Chapter 4 - The Abstraction: The Process / Processes Process / Job - A running program. The abstraction provided by the OS of a running program. Virtualizing - The process of running a virtual instance of a computer system in a layer abstracted from the actual hardware. Time Sharing (CPU) - By running one process, then stopping it and running another, and so forth, the OS can promote the illusion that many virtual CPUs exist when in fact there is only one physical CPU (or a few). ...

First-Come, First-Served Scheduling correct answers Processes are executed in order received. Convoy Effect - problem where long processes make shorter, potentially more important processes, wait. Shortest Job First Scheduling correct answers Schedule processes/jobs with shortest burst time first. Priority Scheduling correct answers Assign every process a priority Starvation is a risk - low priority processes may never execute. Use aging - increase priority of a process over time...

537 First Half Exam Review A proportional share / fair share scheduler: instead of optimizing for ___________________________, the scheduler might instead try to guarantee that ________________________________________. - ANS-turnaround or response time, each job obtains a certain percentage of CPU time Lottery scheduling is ______________, not _______________________ - ANSprobabilistic, not deterministic High level outline of lottery scheduling? - ANS-- scheduler knows how many total t...

COP4600 Final Combined What pieces of hardware are in the CPU? - ANS Registers, ALU, and control unit Hardware which serves as the CPUs memory. There are special and general purposed of these - ANS Registers Hardware which does arithmetic and logical computations - ANS ALU Hardware which tracks state/status. Also controls other components - ANS Control unit Instruction cycle responsible for loading the instruction - ANS Fetch Instruction cycle responsible for ...
