$1.$ You have a choice of running Windows Server or Linux for an application. Explain the factors you should consider when deciding which one to choose.

$2.$ Applications designed that require Rosetta on MacOS are not running optimally. Explain.

$3.$ One of the factors that can affect CPU performance is its clock speed. Explain in detail what this represents. What are common speeds on current desktop processors?

$4.$ Why are there so many different Linux distributions? List the top $3$ and why each one is popular and made the top $3.$

$5.$ It is well understood that SSD hard drives are faster than older magnetic hard drives. Find a comparison between two actual drives $($one SSD and the other magnetic$)$ that supports this with performance metrics.

$6.$ What are the primary roles of an operating system? Point form is fine.

$7.$ You notice that on your computer there are many more threads than processes. Why is this?

$8.$ What is RAM used for?

$9.$ Windows is associated with the Intel x$64$ architecture, but it seems this may be about to change. Briefly explain the history of Windows on ARM and why it may become more popular.

$10.$ Why is single$-$core CPU performance still important when virtually all CPUs today are multi$-$core?

$11.$ Apple$$s iOS and Google$$s Android are smartphone operating systems. Explain how these differ from a desktop or server OS$.$

$12.$ What is the difference between user mode and kernel mode of an OS$?$ Give an example of a process that runs in each.

$13.$ How can you run a $64-$bit application on a $32-$bit OS$?$

$14.$ You have been asked to determine the specifications for a $($physical$)$ server that will run MySQL database. This database server will serve a mid$-$sized company that will run a number of databases for standard business$-$type applications. Their databases $($roughly $20)$ consume about $1\mathrm{.}5$ TB of disk storage space in total. You can make reasonable assumptions for usage$/$load$.$ Provide a list of minimum specifications for CPU, memory, and disk. Provide some explanations$/$justifications$.$ Match your specifications to an actual server model being sold by a popular server vendor $($HP$,$ Dell, Cisco, Lenovo, etc.$)$
