The Distributed Computer Network (DCN) is a resource-sharing computer network which includes a number of DEC PDP11 computers. The DCN supports a number of processes in a multiprogrammed virtual environment. Processes can communicate with each other and interface with this environment in a manner which is independent of their residence within a particular computer. Resources such as processors, devices and storage media can be remotely accessed and shared so as to provide increased reliability, flexibility and system utilization. The DCN now supports several programming languages and applications packages. Programming languages such as SIMPL, LISP, BASIC and others, along with an extensive library of interactive graphics procedures, can be executed in processes which take full advantage of the distributed architecture of the network. Many of the components of the Disk Operating System (DOS) for the PDP11 can be executed in a special emulator-type virtual process now being constructed for this purpose. In this manner the PDP11 assembler, FORTRAN compiler and various system utilities can be supported in the network environment. In cases which exceed the processing power of the network, connections are available to two large Univac 1100-series machines.
