Memory Pool

Definitions

1. A pre-allocated block of memory divided into fixed-size chunks that can be quickly allocated and deallocated without calling the system allocator. Eliminates fragmentation and allocation overhead for objects with predictable sizes. Common in game engines, network servers, and embedded systems.

   In plain English: Pre-reserving a chunk of memory and carving it up yourself, faster than asking the operating system each time.

   Example: "The game engine uses a memory pool for particle objects — allocating 10,000 particles per frame can't afford malloc overhead."
