Operating Systems: Concurrent and Distributed Software Design

2.7. Object structuring within and supported by operating systems

Because object modelling is accepted as a standard approach to software engineering, many research projects have explored how objects might be supported by and used within operating systems. Object support operating systems are designed to support object structured software; but their internal structure need not be based on objects. Object-based operating systems use objects as their internal structuring mechanism. If the latter approach is taken, objects may be used to represent resources such as files, memory, processes, devices. A type manager may be used to manage each resource type and an object to represent an instance of a resource of that type. The system calls associated ...
