pool

A pool, in computing, is a reservoir of resources such as threads, memory, or database connections that are kept ready for use. Instead of creating and destroying these resources each time they're needed, the pool allows quick access, improving efficiency and performance. For example, a connection pool manages a set of database connections that applications can reuse, reducing delay and conserving resources. This concept helps systems handle multiple tasks smoothly by managing resources efficiently, ensuring faster response times and better scalability without unnecessary overhead.
