Abstract
A distributed data processing system is provided that is particularly well-suited for enabling a plurality of single-tasking computers connected to a network to continuously process input from the network and each computer's respective peripherals. A polling routine, resident on each computer, periodically polls the peripherals (including a network adapter) which are connected to the computer. Layered communications software is also resident on each computer and enables each computer to send and receive data to and from the network. The polling routine and layered software call predetermined application procedures in response to input from the peripherals and the network.
