1. Different operating system structures offer both benefits and drawbacks over one another, and it’s important to understand what kind of structure should be used for different use-cases. Consider the following situation. You are tasked with creating a very secure piece of software for an embedded system that should have a relatively small amount of overhead. Given the nature of embedded systems, once you deploy the system you won’t be able to update the software, thus maintainability isn’t a large factor. What structure (simple, layered, microkernel, or modular) should you choose for its kernel? Explain.
