Textbook's Chapter 13 is dedicated to embedded computing and in particular embedded OS. It overviews the general properties of embedded OS, and esp. in what regards those have to be different from the OS's of standard laptop/desktop/mainframe computers. It also surveys a few prominent examples of embedded oper. systems, such as Tiny OS, micro-CLinux, etc. Going beyond those examples, and thinking about various mission-critical cyber-physical and/or cyber-secure systems, would be some key features of OS's for such systems, that would differentiate them from both the 'traditional' operating systems (such as Windows 10, Red Hat Linux, etc.) and even the given examples of embedded OS's discussed in the slide deck for the Chapter? Discuss some such features you can think of, or that you can find outside of Stallings and the lecture notes
