Local area networks provide services for their users. Often the services are replicated for throughput, reliability, or physical convenience. Access for these services can be provided in a number of different ways that differ in such details as where the queues reside, how explicitly each user needs to specify the service, and the consequences of local failures.

A network connects multiple computers and printers. Each printer is driven by one of the computers, provides service to the entire network, and is equipped with multiple paper trays. A program running on any computer may specify any paper tray on any printer for its print requests.
