Question
Chapter 3, Problem 41CRP
Program Plan Intro
Starvation:
When more than one process executes in overlapped time period and one of the processes do not get time for its execution to complete, then that particular process suffers from starvation.
Deadlock:
In a computer system, a process utilizes resources to execute its instructions. In a condition when the two processes simultaneously acquire resources of the other process, the processes are not able to execute their instruction and this condition is called deadlock.

Question10:
The following is not a property of transactions: (a) Permanent: once committed, the results of a transaction are made permanent. (b) Serializable: the result of concurrent transactions must be the same as if they were run in serial order. (c) Indivisible: the transaction appears as an indivisible action. (d) Bounded: a transaction must have an upper bound on the time it takes to complete

- 112. Four necessary conditions for deadlock to exist are: mutual exclusion, no-preemption, circular wait and a. hold and wait b. deadlock avoidance c. race around condition d. buffer overflowarrow_forwardProblem Statement: (The following problem is based on problem statements in a number of operating systems texts) For this lab, you'll be setting up 2 queues of PCBs. A process control block (PCB) is an internal structure that is used to hold information associated with a process. A process is an instance of a program that is brought into random-access memory (RAM) for execution. To simplify matters, you'll be setting up 2 queues: a ready queue and a wait queue and, PCBs each PCB will have 2 fields: a process ID or PID (a positive integer) a link field to point to the next PCB on a queue The ready queue will have the PCBs for the processes that will be run in a first-come, first-served fashion. The wait queue will have the PCBs for the processes that will be waiting for a resource in a first-come, first-served fashion. If the PCB at the head of the ready queue needs some resource (for example, I/O) then it will be removed from the ready queue and moved to the rear of…arrow_forwardPlease refer to this textbook: “A.

- All deadlocks are caused by competing demands for resources.arrow_forwardAs a result, when individuals speak about dynamic memory allocation, what precisely do they mean? What's the goal of it all? Many of the most important functions in the C programming language make it feasible to allocate memory in a dynamic manner. Please answer with code examples that are suitable for the situation.arrow_forwardDynamic Versus Stack Allocated Memory Describe by example and words the difference between dynamic and stack allocated memory, specifically arrays. How they are created and destroyed, and describe their scope. Are there any limitations with either memory types? Lastly, has modern C++ provided any new features (hint: standard template library data types) to alleviate problems associated with dynamic and/or stack allocated memory?arrow_forward
