Os Memory Management Questions
Static memory allocation refers to the allocation of memory at compile-time or before the program execution begins. The memory size is fixed and determined in advance, and it remains constant throughout the program's execution. Static memory allocation is typically used for global variables and data structures that have a fixed size.
On the other hand, dynamic memory allocation refers to the allocation of memory at runtime or during the program's execution. The memory size can vary and is determined based on the program's needs. Dynamic memory allocation is typically used for creating data structures such as arrays, linked lists, and objects, where the size may change during program execution.
In summary, the main difference between static and dynamic memory allocation is that static allocation occurs before program execution and has a fixed size, while dynamic allocation occurs during program execution and allows for variable memory sizes.
