The Listener is a protocol-independent application listener that receives connections on behalf of applications running over a variety of underlying protocols. The Listener is a component of SQL*Net, Oracle's remote data access product, enabling client/server and server/server communications across any network. It runs as a single process or task.

For more information about the Listener, see the manual Understanding SQL*Net.

remember youngster....google is your friend.

Listener is like the receptionist at an organization. The receptionist directs any incoming call to the person requested for. She knows/has access to all the extension numbers and knows who sits where in the building. Whenever someone (user) calls she asks for the person name (database name) to whom the caller wants to talk (connect), and then connects the caller (create a server process) to the person, then waits for other calls.

If you know how a receptionist works you know how a listener works :)

Does it log only connect/receive entries or logs connection disconnect/expire/exit also?

just connects.
