Brief History of the Industrial Revolution

This section explains the history of the Industrial Revolution.

The First Industrial Revolution

The First Industrial Revolution happened mostly in Britain at the end of the 18th century. It started because of changes in farming, like the enclosure movement, which combined farms and made more workers than needed. This extra labor force was put to work in industries that were growing quickly thanks to new technologies like the steam engine and the automation of cloth production.

During this time, output moved from small shops and homes to factories. The steam engine changed the way people and things were moved, making it easier to get from one place to another. With the help of machines like the spinning wheel and the power loom, the textile industry was changed. This led to more work being done and the growth of cities.

The Second Industrial Revolution

The Second Industrial Revolution happened from the middle of the 19th century to the beginning of the 20th century. It was marked by big scientific advances. During this time, steel production, electricity, and the growth of railroad networks all started. These new ideas took manufacturing to new heights and changed markets all over the world.

Steel was the key to civilization because it made it possible to build bridges, buildings, and railroads. Electricity changed many fields, from industry to transportation to communication. People could talk to each other across long distances once telegraphs and phones were invented. This made it easier for businesses to talk to each other.

The Third Industrial Revolution

The broad use of digital tools in the late 20th century was the start of the Third Industrial Revolution, which is also called the Digital Revolution. This wave brought in computers, the internet, and other information technology systems that changed businesses around the world and paved the way for the digital age we live in now.

Computers and improvements in microelectronics have led to automation, which has increased efficiency and productivity. People, companies, and information from all over the world can now link through the internet. This made it easy to talk to each other, do business online, and share information quickly.

The Industrial Revolution had a huge effect on societies and businesses all over the world. They changed rural societies into urbanized, industrialized countries. People moving from rural places to cities helped cities grow and changed the way people interact with each other. Even though these changes brought a lot of good things, they also brought problems, such as abuse of workers, overcrowding in cities, and damage to the environment.

Industrialization helped the economy grow and made way for capitalism systems. It changed the way things were made, making mass production possible and making items cheaper. The rise of workplaces and the division of labor changed the way people worked, which led to the rise of labor organizations that fought for workers’ rights and better working conditions.

The Industrial Revolution made it possible for technological advances that are still changing our world today. They made it possible for robotics, artificial intelligence, and the Internet of Things (IoT) to grow in the future. We are on the verge of the Fourth Industrial Revolution, which will be driven by the combination of digital, biological, and physical technologies. This will bring more changes and possibilities.

The Industrial Revolutions are important parts of human history because they show how societies went from being based on farming to being based on machines. Each wave brought scientific advances that had never been seen before. These transformations changed markets, societies, and our way of life. By learning about changes in the past, we can learn important lessons about the present and get ready for the challenges and chances of the future.

The Internet of Things

The Internet of Things (IoT) is a technology of interconnected devices, as the name suggests, it is a network of multiple things. In IoT all the things/devices are connected within a network and share the data and information or upload it to the cloud network or internet from where it is easily remotely accessible via smart-phone, laptop or any other device connected to the internet. In the network of connected devices or an IoT network, all the devices have their unique addresses or IPs, which makes it easy for the users to track down the data coming from a specific device or thing.

IoT is not a single technology that is designed over a period, the Internet of Things is a stack of multiple technologies, including hardware and software technologies. It is a combination of both hardware and software that has evolved in the last few decades and is evolving very rapidly nowadays. The fusion of numerous technological developments over the years is where the Internet of Things got its start. The idea originated from the desire to connect and converse with physical objects, allowing them to autonomously gather and share data. Let’s examine the significant turning points in IoT history.

Figure 1.2: Internet of Things

A Brief History of IoT

IoT hasn’t been around for very long. Kevin Ashton came up with the phrase Internet of Things in 1999. He used the phrase as the title of his talk about a new sensor project he was working on, and it stuck after that.

Even though the term connected devices didn’t come into use until 1999, the idea has been around since 1832. When the first electromagnetic telegraph was made, it made it possible for two machines to talk directly to each other by sending and receiving electrical messages. However, the real history of the Internet of Things started when the Internet was created in the late 1960s.

The first IoT gadget was made at Carnegie Mellon University in the early 1980s. A group of university students came up with a way for the Coca-Cola machine on campus to let them know if it was out of Coke through a network. This would save them the trip if the machine was empty. They put microswitches in the machine so that it could tell how many Coke cans were there and if they were cold.

John Romkey was the first person to hook up a toaster to the internet. This was in the year 1990. A year later, a group of the University of Cambridge students reported on coffee using a web camera. They had the idea of using the first web camera device to check how much coffee was in the coffee pot in their computer lab. They did this by setting up the web camera to take a picture of the coffee pot three times a minute. The pictures were then sent to computers in the area so that everyone could check if there was coffee.

Currently, we are living in a time where we first need to collect the data, deploy multiple sensors, get all the information and analyze it. This process needs to be done at a nuclear level to truly understand the functionality of a particular system. Once the data is collected from the environment, it will be easy to integrate multiple machines and devices to control the outcome and hence the process of automation will be achieved.

Pillars of IoT

The IoT is an idea that is changing the way we connect with devices and the world around us. It is a game-changer in a field that is always changing: technology. IoT is the network of physical devices, cars, appliances, and other things that are linked to each other and have sensors, software, and network connections that let them collect and share data.

Since its start, IoT has grown and been used in many industries in a way that has changed how companies work and how people live their daily lives.

IoT’s success can be attributed to its fundamental pillars, which enable seamless integration and communication between devices:
