Memory management refers to the technology of allocating and using computer memory resources when software is running.

Memory management is very important for writing efficient Windows programs. This is because Windows is a multi-tasking system, and its memory management is very different from that of single-tasking DOS.

DOS is a single-task operating system. After an application allocates memory, if it does not actively release it, the system will not make any changes to it; but this is not the case with Windows. It may have multiple tasks at the same time. Applications share memory. Sometimes in order to perform a certain task better, the Windows system may move or even delete the memory allocated by other tasks.

Therefore, when we use memory in Windows applications, we must follow some conventions of Windows memory management to maximize the utilization of Windows memory.
