Match the pairs in the following questions by writing the corresponding letters only.
Buddy system - The buddy memory allocation technique is a memory allocation algorithm that divides memory into partitions to try to satisfy a memory request as suitably as possible. This system makes use of splitting memory into halves to try to give a best fit.
Interpretation - Run-time (pretty obvious)
Pointer type - Garbage collector dereference the dangling pointers
Virtual memory - Segmentation
In object-oriented languages with garbage collection, dangling references are prevented by only destroying objects that are unreachable, meaning they do not have any incoming pointers; this is ensured either by tracing or reference counting.
