Memory Management

Memory management is a crucial aspect of computer systems, involving the allocation and management of memory resources for programs. It ensures that computer memory, which is a finite resource, is used efficiently. Memory allocation can occur either before a program runs (static memory allocation) or during its execution (dynamic memory allocation).

In static memory allocation, the compiler assigns a fixed amount of memory at compile time, and this memory cannot be changed during runtime. The operating system uses a stack data structure to manage this memory. Conversely, dynamic memory allocation allows for memory management at runtime, utilizing functions like malloc(), calloc(), realloc(), and free() in C programming. This method uses the heap space of the system memory, enabling more flexible memory usage as program requirements change.

Understanding memory management is essential for software developers, as it directly impacts application performance and resource utilization ¹²⁴.
