Networking Technology
This is a 2-credit Unit intended for candidates who require a broad understanding of computer networking. It is designed to develop an understanding of the issues involved in the design, installation and maintenance of computer networks. On completion of the Unit you should be able to:
- Describe the characteristics of Local Area Networks
- Describe common networking media
- Describe the principles of cable testing
- Build a simple LAN
- Describe the features of Ethernet networks
- Define the operation of Ethernet Switching
- Describe IP addressing and routing
- Describe the operation of upper layer services
In the first part of the course, you will study how a host can connect to the Internet, basic networking arithmetic and number systems, terminology associated with networking, common networking models and bandwidth.
The second section covers the forms of media normally associated with networks. A description of how copper, optical, and wireless media may be utilised in networks is provided, as is a description of their characteristics.
The third section covers the basics of cabling a network. Cable testing basics and common problems are described prior to investigating LAN and WAN cabling.
The fourth section covers building a LAN and allows you to apply the knowledge gained during the earlier outcomes in a practical environment. You'll test and install LAN media, build a peer to peer network and build a small workgroup.
The fifth section covers Ethernet Fundamentals and introduces layer 2 operation. Specific implementations of Ethernet networks are examined in particular 10 Mbps and 100 Mbps Ethernet LAN. This forms the basis for study of newer LAN and backbone connectivity in the form of 1000 Mbps and 10-Gigabit Ethernet.
The sixth section covers switched Ethernet networks. Ethernet Switching is a growth area of LANs and is covered by reviewing the role of switched networks and the effect switches have on Collision Domains and Broadcast Domains.
The seventh section covers IP addressing. Common Internet Addressing is reviewed, along with how an organization can obtain an address. IP Routing Protocols are introduced to show how packets can be routed through the Internet. Subnetting is included to allow the design of an appropriate IP address scheme.
The final outcome covers the operation of the upper layers of the OSI model. This is designed to allow candidates to appreciate mechanisms used to deliver services to users at the Transport Layer and Application Layer.
There will be a closed-book multiple-choice assessment covering all outcomes. You will be presented with 50 questions and expected to answer 70% of these correctly. You will also be expected to keep a logbook recording the practical tasks you have carried out during the Unit. You must satisfy the requirements for these assessments in order to achieve the Unit.
