1. What is Concurrency?
Junior
A.the property of a system that deals with many tasks making progress over overlapping time periods, which may or may not run literally at the same instant
B.an independent program instance with its own isolated memory address space and resources managed by the operating system
C.the smallest unit of execution scheduled by the OS that runs within a process and shares that process's memory with its siblings
D.the act of the scheduler saving one execution stream's state and restoring another's so a single core can be shared among many tasks
2. Which term means: "the property of a system that deals with many tasks making progress over overlapping time periods, which may or may not run literally at the same instant"?
A.Concurrency — the simultaneous physical execution of multiple computations, typically on separate CPU cores at the very same instant
B.Concurrency — a single sequential flow of control through a program with its own stack and program counter
