Question Which statement about the memory allocation is incorrect? Releasing memeber through the delete statement means the space occupied by the object is given back to the OS. All kinds of the arrays are allocated in the heap memory hence their size can be large. Automatic memory allocation are mostly introduced for function parameters and local variables; static memory allocation are carried out for the static and global variables. User program is responsible for allocating/releasing the dynamically allocated memory. Dynamic memory is allocated from the heap memory managed and the size is much larger than the stack memory, which are used for normal variables.

Write an efficient parallel program with dynamic task assignment that reads n integers from any input file and finds the 2nd largest (without sorting), using p processors (p << n). Assume m is the largest array size slave computers can handle due to memory limitation (m << n/p) and n is divisible by m. Note: Master has no memory limitation. Please do as follow: Name your file xxxxxH2.c, where xxxxx is at most the first 5 characters of your last name and H2 is the program number. Remember all I/O should be done ONLY by master. Your program should be modular i.e. using subprograms. Make sure to print input data. Print your name at the end of OUTPUT. To execute: mpiexec -n p a.out n m < inputfile Example: mpiexec -n 3 a.out 120 15 < inputfile
A reference parameter differs from an output parameter in that a reference parameter ______________________ but an output parameter does not. a. occupies a unique memory address b. must be a simple data type c. receives a memory address d. requires an initial value
Does dynamic memory allocation work?Can each dynamic memory allocation/allocator be identified and described?
Write a C program which takes four command line arguments: two file names and twonumber of elements. Your program must check if correct number of arguments aresupplied and terminate if not. Your main process must create three processes: The firstand second processes must open / create files by the given names and fill them with thegiven number of random integers (one integer per line) and terminate. The thirdprocess must execute “sort” command with necessary arguments so that it numericallysorts both files and display the combined result on screen.Before creating the third child process, main process must wait for the other two child processes to end.
What describes how the principle of least privlege applies to the use of computers? A, It guarantees that no information inifially held in an object can be used outside its execution environment B, A process is allowed access only to the resources il needs to complete Its task and limit damage from a faulty process C, It is a process that can access an object in a domain only if that domain has a key that malches one of the locks of the object D It is the use of access controls to monitor and limit access to applications, programs, and websites during specific times of use.
How exactly does the process of dynamic memory allocation function when it comes to allocating memory?Is it feasible to recognize and explain the differences between the many types of dynamic memory allocation and allocators?
1. Write a LINUX C code for Banker’s Algorithm to deadlock avoidance.Note: Consider a system with five processes (P0–P4) and three resources (A, B, C). There are 9 instances of resource type A, 4 instances of resource type B, and 6 instances of resource type C
In layman's terms, here's how dynamic memory allocation works.
In the context of memory management, describe in fully the differences between dynamic loading and static loading.
You are required to make changes in the above programs and introduce the use of compaction where required. Write code to simulate Worst-Fit Algorithm TASK2: DESCRIPTION One of the simplest methods for memory allocation is to divide memory into several fixed-sized partitions. Each partition may contain exactly one process. In this multiple-partition method, when a partition is free, a process is selected from the input queue and is loaded into the free partition. When the process terminates, the partition becomes available for another process. The operating system keeps a table indicating which parts of memory are available and which are occupied. Finally, when a process arrives and needs memory, a memory section large enough for this process is provided. When it is time to load or swap a process into main memory, and if there is more than one free block of memory of sufficient size, then the operating system must decide which free block to allocate. Best-fit strategy chooses the block…

Write the C program to solve the question Memory management is the functionality of an operating system which handles or manages primary memory and moves processes back and forth between main memory and disk during execution. Memory management keeps track of each and every memory location, regardless of either it is allocated to some process or it is free. Given five memory partitions of 110 KB, 450 KB, 100 KB, 250 KB, and 500 KB (in order), how would each of the first-fit, best-fit, and worst-fit algorithms place processes of 212 KB, 417 KB, 112 KB, and 426 KB (in order)?Which algorithm makes the most efficient use of memory? Write a program to compare and justify your answer.
