Abstract : The Berkeley Time-Sharing System is divided into three major parts: The monitor, the executive, and the subsystems. Only the first two of these are discussed in detail in this manual. The manual attempts to describe exhaustively all the features of the monitor and in addition to give a number of implementation details. It also describes those features of the executive which can be invoked by a program. The word monitor is used to refer to that portion of the system which is concerned with scheduling, input-output, interrupt processing, memory allocation and swapping, and the control of active programs. The executive, on the other hand, is concerned with the control of the directory of symbolic file names and backup storage for these files, and various miscellaneous matters. Other parts of the executive handle the command language by which the user controls the system from his teletype, the identification of users and specification of the limits of their access to the system.
