Briefly describe the main functions of storage management.

The addressing space operating system makes the system appear to have more memory space than the actual memory. Virtual memory can be many times the actual physical space in the system. Each process runs in its own virtual address space. These virtual spaces are completely isolated from each other, so the processes will not affect each other.

Storage management system is divided into internal memory and external memory, both of which are used to store data. Memory is the temporary storage of data, with fast access speed. After power failure, memory will release space, so data will disappear. External storage (also called hard disk) is the long-term storage of data. As long as the data is not deleted after power failure, the data will still exist.

The storage management subsystem is one of the most important components in the operating system, and its purpose is to facilitate users' use and improve the utilization rate of memory.

Memory allocation and recycling, memory allocation and recycling, storage protection, virtual storage. According to relevant public information, it is found that: memory allocation and recovery.

Storage management mainly focuses on the operation and maintenance of storage management. This process is used to define, track and maintain data and data resources in the production IT environment.

Storage management mainly refers to the management of memory, the purpose is to improve the efficiency of memory use as much as possible. The object of memory management is main memory, also called memory. Its main functions include allocating and reclaiming main memory space, improving the utilization rate of main memory, expanding main memory and effectively protecting main memory information.
