As its name suggests, Embedded means something that is attached to another thing. An embedded system can be thought of as a computer hardware system having software embedded in it. An embedded system can be an independent system or it can be a part of a large system. An embedded system is a microcontroller or microprocessor-based system which is designed to perform a specific task. For example, a fire alarm is an embedded system; it will sense only smoke
The purpose of embedded systems is to control a specific function within a device. They are usually designed to only perform this function repeatedly, but more developed embedded systems can control entire operating systems.
There are many benefits to using embedded systems. For example, they are highly customizable and low cost, which makes it easy and affordable to tailor them to exact functional and performance requirements. They also have low power consumption, which helps reduce energy costs for the overall system.
