On successful completion of this module students should be able to:
be able to describe the major hardware components of a computer system and its peripherals (from chips and logic gates upwards).
be able to demonstrate their understanding of the types of function and facilities provided by Microsoft and Unix operating systems for users and programmers.
be able to demonstrate a practical understanding of the facilities available to script programmers using the UNIX environment, by bringing together various utility programs to solve a problem.
be able to describe fundamental issues, concepts, and challenges associated with operating systems.
The module is provided as an option for all Computer Science students but is also available as a service course.
Fundamental resources of a personal computer system. Architectural Block Diagram. Interaction through the OS and its interface components. Operating-system: definition and trivial examples of functionality. The Onion Skin Model as a simple view. Everything is a program. The idea of a system call, and the idea of the OS providing services.
2 Basic facilities of MS Windows and Unix operating Systems - 1 Practical
Introduction to the user interface facilities of both Microsoft Windows and Linux.
3. User interfaces and the OS - 6 Lectures
GUI'r and command line environments. X-windows and networked environments. UNIX tools: simple pattern matching and use of grep, sed, awk, introduction to BASH scripting.
4. Filestore, process and task management - 2 Practicals
Introduction to the filesystems and process control facilities of both Microsoft Windows and Unix.
5. Major operating system functionality ? files, processes (tasks) and memory management. - 5 Lectures
What files are. Reading and writing of files as services provided by the OS. Permissions and file-protection. The trash-can and file recovery. Physical file storage concepts. What is a process? Relationships of files, programs and processes. The OS and its components as processes. Schedulers and what they allow you to do. Multithreading. Concept of memory contexts and swapping. Difficulties (deadlock concept etc).The idea of interruption. Memory management. Swap-files and using disk as "extra memory". Allocation and deallocation of memory as a service provided by the OS. Fragmentation of memory.
6. UNIX tools and bash scripting and regular expressions - 5 Practicals
Working efficiently: practical use of the facilities Unix to support common application, computing, administration, and maintenance tasks. When to script rather than mouse around.
7. Storage Devices and peripherals - 3 Lectures
Magnetic, Optical, and solid state storage technologies (eg. 'rpod?, DVD and memory sticks). Disks, sectors and tracks. Fragmentation: differences between disk and memory.
8. Introduction to the basic building blocks - 5 lectures.
Binary numbers. Introduction to logic (AND/OR/NOT). Memory. Bus. CPU functions.
9. Learning support - 1 Practical
On-line self multiple choice questionnaire to assist in self assessment and to provide the students with a basis for their personal revision activities.
