The difference is that being written in high-level languages Java, C++, or Python, embedded software is more sophisticated and performs high-level functions such as data processing and interaction with other devices. While firmware can handle tasks without operating systems, embedded software requires a special OS.

Do embedded systems have operating system?
An embedded operating system is an operating system for embedded computer systems. This type of operating system is typically designed to be resource-efficient and reliable. … Unlike a desktop operating system, the embedded operating system does not load and execute applications.
Is OS must for embedded systems?
Do you need an OS at all? For many embedded applications, it is obvious that an OS is needed. If the application is complex and is running on a high-end processor, it is almost certain that an OS would be beneficial. At the other end of the scale, simple software running on a low-end chip has no need of an OS at all.
Why would you want an OS for an embedded system?
The purpose of an embedded operating system is: to insure the embedded system operates in an efficient and reliable manner by managing hardware and software resources. to provide an abstraction layer to simplify the process of developing higher layers of software. to act as a partitioning tool.

What are non embedded systems?
The device drivers in non-embedded operating systems run directly on the hardware and do not get associated with any operating system. When the system contains the operating system, what will the device driver be like? Firstly, a non-embedded operating system’s device-driven hardware’s operation may still be essential.
