What Is IoT?

The Internet of Things (IoT) is a system of interrelated computing devices, mechanical and digital machines, and the ability to transfer data over a network without requiring human-to-human or human-to-computer interaction. The IoT allows you to automate and control the tasks that are done daily.

How Does It Work?

The Internet of Things is an added layer of data, interface, transaction, and action which is added to the Internet. It can be your portable devices, electrical appliances, security systems, automobiles, smart devices, and sensors.

Future Business of IoT:

The future of the IoT industry is getting larger day by day. The business insider revealed that almost 24 billion IoT devices are set to be installed by the year 2020. In 2019, IoT revenue has reached 357,000,000,000 while bringing several employment opportunities in the field of Information technology (IT).

Major Components of IoT:

Cloud computing convenience:

IoT cloud offers tools to collect, process, manage, and store huge amounts of data in real-time. Cloud is a sophisticated high-performance network of servers optimized to perform high-speed data processing of billions of devices, traffic management, and deliver accurate analytic.

Software designed networking:

SDN is an approach to networking that enables network nodes to be managed through programming, rather than traditional system administration methods. SDN needed when networks grow too big for manual configuration


smart sensors are used to extract data from the environment and transmit the information to the next layer. Smart devices and sensors can be connected to low power wireless networks like Wi-Fi, Bluetooth, etc. An object can be a simple sensor that measures the atmosphere temperature; the weight etc. common sensors are Temperature sensors and bimetallic strip, pressure sensors. It must be able to connect to the network and send the measured data.

Challenges of IoT:


The sensors can be connected to the cloud through various mediums of communication and transports such as cellular networks, satellite networks, Wi-Fi, Bluetooth, wide-area networks (WAN), low power wide area network and many more.

IoT Gateway:

  • A gateway is an object that connects several devices to the cloud.
  • These devices can be placed in different areas and instead of connecting directly to the cloud they use a gateway to connect to it.
  • A gateway can provide protocol translation feature, for example, a gateway connects to the devices using a low power protocol

Security and Privacy

Security: Lack of security increases the risk of your information leaking while the data is collected and transmitted to the IoT device. IoT security is the technology zone concerned with protection-connected devices and network in the internet of things (IoT)

Privacy: Internet of Things privacy is the superior considerations compulsory to protect the data of individuals from exposure in the IoT environment.

  • Authentication, Identification, and device heterogeneity are major security and privacy concerns in IoT.
  • There are a lot of Security and Privacy Issues with the Internet of Things devices, including increased risk of cyber and ransomware attacks.

User Interface:

User interfaces are the visible, tangible part of the IoT system which can be accessed by users. The user interface design has higher significance in today’s competitive market, it often determines the user whether to choose a particular device or appliance.

IoT Protocol: There are several IoT protocols available. Even if we can use protocols like HTTP, there are others much more effective and appropriate in the IoT ecosystem.

Data Processing: Once the data is collected and it gets to the cloud, the software performs processing on the acquired data.

IoT Smart House:

Smart Home is the term commonly used to define a residence that has appliances, lighting, heating, air conditioning, TVs, computers, entertainment audio & video systems, security and camera systems capable of communicating with one another and can be controlled remotely by a schedule, from any room in the home, as well as remotely from any location in the world by phone or internet.

Intelligent Buildings:

a smart building is one that is using technology to share information about what goes on in the building between systems to optimize the building’s performance. Intelligent Buildings Institute defines an intelligent building as “one which provides a productive and cost-effective environment.
