What is the difference between IoT and embedded systems?
The rapid advancement of technology has led to a merging of boundaries between different sectors. This convergence is particularly noticeable in the realm of IoT (Internet of Things) embedded systems, where the terms "IoT" and "embedded system" are often used interchangeably. However, it's important to recognize that embedded systems and IoT are distinct concepts, even though they share some similarities.
Embedded systems have been in existence since as early as 1965 when Autonetics, a company, created a small computer for use in a missile guidance system. These embedded systems are essentially standalone devices designed with a specific, dedicated function in mind. On the other hand, an IoT embedded system is an embedded system that possesses the added capability of connecting to the internet, enabling communication with other IoT embedded systems.
In our daily lives, we are surrounded by IoT embedded systems, including devices such as set-top boxes, Point-of-Sale (POS) terminals, various medical devices, "smart" appliances like refrigerators, bicycles, fitness trackers, and even parking meters.
In the following discussion, we will delve into the intricacies of embedded systems designed for IoT devices. We will explore what defines an embedded system for IoT, its capabilities, and practical applications of embedding IoT functionality into these systems.
The key distinction between IoT (Internet of Things) and embedded systems boils down to one crucial factor: connectivity. Even an embedded system, like a pacemaker, can be transformed into an IoT embedded system when it gains the ability to communicate with the external world, such as sending heart-rate data to a central database.
Another distinguishing feature is that IoT encompasses a broader category of devices representing the interconnected world, whereas an embedded system pertains specifically to the hardware within these devices.
The fundamental difference between an embedded operating system and an IoT operating system lies in the necessity for IoT systems to support connectivity. The capability of IoT devices to network and communicate sets apart plain embedded systems from their IoT counterparts.
In every IoT scenario, there's an embedded system at its core, which is why the term "IoT embedded system" is used. Initially, there exists an embedded system, and then additional features are integrated to transform it into an IoT device.
Embedded systems can be remarkably sophisticated, such as robotic systems used in manufacturing or data warehouses. However, their function as pure embedded systems remains limited to their specific purpose until they acquire the ability to communicate and establish connectivity with other IoT embedded systems.
Therefore, the primary distinction between an embedded system and an IoT embedded system hinges on the latter's capacity for communication and connectivity.
