Operating Systems

COMP15212 Operating Systems 10 Semester 2 Undergraduate Level 1 Stephen Pettifer Unit coordinator Department of Computer Science 1 FHEQ level (Framework for Higher Education Qualifications) ' First part HE study/Bachelors ' European Credit Transfer & Accumulation System Rating : 5.0 An operating system is typically the 'lowest' layer of software in a computer. It provides an abstracted interface so that applications can run on diverse hardware without modification and it provides security which prevents misbehaving software from crashing the hardware or disturbing other tasks which may be running simultaneously.This course unit provides an introduction to the major principles of implementation of an operating system and some experience in how these features may be exploited by the 'higher' software layers.   An operating system is typically the 'lowest' layer of software in a computer.
