CSC2025 : Operating Systems

Semester 1 Credit Value: 20
ECTS Credits: 10.0


To provide an introduction to Operating Systems: concepts, structure and mechanisms.

The module will provide an overview of operating systems and systems programming with a focus on: the process model, scheduling, memory management and inter-process communication.

Assessment Rationale And Relationship

The written examination will test the students' depth of knowledge of the structure of common operating systems. The coursework will assess their systems programming ability, and their understanding of and ability to modify an operating system implementation.

Study abroad students considering this module should contact the School to discuss its availability and assessment.

N.B. This module has both “Exam Assessment” and “Other Assessment” (e.g. coursework). If the total mark for either assessment falls below 35%, the maximum mark returned for the module will normally be 35%.
