What Is Embedded System?

An embedded system is a computer system and a combination of hardware and software. It includes mechanical and electric parts and electronic devices. So, an embedded system can’t be made up of a single machine, it is a combination of multiple machines to perform a particular task.

The heart of embedded systems is integrated circuits because they are responsible for computation and real-time operations. Embedded system is different from general-purpose computers because they perform diversified tasks while embedded systems perform dedicated functions.

Moreover, an embedded system is not always a computer device with integrated software. However, most embedded devices are based on microcontrollers and microprocessors. An embedded system doesn’t need to have a keyboard and screen. An embedded system can work individually and can be a part of large system hardware to complete tasks of the physical world.
