The Internet of Things (IoT) refers to devices  that are connected to a wireless network. In other words, a system of interrelated computing systems, mechanical and digital machine that are provided with unique identifiers (UIDs) and the ability to transfer data over a network (Internet) without requiring human-to-human or human-to-computer interaction.

Internet of Things = “Sensors and actuators embedded in physical objects are linked through wired or wireless networks, often using the same Internet Protocol (IP) that connects the Internet.


By Tech Target definition “A unique identifier (UID) is a numeric or alphanumeric string that is associated with a single entity within a given system. UIDs make it possible to address that entity, so that it can be accessed and interacted with.” This sounds very logical to everyone who had a chance to use UIDs or to listen to someone who knew how to describe and explain true nature, usage and need for UIDs. 

History of IOT

Kevin Ashton, co-founder of the Auto-ID Center at MIT, first mentioned the internet of things in a presentation he made to Procter & Gamble (P&G) in 1999. Wanting to bring radio frequency ID (RFID) to the attention of P&G’s senior management, Ashton called his presentation “Internet of Things” to incorporate the cool new trend of 1999: the internet. MIT professor Neil Gershenfeld’s book, When Things Start to Think, also appearing in 1999, didn’t use the exact term but provided a clear vision of where IoT was headed.

Imapct in our daily life

IoT-based smart cities use data and technology to create a more efficient and sustainable infrastructure to manage the resources, traffic flow, population behavior, develop the local economy, and improve the quality of life of residents. Done right, smart cities will be able to deliver many benefits including:

  • Reducing traffic congestion; for example, routing cars away from an area where a major traffic accident has just occurred.
  • An ambulance can go through the streets sounding an alarm which stops all other traffic by changing the traffic lights. Additionally, a nearby connected hospital will be standing by to expect the arrival of the patient.
  • Smart parking can reduce a great deal of driving time and fuel while searching for a parking space during busy times.
  • Smart city lighting will reduce energy consumption when no one is present.
  • Smart buildings can be stand-alone projects or part of a smart city, in which energy can be monitored during peak usage hours to minimize brown outs.
  • Early warning systems can be installed in a smart city so when major accidents, earthquakes, or storms occur, the nearby first responders, police and hospitals can be informed all at the same time.

History & Facts

1. Automated teller machines (ATMs) represented the first generation of IoT products when they started coming online in 1974.

2. By 2008, there were already more internet-connected devices then there were human beings on the planet.

3. General Electric has used IoT concepts for years to improve its jet engine technology. Complex sensors stationed around each airplane can generate up to 14 gigabytes of data per flight. Engineers can use this data to make improvements to the plane’s engines and other systems.

4. Developed over a decade ago, the railroad industry uses a sophisticated system of software and RFID tags to track railcars and their contents.

5. One of the first internet-connected appliances was a Coke machine at Carnegie Mellon University. Sensors allowed students to see if the machine was stocked and whether drinks were cold.
