48、 set of International Standards produced to facilitate the interconnection of computer systems. Its relation to other International Standards in the set is defined by the Reference Model for Open Systems Interconnection (IS0 7498). The Reference Model subdivides the area of standardization for inter
49、connection into a series of layers of specification, each of manageable size. The aim of Open Systems Interconnection is to allow, with a minimum of technical agreement outside the interconnection standards, the interconnection of computer systems: a) from different manufacturers, b) under different managements, c) of different levels of complexity, d) of different ages. IS0 8571 defines a file service and specifies a file protocol available within the application layer of the Reference Model. The service defined is of the category Application Service Element (ASE). It is concerned wi
