Memory management schemes in operating system
WebWhat is Memory management in Operating System. Memory management is a function of the OS. It helps us with: handling the movement of processes between main memory and disk during execution. keeping track of every memory location, whether allocated or free. checking the amount of memory to be allocated to a process. WebThis lab project addresses the various memory-management schemes in an operating system. We model the memory managed in an operating system as a list of memory blocks. Each block of memory is modeled by a data structure of MEMORY_BLOCK defined below: struct MEMORY_BLOCK { int start_address; int end_address; int segment_size;
