A message queue is a commonly used mechanism for communication between a server and a mainframe computer. Messages are placed into a queue on one system and retrieved from the queue by the other system, allowing for asynchronous communication between the two. Swimlanes and synchronization bars are not typically used in this context, and an EBCDIC conversion unit would be used for converting character sets between ASCII and EBCDIC, but not for communication between systems.
