The internet of things, or IoT, is a network of devices that connect and exchange data with each other and the cloud. It’s a network of physical objects, devices, vehicles, buildings, and other items that are embedded with sensors, software, and network connectivity. These “things” are capable of collecting and exchanging data over the internet, enabling them to interact with each other and with humans. 

IoT relies on technology that links the physical and digital worlds. Objects get sensors to keep an eye on things like temperature or movement, and they can respond to changes through actuators. These sensors and actuators talk to computers through wired or wireless connections. And they aren’t limited to man-made things; nature, people, and animals can be part of IoT too.

It involves countless devices worldwide that connect to the internet, gathering and sharing data. Thanks to tiny, affordable computer chips and widespread wireless networks, almost anything, from a tiny pill to a massive airplane, can join the IoT. By adding sensors and connecting these objects, they become smart and can communicate data without human involvement. This makes our world smarter and more responsive, bridging the gap between the digital and physical realms.

With IoT, data moves over networks without people having to do everything. Think about a smart thermostat at home or a fitness tracker you use to stay healthy. These are part of IoT, which has become a big part of our lives and how businesses work. Businesses are using IoT to work better, serve customers, make smarter decisions, and grow.

The beauty of IoT is that it’s always connected, combined with data and analysis, opening up new opportunities for businesses to create better products, services, and run more efficiently. 

IoT has a wide range of applications and benefits, such as improving efficiency, automation, and convenience in various industries. For example, it can help optimize energy consumption in smart homes, enhance predictive maintenance in manufacturing, enable precision agriculture, and enhance healthcare monitoring.

IoT has been one of the most significant trends in business and technology in recent years.

How Does IoT Work?

To understand how IoT works, you have to know its key components. The key components of IoT include:

1. Things or Devices: These are the physical objects or devices that have been enhanced with sensors, processors, actuators, and network connectivity. Examples include smart thermostats, wearable fitness trackers, Wi-Fi integrated appliances, industrial machinery, and even smart cities infrastructure.

2. Connectivity: IoT devices are connected to the internet or other communication networks, allowing them to transmit and receive data. This can be done through various means, including Wi-Fi, cellular networks, Bluetooth, and low-power, long-range networks designed specifically for IoT (e.g., LoRaWAN).

3. Data Processing: IoT devices collect data from their surroundings using sensors (e.g., temperature, humidity, motion, GPS) and process this data to extract meaningful information. Some devices can perform basic data processing locally, while others rely on cloud-based servers for more complex analysis.

4. Cloud Services: The data collected by IoT devices is often sent to cloud-based services for storage, analysis, and processing. These services can provide a centralized platform for managing and monitoring multiple devices and can host applications that enable data analysis, visualization, and control.

Before the data is shared, it is also sent to an edge device where that data is locally analyzed to reduce the volume of data sent to the cloud, minimizing bandwidth consumption. 

The way these devices communicate with other related devices and the internet and how they act on the gathered information depends on the job they’re doing. There’s no one-size-fits-all, so they use different ways to stay connected.

What Makes IoT Possible?

History of IoT

The concept of having a network of smart devices was introduced way back in 1982 when computer scientists at Carnegie Mellon University hooked up a Coca-Cola vending machine to the ARPANET. This clever machine could tell people if it had cold drinks and how many were left.

IoT grew from machine-to-machine (M2M) communication, where machines connected to each other without human interaction. M2M connects devices to the cloud, manages them, and collects data. IoT takes it to the next level with billions of smart devices, linking people, systems, and applications to share data. M2M offered the connectivity that enables IoT.

It’s also an evolution of supervisory control and data acquisition (SCADA), which controls processes and collects real-time data. SCADA systems, which included hardware and software components, gathered data and feeds it to a desktop computer with SCADA software, and then is processed and presented in a timely manner. Late generation SCADA systems were integrated into first-generation IoTs. 

Fast forward to the ’90s, and experts like Mark Weiser were pioneering concepts like “ubiquitous computing” in 1991. In 1994, an article in IEEE Spectrum described the concept of moving small packets of data to loads of devices, making everything from home gadgets to entire factories smarter.

Companies like Microsoft and Novell were throwing around ideas in the mid-’90s, but it was Bill Joy who really kicked things into gear with his “Six Webs” concept in 1999, which includes device-to-device communication.

The term “Internet of things” got its start in a 1985 speech by Peter T. Lewis, but it didn’t really take off until 1999 when Kevin Ashton used the term during a presentation to Procter & Gamble. He liked to call it the “Internet for things” and saw RFID as a key part of it. In 1999, MIT professor Neil Gershenfeld also gave us a glimpse of the IoT future with his book “When Things Start to Think.”

By 2004, smart folks were already predicting that IoT devices would take over. Cornelius “Pete” Peterson, CEO of NetSilicon, predicted that they’d become even more popular than regular computers, and that medical devices and industrial controls would become its dominant applications.

Cisco Systems says the IoT was born between 2008 and 2009 when the number of connected things surpassed the number of people. 

From 2010 to 2019, IoT became a part of our daily lives. Smartphones, smart TVs, and other connected devices started connecting to one other.

By 2020, IoT devices were everywhere, using various networks like 2G, 3G, 4G, 5G, LoRaWAN, and LTE-M. In 2023, billions of IoT devices gather and share data for consumers and industries. IoT plays a big role in creating digital twins, virtual copies of real-world things, and healthcare has embraced it with wearables and remote monitoring.


The Internet of Things (IoT) has transformed the way we live and work, creating a connected world where everyday objects communicate and collaborate to enhance our lives. As we’ve seen, IoT’s roots stretch back to early concepts in the ’80s and ’90s, with pioneers like Kevin Ashton and Bill Joy setting the stage. It has thrived thanks to technological advancements, from low-cost sensors and robust connectivity to the power of cloud computing and machine learning. 

IoT has ushered in a new era that enabled us to monitor our health, optimize our homes, and improve industries from manufacturing to healthcare. It’s not just a technological revolution – it’s a lifestyle revolution, and it’s here to stay.
