What is the Internet of Things?
The Internet of Things, or IoT, refers to the billions of physical devices around the world that are now connected to the internet, all collecting and sharing data. IOT is an intelligent technique which reduces human effort as well as easily accesses physical devices.
In other we can say IoT devices are basically smart devices which have support for internet connectivity and are able to interact with the other devices over the internet and grant remote access to a user for managing the device as per their need.
The term “Internet of Things” was coined by an entrepreneur Kevin Ashton, one of the founders at Auto-ID center at MIT. Ashton was first to use the term Internet Of things but the concept of connected devices has been around for long time.For example, machines have been communicating with each other since the first electric telegraph was developed in late 1830s by Samuel Morse.
Other technologies that fed on IoT were radio voice transmission and wireless (WIFI) technologies and now a days these have extended to Bluetooth Mesh Networking, Lifi, Near Field communication and many more.
2.1.IMPACT OF IOT ON OUR WORKING PRACTICES
Here are some examples how the Internet of Things (IOT) has changed our lifestyles:
- Patients can keep a record of their health using remote administration of medication.
- The Internet of Things also gathers all the data it can from you and lets each fixture and appliance in your smart house adjust themselves according to your established routine and personal preferences.
Raspberry Pi is used to implement IOT. It supports Python, C, C++, Java and many more programming languages. It is a ‘Single Board Computer’ which is widely used all over the world.
Eben Upton, a British engineer is the creator of the Raspberry Pi and the Raspberry pi Foundation.
He realized that young individuals or students turned away from computer professions, so he had a goal of creating a rather smaller and cheaper device, he came with a solution- Raspberry Pi.
it made a sale of more than 5 million by February 2015, making it the best-selling British computer.
RASPBERRY PI VERSIONS
The Raspberry Pi Foundation Provides Raspbian, a Debian-based Linux distribution as well as third party RISC OS. Ubuntu, Windows 10 IOT Core and other specialized media center distributions. OS (Linux-based):
- Lubuntu, Xubuntu, Gentoo Linux
- Arch Linux ARM, Devuan
- SUSE Linux Enterprise
- CentOS, RedSleeve
- Ark OS, Kali Linux
- OS (not Linux-based0).
- NetBSD, Haiku.
- HelenOS, OpenBSD.
- Plan 9 from Bell Labs.
- Windows 10 IoT Core.
4.FUTURE IS IOT
We are living in this technologically advanced world, and everything here is moving toward automation. From smart doorbell to smart package tracking system, everything is becoming smart and taking all of us towards a new era. all because of IoT. Following are the areas where IoT has become reality and is doing brilliant job: –
- Smart Home: This include using the IoT devices to implement the concept of home automation, for tasks like lighting, air conditioning, etc.
- They have voice control which can help the people & also include specials sensors which sends alert if any medical emergency is there.
- Health Care.
- Smart Transportation.
- Smart parking, Automatic toll collector, Fleet manager, smart traffic manager etc. are some other areas where IoT is used.
- Wearable devices/fitness trackers. (e.g., Jawbone Up, Fitbit, Pebble)
5.CHALLENGES IN IOT
As IoT brings the new and amazing opportunities to ease our lives, it also brings the new security concerns.
We are giving the system so much of data each and every minute since it is monitoring, detecting and tracking the things around us.
IoT connects a large number of devices together via internet and this makes is vulnerable as hackers can attack the system.
Hacker can steal the data, may make it unusable or make the whole system vulnerable to cybercriminals.
Additionally, connected devices often ask users to input their personal information, including names, ages, addresses, phone numbers and even social media accounts — information that’s invaluable to hackers.
Hackers are not the only threat to the IOT and its users; privacy is also a concern for IoT users.
For instance, companies that make and distribute consumer IoT devices could use those devices to obtain and sell user’s’ personal data. Not only leaking the personal data.
but IoT poses a risk to different type of services and resources which use IOT and may also risk human life.
So, it is necessary that we take complete measures to keep all the points in mind while working with IOT to efficiently and securely use it.
