MemoryAllocator

MemoryAllocator is a fundamental component in computer programming responsible for managing the allocation and deallocation of memory. When a program needs to store data, it requests a block of memory from the operating system. The MemoryAllocator acts as an intermediary, keeping track of which parts of memory are in use and which are free. It provides functions to request a specific amount of memory (allocation) and to return that memory back to the system when it's no longer needed (deallocation).

There are various strategies and algorithms employed by MemoryAllocators to optimize performance and memory usage. Common techniques include first-fit, best-fit, and worst-fit algorithms, which determine how free memory blocks are selected for allocation. Memory fragmentation, where small, unusable gaps of free memory appear between allocated blocks, is a significant challenge that allocators aim to minimize. Garbage collection is another related concept, often implemented in higher-level languages, where unused memory is automatically detected and reclaimed. Efficient memory management is crucial for the stability and performance of software, preventing issues like memory leaks and crashes.
