The queued components service enables you to create components that can EXECUTE asynchronously or in disconnected MODE. 

Queued components ensure availability of a SYSTEM even when one or more sub-systems are temporarily unavailable. 

Consider a scenario where SALESPEOPLE take their laptop computers to the field and enter orders on the go. 

Because they are in disconnected mode, these orders can be queued up in a MESSAGE queue. When salespeople connect back to the network, the orders can be retrieved from the message queue and processed by the order processing components on the server.
