- Memory Management Indirect relative addressing refers to an addressing scheme in which the memory address to be accessed is specified explicitly. The memory management unit (MMU) maps virtual to physical addresses. Segmentation is a memory management approach in which memory areas (segments) allocated to processes are defined by their starting address (base) and length. The main memory is divided into two partitions when using a single-partition allocation scheme. The frame table used in systems that use paging is a per-process data structure.arrow_forwardHow 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?arrow_forwardMemory Management select which is true options: a The main memory is divided into two partitions when using a single-partition allocation scheme. b The memory management unit (MMU) maps virtual to physical addresses. c The frame table used in systems that use paging is a per-process data structure. d Indirect relative addressing refers to an addressing scheme in which the memory address to be accessed is specified explicitly. e Segmentation is a memory management approach in which memory areas (segments) allocated to processes are defined by their starting address (base) and length.arrow_forward

- In the context of memory allocation, dynamic memory allocation refers to the process by which memory is allocated and deallocated at runtime.arrow_forwardWhat is Dynamic Memory Allocation and how you execute Dynamic memory allocation?arrow_forwardMemory 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 in C language to compare and justify your answer. Noted: Plzz I want this code in C languagearrow_forward
