This course introduces the basic principles of operating systems and discusses the important underlying concepts, including the problems of concurrency.
The purpose of this module is to provide a basic introduction to operating systems and the underlying concepts of processes, resource management, security, and concurrent systems. Software engineers should be aware of techniques associated with these concepts which are needed in applications other than operating systems.
At the completion of this module a student should:
1. Introduction to Operating Systems - 1 Lectures
A brief historical overview with examples of important systems. Different styles of operating system (e.g., real time, batch, program development). Operating systems as a vehicle for the portability of application programs. The gross structure of an operating system: layered architecture and its benefits for implementation and maintenance.
2. Program and Human Interfaces - 6 Lectures
Operating system services. Human interface, command languages. Introduction to UNIX: Structure, Program/User Interface
3. Processes and Concurrency - 6 Lectures
The idea of a process and its life history. Process control blocks, scheduling. Co-operating processes: exclusion, synchronisation, inter-process communication. Semaphores, monitors, messages. Multi-processing in Java, the thread model.
4. Resource Management - 5 Lectures
Different types of resources. Deadlock prevention and avoidance. Memory management. Segmentation, paging. Discard algorithms, thrashing. Associative stores.
5. Input-Output - 3 Lectures
Input-output services. Filing systems, disc space management, Distributed systems.
6. Security - 1 Lecture
Discretionary and mandatory security. User authentication. Encryption. System management.
