Introduction to Operating Systems
Operating systems are an essential component of any computer system, including real-time and embedded systems. They act as a bridge between the hardware and software components of a system, managing resources such as memory, CPU, and input/output devices. The key benefit of an operating system is that it provides an abstraction layer for the hardware, making it easier for software developers to write applications that can run on different types of hardware.
Real-time and embedded systems have specific requirements that make them different from traditional desktop or server systems. For example, a real-time system must be able to respond to events within a specific amount of time, whereas an embedded system must be designed to operate in a limited environment with constrained resources. Operating systems play a crucial role in ensuring that these requirements are met and that the system runs smoothly.
