Internet of Things is the implementation of the interaction between the internet and physical devices and the objects we use regularly such as bulbs, fans and the rest of the things.
To give you an exact idea, the latest example is the Nescafe E Mug.
Who doesn't like their room warmed up before they enter the room? Who doesn't like coffee being prepared while you brush?
These are some of the basic reasons.
Major applications include home automation, infrastructure, manufacturing, health care and security.
To tell in a simple way, it can be related to anything in this World.
What are the disadvantages?
As everything is related to internet connectivity, many professionals find privacy and security being the major concerns.
As we have already learnt about Ethical Hacking, any network is prone to vulnerabilities.
Latest trends in IoT
Amazon Web Services has started its own Internet of Things platform to provide a better place to live. Most of us have heard about Alexa, it enables control over our smart home.
Main components of IoT Systems
- The main part of any system is the collection of data. This is done in IoT using sensors or a device equipped with multiple sensors. A mobile such a device equipped with multiple sensors such as proximity sensor, accelerometer, IR sensor and gyroscope.
- The next step is the transmission of data. This is done using satellite networks, mobile networks, Local Area Networks(LAN) and Wi-Fi. The data is stored in the cloud or any other sources.
- The next step is the processing of data. This processing may range from very simple such as noting the temperature of the room to complex such as identifying trespassers from your cameras.
- Next is displaying data to the user. This may be in the form of triggering alarms in your mobile. For example, if there is a fire in your house, it will trigger an alarm in the fire station.
Companies that are into IoT
There is a huge demand for the applications of IoT. To meet these demands, some of the most widely known companies are trying their best. The companies include IBM, Microsoft, Intel, Google, Cisco and Amazon Web Services.
How to start learning IoT?
As you will be dealing a lot about sensors, you need to have an in-depth knowledge of the sensors used.
You need to have a grip on Arduino and Raspberry Pi.
These things can get you a lot through IoT. Also, don't forget to get into forums and workshops.
Courses available online:
There are many courses available online. Coursera offers a wide range of courses on IoT ranging from basics to the professional level.
