如今，物联网(通常简称为IoT)和大数据已成为信息技术界日常使用的热门术语。不提另一个就很难谈论一个。尽管它们之间有着密切的联系，但它们之间却没有相互联系。两者都是数据的未来，就数据而言，我们指的是海量数据。我们生活在一个数字时代，其中新物体已连接到Internet，旨在改善人们的生活。
物联网，物联网或者，是指能够收集互联网连接的设备或机器和交换数据的全球网络。简而言之，IoT就是收集数据并将其发送到Internet的设备。物联网是一个巨大的异构集合，它们彼此不同。物联网旨在整合和收集信息，并为不同领域中使用的各种物理事物提供服务。
每天，数十亿个字节和数万亿字节的数据是由连接到Internet的数十亿个设备生成的，以至于过去几年中，全球90％的数据已生成。大量的数据来自各种来源。从社交媒体网站上的帖子，数字图片和视频，交易记录，付款历史记录，用于收集气候信息的传感器或GPS信号，仅举几例。这些数据统称为Big Data 。使用传统的软件技术几乎不可能分析和处理如此大量的结构化和非结构化数据。
让我们看看物联网和大数据之间的区别。
| SR.NO. | IOT | BIG DATA |
|---|---|---|
| 1 | IoT is a global system of interrelated computing devices that are able to sense, collect, and exchange data over the Internet. | Big Data is described as large sets of data generated from a variety of sources that are so large to process using traditional techniques. |
| 2 | The concept is to provide interconnection between devices to create a smart environment thereby making machines smart enough to bypass human intermediaries. | The concept is to find insights in new and emerging types of data and content that lead to better decisions and strategic business moves. |
| 3 | IoT collects, analyzes, and processes data streams in real-time without any delay to make control decisions in an effective manner. | The data streams are not subjected to processing real-time and there is a delay between when the data is collected and when it is processed. |
| 4 | IoT involves analyzing machine-generated data such as sensors in home appliances and so on. | Big Data deals with human-generated data such as social media usage, photos, and videos, etc |
| 5 | IoT is about simultaneously collecting and processing data to make real-time decisions. | Big data is more into collecting and accumulating huge data for analysis afterward. |
| 6 | Using IoT you can track and monitor assets like trucks, engines, HVAC systems, and pumps. You can correct problems as you detect them. | With big data, you can analyze all the information you have about failures and start to uncover the root causes. |
