20- True or False? What is the difference between physical and logical
concurrency?
(a)Physical concurrency is several program units from the same program that

(b)Logical concurrency is multiple processors providing actual concurrency, when
in fact the actual execution of programs is taking place in interleaved fashion on a
single processor.
