Semester 1

Organiser: Dr David Edward Perkins

This module uses the “Introduction to Networks” section of the Cisco CCNA Routing and Switching course to introduce the architecture, structure, functions, components, and models of the Internet and computer networks.

The principles of IP addressing and fundamentals of Ethernet concepts, media, and operations are introduced to provide a foundation for the remainder of the networking curriculum. The module blends theoretical content with a range of practical exercises such as creating small local area networks (LANs), carrying out basic configurations for routers and switches, and implementing IP addressing schemes.

Indicative content includes:

• Networking concepts. LANs v WANs. Internet, Client-server, peer-to-peer,
• IP addressing. IPV4, IPV6, sub-netting, VLSM, default gateway
• Network devices. Router, switch, wireless access point (WAP)
• Testing connectivity. Loopback address, end-to-end connectivity, PING, Traceroute
• Networking protocols. OSI 7 layer model, TCP/IP 4 layer model, data encapsulation
• Network media. Copper (UTP, STP), Ethernet, Fibre-optic, wireless
• Media Access Control. Physical v. logical topologies. Star, extended-star, bus, ring, point-to-point. Half v. full duplex.
• Ethernet. MAC addresses, Address Resolution Protocol (ARP)
• TCP v UDP. TCP handshake, reliability, flow-control
• Application layer protocols. HTTP/HTTPS, SMTP/POP/IMAP, FTP, SMB, DNS, DHCP
• Basic network security

good

Equivalent to the range 60%-69%. Is able to analyse a task or problem to decide which aspects of theory and knowledge to apply. Solutions are of a workable quality, demonstrating understanding of underlying principles. Major themes can be linked appropriately but may not be able to extend this to individual aspects. Outputs are readily understood, with an appropriate structure but may lack sophistication.

excellent

Equivalent to the range 70%+. Assemble critically evaluated, relevent areas of knowledge and theory to constuct professional-level solutions to tasks and questions presented. Is able to cross-link themes and aspects to draw considered conclusions. Presents outputs in a cohesive, accurate, and efficient manner.

threshold

Equivalent to 40%. Uses key areas of theory or knowledge to meet the Learning Outcomes of the module. Is able to formulate an appropriate solution to accurately solve tasks and questions. Can identify individual aspects, but lacks an awareness of links between them and the wider contexts. Outputs can be understood, but lack structure and/or coherence.

1. Explain the benefit of layered networking models and the place of common network devices and protocols within the models.

2. Troubleshoot and verify connectivity in a small network.

3. Configure switches, routers and end devices in a small network.

4. Explain the role of common network devices in creating a data network

5. Explain the naming and addressing schemes used in data networks and the protocols which allow them to interact.

6. Create IPv4 and IPv6 addressing schemes.
