in transportation, public services, retail, industrial manufacturing, healthcare and more.

In a nutshell, the Internet of Things refers to devices other than computers that are connected to the Internet and can send and receive data. The term has been around for more than 15 years, though it only began gaining wide currency more recently.
