What type of listener does the server typically use when waiting for a connection request?

A server typically uses a passive listener when waiting for connection requests. This type of listener is designed to listen on a specific port for incoming client connections without actively initiating the connection itself. Instead, it remains in a standby mode, ready to accept a connection when a client attempts to connect.

In contrast to active listeners, which may try to initiate connections to other services or clients, a passive listener waits for external requests. This is a key concept in network communication models where a server needs to handle multiple incoming requests and manage them efficiently. By using a passive listener, the server can maintain its resources and respond only when a request is made, which is fundamental to how most server-client architectures operate.

Understanding the role of a passive listener provides insight into the design of network protocols and the implementation of server applications, emphasizing the importance of managing both connection requests and system resources effectively.
