Let’s use the term “PC” to refer to the standard laptop and personal computer we use generally, without considering the Operating System(OS). For the purpose of this question lets consider an Apple Mac as a PC and assume that the “real time systems” and “embedded systems” means the same.

Define a real-time embedded system according to your understanding?

1. Provide three examples of real-time embedded systems. (Just mention the examples, explanation is not required)
2. Managing processes is one of the essential task of an OS. An OS controls the CPU time by managing different processes. Describe how an OS for a conventional PC vary from the OS of real time embedded system in terms of process management.
3. An OS also controls memory. Describe how an OS for a conventional PC vary from the OS of real time embedded system in terms of memory management.
4. An OS directs input and output. Describe how an OS for a conventional PC vary from the OS of real time embedded system in terms of Input-output management.
