Embedded Systems vs IoT – Key Differences.pdf

In today’s fast-paced technological world, Embedded Systems and the Internet of Things (IoT) stand out as two transformative paradigms redefining how devices interact with their surroundings. As our lives become more interconnected, these technologies play a critical role in shaping the way we live, work, and engage with the environment around us.

This article explores the core distinctions between IoT and Embedded Systems, unraveling their unique architectures, functionalities, and practical applications in the modern era.
