What is IOT? | Understanding The Internet of Things

The internet of things, to use intelligently connected devices and systems to leverage data gathered by embedded sensors and actuators in the machines and other physical objects. IOT is expected to spread rapidly over the coming years and this will improve the quality of our connected life.

Physical and virtual things in an IOT have their own identities and attributes and are capable of using intelligent interfaces and being integrated as an information network. In easy terms, IOT can be described in connected devices that are uniquely identifiable. 


The Internet of things has been identified as one of the emerging technologies in IT.

ARCHITECTURE OF IOT:-

A critical requirement of an IOT is that the things in the network must be connected to each other. IOT system architecture must guarantee the operations of IOT, which connects the physical and the virtual worlds.

APPLICATION LAYER:

  • Lowest abstract layer
  • with sensors, we are creating digital nervous systems
  • incorporated to measure physical quantities.

GATEWAY AND THE NETWORK LAYER:

  • Robust and high performances network infrastructures
  • allows multiple organizations
  • support and communications requirements

MANAGEMENT LAYER:

  • Capturing of periodic sensory data
  • Ensure security and privacy data

INTERNET OF THINGS ELEMENTS:

There are three IOT components that enable seamlessly:

  • Hardware: It is made up of sensors, actuators, and embedded communication hardware.
  • Middleware: On-demand storage and computing tools for data analytics.
  • Presentation: Novel easy to understand visualization and interpretation tools that can be widely accessed on different platforms.

CLOUD CENTRIC INTERNET OF THINGS:

The vision of IOT can be seen from two perspectives- ‘internet ‘centric and ‘thing’ centric. The internet-centric architecture will involve internet services being the main focus while data is contributed by the objects. In object-centric architecture, the smart object takes the center stage.

The new IOT applications specific framework should be able to provide support for:

1) Reading data streams either from sensors directly or fetching the data from the database.

2) Easy expression of data analytics logic as functions/operations that person data streams in a transparent and scalable manner and cloud infrastructures.

3) If any events of interest are detected, outcomes should be passed to output streams.

SERVICES/ BENEFITS OF IOT:

  • Improved citizen’s quality of life
  • Healthcare from anywhere
  • Better safety, security, and productivity
  • new business opportunities
  • IOT can be used in every vertical for improving the efficiency 
  • creates new business and new and better jobs
  • economic growth
  • Better environment 
  • saves natural resources and trees
  • helps in creating a smart, greener, and sustainable planet
  • Improved competitiveness
  • competitive in providing cutting edge products/services

QUANTUM STORAGE & MEMORY

  Quantum computers stand to transform the world of computers. They have the capacity to be greatly more powerful than our current digital devices, with the power to solve important computational problems and simulate complex physical systems with unmatched efficiency. Like memories are an important component for computers, that’s like quantum memories are also essential components for quantum computers, a new generation of data processors that follow the laws of quantum mechanics and these laws help to overcome the limitations of classical computers. Quantum computers are expected to be much faster and more powerful than their traditional analogue as information is calculated in qubits (the fundamental unit of computation in quantum computing)  in quantum computers while the older units are bits which used in classical computers, can represent both 0 and 1 at the same time. Quantum memory is used as a key element in information processing, such as optical  quantum computing  and  qu

Biofuel generation with the help of Bioinformatics

Due to the continuously growing natality rate, increased availability of healthcare and food production has led to decreased mortality and further proliferated, population outburst on earth. This has caused strain on the energy sources and thereafter there has been an endless search for the most convenient, fast, and long-lasting method of renewable source of energy. According to the sources, from 2011 to 2021, renewable energy has grown from 20% to 28% of the global electricity supply. Fossil energy shrank from 68% to 62%, and nuclear from 12% to 10%. The share of hydropower decreased from 16% to 15% while power from sun and wind increased from 2% to 10%. Biomass and geothermal energy grew from 2% to 3% . Among many energy sources, Biomass can be one of the most trusted renewable energy sources, due to its abundance of availability present in nature. Biomass refers to organic material from plants or animals. This includes wood, sewage, and ethanol (which comes from corn or other plant

PHISHING ATTACKS IN INDIA

-
What do mean by phishing ?  Phishing is a type of online fraud when con artists pretend to be reputable companies or organizations in order to deceive victims into giving up personal information like passwords or credit card details. Phishing efforts can take the shape of emails, websites, or even text messages, and can appear authentic at first glance. A phishing attempt can be identified in a number of ways, including misspellings, odd syntax, and sudden requests for personal information. Do not respond to the message if you believe you are being targeted by a phisher; instead, report the incident to the relevant authorities. Phishing in India !!!! India is a vast and developing country. Digitalization is being done at a speedy rate. This brings a lot of ease for the general public but also creates a pool of opportunities for scammers, hackers, and con men. As per an article by Times of India Between April 1, 2020, and March 31, 2022, clients lost roughly 1500 crores in these scams.
