Introduction
Unbeknownst to us, embedded systems are much more common than we believe. But what are they actually, and where are they used? This article compares desktop and laptop PCs to embedded systems, weighs their benefits and drawbacks, and examines some use cases and examples.

What is embedded system?
An embedded system, as opposed to, say, a laptop, is made specifically for one particular machine or device, is dedicated to that machine or device, and is used to control the operation of that machine or device. The embedded system, as its name suggests, is typically embedded within the “device or machine,” which can be anything from a smartwatch to a sizable medical imaging system or robot.
The embedded system’s ability to monitor sensor inputs—such as those for temperature, voltage, or video—perform control and possibly analytical calculations on the measured data, and then set outputs to actuators like displays, lights, motors, or valves accordingly, is necessary for its control function. As a result, the embedded system needs a set of input ports that are physically and electrically compatible with the sensors it is monitoring. They ought to be accurate and precise enough, with the appropriate range and scale. Additionally, electrical interference resistance should be incorporated. Along with electrical isolation between the power and control circuits, outputs with enough power to drive the actuators are also required.
Advantages of embedded system
Because they are focused on a single application, they can be more affordable. For instance, high-performance graphics might not be included, and some systems might not even have a graphical user interface. If the desired application does not require high-performance computing, other systems may have processors with lower performance and power demands. Such technologies would also require little power; some might even function with batteries. In addition to being exceedingly small and simple to locate, embedded systems can also be ventilated without needing a lot of surrounding space.

Applications of Embedded Systems
As previously indicated, embedded systems can be found in applications of all sizes, starting with smartwatches. Other minor illustrations include:
- GPS devices
- electronic cameras
- gaming systems
- cellular routers
- photocopiers
In this respect, smartphones are interesting gadgets. They display many embedded system traits, but they can also execute user-specified software, making them similar to desktop PCs in that regard.
Programmable logic controllers (PLCs), which are frequently used in industry, could be justified in a similar way. They are frequently built on an industrial PC architecture, so while they have embedded system features like a robust design and an RTOS, they also have a desktop PC-type capacity to accept various applications—at least at the time when they are sent from their original manufacturer.
