Summary of Content

This module introduces the fundamental aspects of computer networking technologies, the architecture, structure, functions, components and models of the Internet and other computer networks. It uses the OSI and TCP layered model to examine the principles and interactions of protocols and services at the application, presentation, transport, network, data-link and physical layers with an emphasis on Ethernet LAN technology. Students will gain practical experience in the investigation of Internetworks in a programme of laboratory work and tutorial study.

Syllabus

-360b7 Principles of communications and how networks have changed our lives. Introduction to the concepts of networks, data, local area networks (LAN's) wide area networks (WAN's), quality of service (QoS), security issues, network collaboration services and Packet Tracer activities. -360b7 Focus on how networks are modeled using the OSI and TCP/IP models and the process of data encapsulation. -360b7 The Application layer. In this context explore the interaction of protocols, services and applications with a focus on HTTP, DNS, SMTP/POP, Telnet and FTP. -360b7 The Transport layer and focus on how TCP and UDP protocols apply to the common applications. -360b7 The network layer through the examination of concepts related to addressing, routing, path determination, data packets and the IP protocol. -360b7 Focus on network addressing in detail and learn how to use the address mask, or prefix length to determine the number of subnetworks and hosts in a network. -360b7 The data link layer and the protocols associated with it. -360b7 The Physical layer as well as the standards and protocols that manage the transmission of data across local media. -360b7 Examine the characteristics and operation of Ethernet as it has evolved from a shared media, contention-based data communications technology to today's high bandwidth, full-duplex technology. -360b7 Examine various media and the distinct roles they play with the devices that they connect, identify the cables needed to make successful LAN and WAN connections and learn how to use device management connections. -360b7 Understand the configuration process using the IOS.

Learning Outcomes

On completion of this module the student should be able to:Describe the importance of data networks, how communication works in data networks and the internet in supporting business communications and everyday activities.Describe the devices and services that are used to support communications in data networks.Compare and evaluate network protocol models to explain the layers of communication in data networks.Evaluate the operations and features of application and transport layer protocols and services.Evaluate the operations and featues of netwok layer protocols and services and explain the fundamental concepts of routing.Evaluate the operation of protocols at the data link and physical layers and explain how they support communications.Describe fundamental ethernet concepts such as media, services and operation.Build an ethernet network using basic devices, utilise common network utilities to verify network operation and analyse data traffic.

Teaching / Learning Strategy

The course material will be introduced through lectures, while practical exercises, based on the lecture material, will be given to students for their laboratory sessions. The laboratory sessions will be instructor-led, including a set exercise to be completed each week in laboratory time to form the overall coursework assessment. Tutorials will be used to help explain and elaborate on both the lecture material and the laboratory exercises.
