The study discusses the main basic concepts describing territorially distributed information computer systems that function in a unified information space, and their definitions are given. The defined basic concepts are used in the study of various aspects of the structural and functional construction of such systems. Тerritorially distributed information computer system in a unified information space (TDICS UIS) is defined as a complex territorially-distributed system consisting of a set of organizational structures, software-technical and telecommunication tools, functioning mechanisms, algorithms, technologies, databases and data banks and of knowledge that work in a unified information space and are designed to collect, process, store and provide the necessary information to system users to make timely and adequate decisions. A unified information space is understood as a set of relevant and integral information resources organized according to the single principles and rules of formation, formalization, storage, technology of their management and use, which ensure the possibility of coordinated functioning. of all system elements and is designed to meet the information needs of system users. The creation of a unified information space should provide all users with a single view of the information objects that form the information model of the specified subject area. Various aspects of the construction and functioning of this class of systems have been studied: purpose, main functions, tasks and properties of the system; purpose and properties of a unified information space; information processes occurring in the system; interaction of the system with the external environment; types of security; architecture; main threats and system survivability. It is shown that the very concept of survivability of the TDICS UIS is central to the study of system behavior in abnormal situations caused by negative influences, and ensuring the survivability of such systems is of great importance for their existence and effective operation. The problem of ensuring survivability is especially relevant in special-purpose systems, where the cost of system failure can be too high. Tabl.: 1. Fig.: 5. Refs: 26 titles.
