buddy system

The buddy system is a resource management technique often used in computing and memory allocation. It works by splitting memory into blocks of sizes that are powers of two, helping optimize storage and reduce fragmentation. When a request is made for a certain amount of memory, the system finds a suitably sized block. If the block is larger than needed, it divides it into two smaller "buddies." This method ensures efficient use of memory while making it easier to allocate and deallocate spaces as needed. It’s particularly beneficial in environments with fluctuating memory demands.
