What is the difference between queue and topic?

A connection is created between the client and the server from a connection factory. Connections can be shared by several threads. The user credentials are supplied at this level. It is probably common for a client application to share access to a single connection to the server (unless different security credentials are required for different destinations). A session is created from a connection. The session may only be used by one thread at one time. The user credentials are inherited from the parent connection.
