Description: The reallocation table is a fundamental data structure in memory management of operating systems. Its main function is to keep track of memory allocations and their changes over time. This includes information about which memory blocks are occupied, which are free, and how they have been reassigned to different processes. The table allows the operating system to efficiently manage memory, ensuring that processes have access to the memory they need without conflicts. Additionally, it facilitates the identification of memory leaks and the optimization of resource usage. Reallocation tables can vary in complexity, from simple structures that only record the state of memory blocks to more advanced systems that include information about the size of the blocks and their physical location in memory. In summary, the reallocation table is crucial for the stability and efficiency of the operating system, as it allows precise control over available memory and its allocation to running processes.
