IOT - INTERNET OF THINGS

Hey I know-I know that this Article is too long but its neccesary so

coming to the agenda of the session we started by checking out a quick introduction to IOT and will understand dwhy we require IOT after that we'll take a quick overview on how IOT works and the architecture of it as well and lastly we'll check out the applications and the usage of the Internet of Things.

Last but not the least will checkout my final thoughts on the session to start out with let me ask you this did you know that by the time you pretty much read everything when you screen right now by the time you saw the tiny animation there are 4,000 new devices which connected to the Internet just now so all in total there are 50 billion devices that are connected to the Internet worldwide.

Today and in the internet rush era everyone wants to get into the Internet today right so be it or you know attaining new information be it into using your internet as a market place or as an entertainment place you know so if you want any new information you're reading something you want to learn something master you new IT skills .

For example you will come to the Internet and then if you want to sell something if you want to become an e retailer or anything like that you will come to the Internet as well and then if you're looking for some entertainment beet Netflix or any other music source TV watching source or whatever it is you will come to the Internet so you realize that we can actually validate why 50 billion devices across the world are actually connected to the Internet today.

I know that not if these many devices are connected to the Internet how best can one make use of it and this brings us to the quick introduction to IOT when we talk about IOT the first thing we need to discuss is what is IOT .

IOT is basically "an interconnected web of objects and these objects in our case are called as things hence Internet of Things".

So basically these things the objects that we talk about are guided with sensors they have software present they have a lot of hardware and all of these combine together to achieve one single purpose to achieve one single goal so there are multiple goals of IOT and we'll be covering in the next part of the session as well so whenever you think of Internet of Things whenever you think of anything IOT the first thing that might come into your mind is all the hardware and the software which works in coordination to make it work so why do we require IOT in today's world.

we have 50 billion devices connected to the web so or in today's world we need to and that with these many devices connected there is a lot of data being generated right so there's zetta bytes there's petabytes and whatever is the new term for 10 power x where you know X can be 15-20 so open this much amount of data has being generated every day we understand that by using data science.

Various Aspects Of IOT

We can make use of these data to drive our capability better to take nicer decisions to take decisions which will help in the short term and the long term as well so with respect to a IOT .

we have more data and now we can club it Club it and with the right software and hardware to make better decisions so the next thing is smart healthcare with respect to IOT when we talk about smart healthcare it's all about your well-being to the best where you can use the latest bit of hardware and software which is available to you to probably let your doctors know to let your physicians know about your current health conditions current well-being and what not even if they are not physically present with you.

all you need to do is have these devices at hand and ensure that you have an active internet connection and you will have the access to the entire world of smart healthcare and the next thing is convenience and automation so with respect to IOT you can change all the mundane tasks done by humans and basically make everything smart and convenient for the people.

This does is this ensures that your work force your population will basically put in their time and efforts to the tasks that are more productive that are more qualitative and at the end of the day which drive more insights to your business and of course if you have smart wearable technology if you're building smart cities if you have a smart home and everything smart at the end of the day it increases the quality of your life totally right so you can open your door by sitting at your office by the click of a button on your phone for example if you have guests at home so most of the time it so happens that we are at work to work and there's a delivery package at our home and 90% of the time either we leave it with our neighbors or we ask for the next day delivery well with the use of IOT you can actually ensure that you know you can have a small separate box which opens at your command .

IOT In Home Based Mobile Application

The end of the day you can have these parcels and packets sent into that box and then you can later lock it remotelyhttps://en.m.wikipedia.org/wiki/Near-field_communication and what not well the one thing you need to know about IOT is that the absolute endless hunt for making things smart everything from smartwatches as I just mentioned to smart shoes to basically anything you can think of so it can be a smart health tracker whatever it is if it is associated with the word smart there is a 70% probability that it includes something to do with the Internet of Technology .

Now coming to IOT as a carrier well these are among the 4 most important reasons of why you should consider IOT to be your carrier :

It is among the top 10 jobs in the entirety of this decade it was in the top 10 jobs for the last decade and it has been projected it's gonna remain in a higher spot at this decade as well now coming to business requirements in today's world everyone wants their problems to be solved at the quickest with respect to IOT there is this demand and supply created where the demand is high while supply is less.
if you jump on the IOT trend you can make a very good carrier out of it and of course we live in the mobile era right so for 80% of our tasks during the entirety of the day we look at our Mobile's for its speed browsing the Internet beat ordering food beat our getting into a meeting .We are the mobile era so we are a generation of mobile users who are basically achieving goals and feats which could have not been done probably 10 years before now anyway 20 years ago this would have just been fiction right .
It's is that IOT is a one-stop solution to everything be it be it recycling be green energy beat your health monitoring be it smart cycles be it your working environment being smart beat power saving whatever it is so we can go on and name unlimited number of applications on why IOT should be a very good career path for you guys and of course at the end of the day it is an amazing career path.
then when we have to talk about how IOT actually works well IOT works on a five main principle components are one it's the hardware hardware consists of all of these sensors the actuators and everything which form the actual device is this the part of the sensing layer which means check out in the architecture and then comes the software then you have to talk about software you will be writing custom code and custom programming concepts.

You'll be helping this hardware talk to the internet and of course if you have to make a software talk to the internet you actually need access to the Internet and this is where there's the protocol layer where you'll be actually making your software and hardware connected to each other.

We are in the internet era and then when you think about it when you're on the internet you need some security so defining security protocols to ensure that your software's your hardware and in fact the entirety of your IOT device is safe the security protocols are very much important and then of course after all of this is done your device is ready now you need a way to control this to control all of this you can make use of your computer you can make use of your mobile and at the end of the day anything that's connected to the Internet can have access to this.

Here is where you have your application here is where you'd have your dashboard here is where basically you will have the controlling entity to go on make changes used or IOT device and everything else so if you have to talk about the IOT stack the first thing that we need to talk about is when we say Internet of Things the thing is basically the goal objects so this thing is the entity is the asset .

Vivid Info

It can be the device which we want to monitor as well so to do this we understand the 1 step is to have a thing so after we get the thing that we want to control and monitor we need to provide it with some data so in the data acquisition stage.

We ensure that we get a signal and we make the software talk to the hardware by converting the software from an analog s format which is basically the result of the input and the outputs of the hardware and convert all of this into a digital format after the data has been converted into a digital format and read by the software well to combine and use this software with data present present everywhere you need to have access to data processing methodologies with respect to data processing methodologies you have data analytics data processing techniques and of course if you have analyzed the data .

If you have processed data you need a place to store it there comes data storage and of course at the end of it you need a communication module where your device scan either communicate on a local network or they can communicate via a cloud network or any other third party network communication systems as well so the stack begins by having a goal thing then we have the data acquisition .

Local Area Network

Cloud Network

After acquiring the data we perform data processing and after data processing we have the communication module where your IOT device can talk to a network stack all in all and of course if you're talking about IOT wise management we have four important things we need to cover there's notifications security updates data reports and our data updates as well with respect to notifications every time there is a change in your IOT device.

Every time there is a change in the network or the behavior of your device the user or the person who's programming it must have a notification and of course security updates are something very important because your devices will be connected to a network when it's connected to a network and especially to the internet or people with malign intent are present everywhere to make sure that your device does not succumb to this we need to provide our security updates as well and of course data reports are a process of either debugging your IOT devices or ensuring that it is a goal.

For example if you are wearing a Smart Watch indicating the data reports is the goal how much what is the number of kilometers that you've run what does the GPS position of you when you were running what was the inclination or probably what was your heartbeat and much more right so these data reports can be the goals in most of the cases which is very important and then we have the general data updates where every second your Iove device has to have an interval where it keeps shuffling through the data.

It keeps generating new information based on this data let's consider the run example again let's say we running around a track and now do you want the data to be collected every single second do you want the data to be collected and analyzed every 10 seconds 20 seconds right so you get the picture this is where you set an interval of data updates where these updates are taken in by a IOT devices processing is done .

Crucial Approachs

The data is pushed to the dashboard as well so how does data communicate when you talk about IOT the data movement in any IOT devices is basically based on these 6 concepts :

Wi-Fi.
Bluetooth.
cellular mobile.
Internet.
RFID (who is basically the radio frequency identification).
NFC (which is Near Field Communication).

RFID

NFC

The radio frequency tower communications as well so basically these 6 are different protocols all and all together where some are near-field communication devices and some are far-field where they do have a particular range.

For example Wi-Fi will have a greater range than Bluetooth and you will get a cellular connection in most of the places today because there are cell towers everywhere there are RF towers and with NFC .
