1 City University of Hong Kong Information on a Course offered by Department of Computer Science with effect from Semester A in 2012/ 2013 Part I Course Title: Fundamentals of Computer Networks and the Internet Course Code: CS3270 Course Duration: One Semester No. of Credit Units: 3 Level: B3 Prerequisites: (Course Code and Title) Precursors: (Course Code and Title) CS2161 Fundamentals of Web Technologies or CS2172 Fundamentals of Computing or CS2331 Problem Solving and Programming or CS2360 Java Programming or CS2362 Computer Programming for Engineers and Scientists or CS2363 Computer Programming or CS2372 Fundamentals of Programming or equivalent Equivalent Courses: (Course Code and Title) Exclusive Courses: (Course Code and Title) Part II 1. Course Aims: This course aims to provide an introduction to the major concepts in computer networks, including the structure and main protocols of the Internet. Students will come to understand basic data communication and the techniques of building computer networks. They will also develop an appreciation of the evolution of the Internet and how it has scaled to become the premier interconnection network of the world. 1

2 2. Course Intended Learning Outcomes (CILOs) Upon successful completion of this course, students should be able to: No. CILOs Weighting 1. identify and explore the key technologies used in communication networks especially in local area networks and the Internet; (if applicable) 2. solve simple analytical problems in data transmission and network configurations; 3 apply the concepts of layer architecture in assessing the placement of network devices, protocols and services; 4. describe the structures and protocols used in computer networks and justify their designs in the context of a global network; 5. analyze the application of network technologies in designated scenarios and explore how these technologies support real-life applications. 15% 25% 3. Teaching and learning Activities (TLAs) (designed to facilitate students achievement of the CILOs) Teaching pattern: Suggested lecture/tutorial/laboratory mix: 2 hrs. lecture; 1 hr. tutorial ILO # 1 (identify technologies) TLA Readings on technologies. Selected chapters from text / reference books will be recommended for each topic to help students participate in lecture discussions and bring questions they want answered. Lectures. Concept and general knowledge of computer network technologies and the Internet are discussed. Tutorials. Questions provide practice in identifying technologies used in LAN and the internet. Quiz. A mid-semester quiz will check students achievement of the learning outcomes. This will provide timely feedback on learning progress. Individual assignment on analysis of networks requires identification of various features of networks 2

3 2 (solve analytical problems) 3 (apply layer architecture and technology concepts) 4 (describe structures and protocols) 5 (analyse applications of technology) Lectures. Analysis of communication problems in networks is demonstrated. Tutorials. Designed cases /questions practice analysis. Individual assignment on analysis of networks. Students are required to answer analytical questions on network communication. Readings on application of layer technology Lectures. Concepts in placement of network devices, protocols and services technology are discussed. Tutorials. Designed cases /questions about layer architecture are discussed with students. Individual assignment on layer architecture. Students are required to answer questions on application of layer technology. Readings on structures and protocols Lectures. The structures and protocols used in computer networks are discussed. Tutorials. Designed cases /questions on the structures and protocols are discussed with students. Individual assignment. On structure and protocol. Students are required to answer questions on the structures and protocols used in computer networks. Case Study. Students explore the applications of network or communication technologies in their daily lives. This activity not only stimulates students interest in the subject matter but also helps them relate what they have learnt to the real world. The students will also have an opportunity to apply their knowledge to formulate creative solutions in the case study. 3

Weight of ILOs to Assessment Tasks Quiz Assignments Exam Total for course (approximate) CILO 1 CILO 2 15% CILO 3 15% CILO 4 35% CILO 5 15% 15% 15% 70% 100% B. Assessment Criteria of Each ILO ILO No Criteria 1 Clarity and correctness in describing and identifying the given technologies will measure measurement this CILO. 2 Solution of simple analytical problems using equations and concepts in data transmission systems and simple network configurations. Appropriate application of equations to new scenarios. 3 Correct recognition of the role of network devices and properly placement of the devices in the correct layers within the layered architecture. 4 Describe the structures and protocols used in the computer networks. Demonstrate ability to see the overall picture i.e. the interaction between protocols and structures not only within a particular protocol layer but potentially across multiple layers: Provide an integrated picture of the network protocols and structures. 5 Demonstrate a comprehensive analysis of the applications of network technologies in given scenarios. Provision of a clear explanation and justification on how these technologies can be applied in real-life application. Remarks on weighting 15% 25% 4
