Difference between IoT and Big Data

Both the Internet of Things (IoT) and Big Data are currently the trending topics that are frequently discussed in the context of the information technology industry. It is practically impossible to discuss one of these topics without also bringing up the other. Both are the wave of the future when it comes to data, and by data, we mean enormous amounts of data. We are now living in a digital age in which new things are constantly being linked to the Internet in an effort to make people's lives easier.

Read through this article to get an overview of IoT and Big Data and how these two technologies are different from each other.

What is IoT?

The phrase "Internet of Things" refers to the collective network of linked objects and the technology that permits communication between these devices and the cloud. Due to the development of low-cost computer processors and high-bandwidth telecommunications, there are currently billions of gadgets that are linked to the Internet. This means that sensors could be used in everyday items like toothbrushes, vacuum cleaners, vehicles, and machinery to collect data and respond intelligently to what their owners do.

Parts of an IoT System

A standard IoT system accomplishes its goals by collecting and exchanging data in real time. There are three parts to an IoT system −

Graphical User Interface

A GUI may be used for the management of an Internet of Things device or fleet of devices. A smartphone application or website that can be used to register and operate smart devices is a common example. Other examples include the following.

Smart Devices

A smart device refers to a piece of hardware that has computer capabilities and may take the form of a television, a security camera, or even workout equipment. It does this by gathering information from its surroundings, user inputs, or use patterns and then communicating this information to and from its IoT application through the Internet.

IoT Application

An Internet of Things application is a collection of different services and pieces of software that work together to integrate the data that is gathered from different IoT devices.

In order to evaluate this data and arrive at well-informed conclusions, it employs a technique known as artificial intelligence (AI) or machine learning. These choices are then sent back to the Internet-of-Things device, which responds smartly to what it gets.

What is Big Data?

"Big Data" refers to very large and ever-increasing quantities of data that company collects but is unable to examine using more conventional approaches.

Big data, which encompasses both structured and unstructured data types, is often the raw material that businesses use to perform analytics on in order to extract insights that might assist them in developing more effective business strategies.

Big Data is more than just an unintended consequence of the processes and uses of technology. One of the most valuable resources in today's world is large amounts of data.

The 5 V's of Big Data

The 5 V's highlight the most important characteristic features of Big Data −


The amount of the data will serve as the wide base of the pyramid that represents big data. Around the year 2012, organisations all over the world started amassing more than three million new pieces of data on a daily basis, which marked the beginning of a meteoric rise in the amount of data that businesses everywhere handle.

Based on what an MBA professor at Antonio de Nebrija University has found, the volume is thought to have doubled about every 40 months since then.


The pace at which new data is created is referred to as its "velocity," and it is measured in bits per second.

It is not just the quantity of big data that may be valuable; the rate at which it is generated, often known as its velocity, is an essential factor. When it comes to gaining a competitive edge, for businesses who want to get important and actionable insights from it, having it be as near as possible to real time is optimal.


"Variety" refers to the many ways big data may be presented and the many sources a company can use. This includes mobile phones, home gadgets, social media, stock ticker data, and financial data. The source's importance must match the company being studied. For example, a retailer must consider social media input on a new apparel line. A manufacturer wouldn't benefit from monitoring social media.


A lack of veracity casts doubt on the reliability and precision of the data. Data that has been thoroughly cleaned is the most reliable. In order for businesses to be able to trust their data, they need to connect, clean, and convert it across all of their systems. For them to maintain control over their data, hierarchies and numerous data links are necessary.


The highest point of the pyramid is where you can get the most value, which is when you can take actionable business insights from a flood of data.

Businesses that are able to make money off of the insights that may be gleaned from large amounts of data are valuable. They continue to make services that are more useful while also learning more about their customers.

Differences between IoT and Big Data

The following table highlights the major differences between IoT and Big Data −

Parameters of Comparison
Big Data
IoT is an idea whose core tenet is to create a network of interconnected computing devices so that intelligent machines may replace the need for human mediators.
The idea of "big data" is to compile all of the most recent information, whether it be statistics, news, or content that might assist in making decisions.
IoT Collect and Process Data Generated by Machines, which is then Aggregated and Compressed by Sensors Such as a Steam Iron.
Big Data processes data that was created by humans, such as emails, posts on social networking platforms, and other information that users contribute.
Real time
In order to arrive to useful conclusions, The Internet of Things makes use of data that is collected, processed, and analysed in real time.
The processing of large amounts of data does not occur in real time. The gathering of data comes first, followed by the analysis of it after some time has passed.
The Internet of Things’ primary objective is to identify and resolve problems that may be present in assets.
With the help of Big Data analysis, we may get to the bottom of an issue by delving into the mountains of data that are already collected.
In the context of IoT, having the ability to comprehend the data collected by machine sensors is essential for producing accurate results.
Big Data Analytics is a method that derives conclusions from enormous amounts of data by using statistical frameworks.


IoT and Big Data may be complementary to one another, but they each have distinct responsibilities to carry out in relation to data over the Internet. When both of these terms come together, it often leaves people confused and leads them to believe that they perform the same function, however, this is not the case at all.
