Abstract:

This report describes the Basic Operating System BOS for the Distributed Computer Network DCN. The BOS is a multiprogramming executive providing process and storage management, interprocess communications, inputoutput device control and application-program support. It operates with any PDP11 model including at least 4K of storage, an operators console and a communication device for connection to the DCN. Included in this report is a description of the various components that make up the BOS and the manner in which they operate. Also described are the various primitive functions and command operations used to control the operation of the network and the various application programs. Other reports, listed in the references, describe the functioning of the DCN as a whole and also the upwardly-compatible Virtual operating System VOS developed for PDP11 models with memory management features.
