QUESTION 7 What is an advantage of loosely coupled hardware or software? It is more significantly more likely to break under stress due to the weaker connections. You can modify one portion of it without having to make significant changes to the other loosely connected pieces. They are easier to design and most designers naturally fall into this style. O The data streams are quicker and require no additional processing QUESTIONS Which of the following is true of tightly coupled software? O Due to the strong connections between portions of code, it is much more robust and easy to modify individual sections without causing a breakdown O This is a method to prevent spaghetti code because it creates software that is easy to understand for the next maintainers. This is a method of design that separates each function into it's own carefully wrapped module. These tight bundles provide additional support for users. O Untrained programmers often fall into this style automatically, as it is generally quicker and easier to design initially, QUESTIONS What is one method Operating Systems use to make sure each process has a chance to run every second? Hammer O Reactive reboot Timer Anti-redundancy algorithms
