Internet of Things - number of connected devices worldwide 2015-2025

By 2025, forecasts suggest that there will be more than 75 billion Internet of Things (IoT) connected devices in use. This would be a nearly threefold increase from the IoT installed base in 2019. What is the Internet of Things? The IoT refers to a network of devices that are connected to the internet and can “communicate” with each other. Such devices include daily tech gadgets such as the smartphones and the wearables, smart home devices such as smart meters, as well as industrial devices like smart machines. These smart connected devices are able to gather, share, and analyze information and create actions accordingly. By 2023, global spending on IoT will reach 1.1 trillion U.S. dollars. How does Internet of Things work? IoT devices make use of sensors and processors to collect and analyze data acquired from their environments. The data collected from the sensors will be shared by being sent to a gateway or to other IoT devices. It will then be either sent to and analyzed in the cloud or analyzed locally. By 2025, the data volume created by IoT connections is projected to reach a massive total of 79.4 zettabytes. Privacy and security concerns  Given the amount of data generated by IoT devices, it is no wonder that data privacy and security are among the major concerns with regard to IoT adoption. Once devices are connected to the Internet, they become vulnerable to possible security breaches in the form of hacking, phishing, etc. Frequent data leaks from social media raise earnest concerns about information security standards in today’s world; were the IoT to become the next new reality, serious efforts to create strict security stands need to be prioritized.

至2025年，据预测，将会有超过750亿台物联网（IoT）设备投入使用。这一数量将是2019年物联网安装基础的近三倍。何谓物联网？物联网是指连接至互联网并能够相互“通信”的设备网络。此类设备包括日常科技小玩意，如智能手机和可穿戴设备，智能家居设备，如智能电表，以及工业设备，如智能机器。这些智能连接设备能够收集、共享和分析信息，并据此采取相应行动。至2023年，全球对物联网的支出预计将达到1.1万亿美元。物联网是如何运作的？物联网设备利用传感器和处理器收集并分析从其环境中获取的数据。传感器收集的数据将通过发送至网关或其他物联网设备进行共享。随后，这些数据将被发送至云端进行分析，或进行本地分析。至2025年，物联网连接产生的数据量预计将达到惊人的79.4泽字节。隐私和安全问题鉴于物联网设备生成的大量数据，数据隐私和安全问题自然成为物联网采用的主要关注点。一旦设备连接至互联网，它们便可能成为黑客攻击、网络钓鱼等安全漏洞的受害者。社交媒体频繁的数据泄露引发了对当今世界信息安全标准的深切担忧；若物联网成为下一个新的现实，优先创建严格的安保标准将是一项严肃的努力。
