DIFFERENCE BETWEEN IOT & EMBEDDED SYSTEMS
0 likes73 views
Embedded systems are specialized computing systems designed for specific tasks within larger systems, often operating independently without internet connectivity. In contrast, the Internet of Things (IoT) involves a network of interconnected devices that require internet connectivity to collect and exchange data, enabling smart functionalities. While embedded systems focus on functionality and real-time performance, IoT emphasizes connectivity and data-driven applications.
DIFFERENCE BETWEEN IOT & EMBEDDED SYSTEMS
- 2. www.piestsystems.com Embedded Systems An embedded system is a specialized computing system designed to perform a specific task within a larger system. It typically involves a combination of hardware (microcontroller or microprocessor) and software that operates in real-time with limited resources. Embedded systems are commonly found in devices like home appliances, cars, industrial machines, and medical devices. IoT (Internet of Things) IoT refers to a network of interconnected devices that collect, exchange, and act on data through the internet. These devices can range from simple sensors to complex embedded systems. IoT emphasizes connectivity, enabling communication between devices (or "things") and remote systems (cloud servers, applications) to enable smart functionalities.
- 3. www.piestsystems.com Connectivity Embedded Systems : Embedded systems do not necessarily require internet connectivity. They are often standalone systems designed to operate independently, though they may interact with other devices via local communication (e.g., CAN, SPI, I2C, UART). IoT : IoT devices, by definition, must have some form of internet connectivity, whether via Wi-Fi, cellular networks, or other communication protocols. The central feature of IoT is its ability to send and receive data over a network.
- 4. www.piestsystems.com Purpose Embedded Systems : Embedded systems are typically designed for specific, fixed functions. They focus on control, monitoring, and data processing within the device they are embedded in. IoT : IoT extends the capabilities of embedded systems by connecting them to the internet. IoT devices aim to provide insights through data collection and enable automation, remote control, and monitoring of systems.

- 6. www.piestsystems.com Software and Protocols Embedded Systems : Embedded systems often use low-level programming languages (e.g., C, assembly) and are built to run with limited resources (e.g., memory, power). They may use real-time operating systems (RTOS) for time- sensitive operations. IoT : IoT devices often utilize both embedded software and higher-level communication protocols (e.g., MQTT, CoAP) to enable cloud integration and data analytics. They may involve more complex software stacks due to the need for network communication, security, and scalability.
- 7. www.piestsystems.com Focus Embedded Systems : Focus on functionality, real-time performance, and resource efficiency. IoT : Focus on connectivity, data-driven applications, and integration with the internet/cloud.
