Minneshanteringsmetoder, also known as memory management techniques, are strategies and algorithms used by computer systems to allocate and deallocate memory space for programs and data. The primary goal is to efficiently utilize the available memory, prevent conflicts, and ensure the smooth operation of applications.

One common method is static memory allocation, where memory is assigned to variables or data structures at compile time. This approach is fast and predictable but lacks flexibility, as the memory size must be known beforehand. Dynamic memory allocation, on the other hand, assigns memory at runtime. This allows for flexible usage, as memory can be requested and released as needed. However, it introduces the risk of memory leaks if allocated memory is not properly freed.

Garbage collection is a technique often employed in dynamic memory management. A garbage collector automatically identifies and reclaims memory that is no longer in use by the program. This helps prevent memory leaks and simplifies memory management for developers. Alternatively, manual memory management requires the programmer to explicitly allocate and deallocate memory. While offering greater control and potentially higher performance, it is more prone to errors.

Paging and segmentation are techniques used in operating systems to manage virtual memory. Paging divides memory into fixed-size blocks called pages, while segmentation divides memory into variable-size logical segments. These methods allow programs to use more memory than is physically available by swapping data between RAM and secondary storage. Effective memory management is crucial for system performance, stability, and the prevention of crashes.
