| Module Description: |
Operating system software has had to solve a number of fundamental problems in order to provide fair and efficient services to the applications that run on a computer system. This module examines the detail of and solutions to those problems as implemented in modern operating systems. |
| Learning Outcomes |
| On successful completion of this module the learner will be able to: |
| LO1 |
Explain the solutions used in the scheduling of processes. |
| LO2 |
Discuss problems and solutions in virtual memory management schemes. |
| LO3 |
Outline the structure and management of a variety of file system types and input/output mechanisms. |
| LO4 |
Compare and contrast the solutions to process concurrency issues. |
| LO5 |
Use programs to emulate and investigate algorithms and methods used in solutions to operating systems problems. |
| Pre-requisite learning |
Module Recommendations
This is prior learning (or a practical skill) that is strongly recommended before enrolment in this module. You may enrol in this module if you have not acquired the recommended learning but you will have considerable difficulty in passing (i.e. achieving the learning outcomes of) the module. While the prior learning is expressed as named MTU module(s) it also allows for learning (in another module or modules) which is equivalent to the learning specified in the named module(s).

Incompatible Modules
These are modules which have learning outcomes that are too similar to the learning outcomes of this module. You may not earn additional credit for the same learning and therefore you may not enrol in this module if you have successfully completed any modules in the incompatible list. |
