System a has two processors. program x takes 50 seconds to execute on one of the processors. program y takes 50 seconds to execute in parallel on the other processor. system b has a single processor that can execute only one program at a time. program x takes 35 seconds to execute on this processor. program y takes 35 seconds to execute on this processor. which system would you pick if you cared about overall system throughput for a workload that is a mix of programs x and y?

I will pick system A

Explanation:

System A has dual processor and it will concurrently run the two program(X and Y) in 50 seconds, with program X on the first processor and program Y on the second one while system B will take 70 seconds to run the two program since it runs on a single processor, it will run program X first and then program Y next, summing up to 70 seconds. so therefore I will pick system A since I'm  considering the system throughput.

when the first user logs into windows 10 or windows server and identifies their region, windows sets the time zone. the user can change the time zone at any time.

windows updates the time zones in the registry when time zones are available and updates are downloaded.

to get the most current list of time zones, use tzutil from windows:
