Versions for this Unit:
Campus: Camperdown/Darlington
Pre-Requisites: None.
Co-Requisites: ELEC1601 AND (INFO1110 OR INFO1910 OR INFO1103 OR INFO1113). For most students, INFO1110 should have already been passed in semester 1.
Brief Handbook Description: The unit introduces principles and concepts of modern computer systems, including mobile computers and the Internet, to provide students with fundamental knowledge of the environments in which modern, networked applications operate.

Students will have basic knowledge to understand how computers work and are aware of principles and concepts they are likely to encounter in their career.

The material spans the low level (bits) to the high level (applications) concepts.

The unit covers:

*Principles of operating systems and the way applications interact with the OS, including operating systems for mobile devices

*Principles of computer networking

*Writing applications that use facilities of the OS and networking
Assumed Knowledge: A basic knowledge of Python is assumed.
Lecturer/s: Associate Professor Kummerfeld, Bob

(6) Communication and Inquiry/ Research (Level 2)
2. Produce clear written report
3. Able to extend their knowledge, acquire new knowledge, and connect to conceptual frameworks in operating systems and networks and the impact on application development, without explicit instruction
(2) Engineering/ IT Specialisation (Level 2)
4. Understand basic functions that an operating system performs, and know the main subcomponents of the OS

7. Understand additional concepts relevant for OS for server and for handhelds, including virtualization and containers
8. Experience with a number of different operating systems
9. Able to identify the interfaces at which users/applications can interact with the OS and the network, and identify where the OS function or network communication needs to be protected against unauthorized access
10. Understand major ideas used in internal implementation of OS and networks, such as caching, process structures, memory mapping, layering, reliable/unreliable transport, multiplexing, packet switching
11. Aware of some key algorithmic approaches that can be used in some subcomponents of OS and networking (eg routing, scheduling); also aware of alternative implementations in some cases, and of the tradeoffs involved
12. Able to write basic application functionality to interact with the operating system and the network, e.g. by opening and closing files, writing to disk, and sending application-layer data to remote applications
13. Aware of several major challenges that arise in distributed systems and mobile applications, e.g. failure tolerance and latency tolerance

Assessment Description: In the project, students must write some application code that accesses system facilities, and obtain some relevant, system-level measurements.

Weekly quizzes in lab will provide on-going checks that students are keeping up with the conceptual and factual content that is being delivered in lectures; the score will be based on the best 10 quiz marks.
Grade Type Description
Standards Based Assessment Final grades in this unit are awarded at levels of HD for High Distinction, DI (previously D) for Distinction, CR for Credit, PS (previously P) for Pass and FA (previously F) for Fail as defined by University of Sydney Assessment Policy. Details of the Assessment Policy are available on the Policies website at . Standards for grades in individual assessment tasks and the summative method for obtaining a final mark in the unit will be set out in a marking guide supplied by the unit coordinator.
Minimum Pass Requirement It is a policy of the School of Computer Science that in order to pass this unit, a student must achieve at least 40% in the written examination. For subjects without a final exam, the 40% minimum requirement applies to the corresponding major assessment component specified by the lecturer. A student must also achieve an overall final mark of 50 or more. Any student not meeting these requirements may be given a maximum final mark of no more than 45 regardless of their average.
Policies & Procedures: IMPORTANT: School policy relating to Academic Dishonesty and Plagiarism.

In assessing a piece of submitted work, the School of Computer Science may reproduce it entirely, may provide a copy to another member of faculty, and/or to an external plagiarism checking service or in-house computer program and may also maintain a copy of the assignment for future checking purposes and/or allow an external service to do so.
