Introduction to Networks covers networking architecture, structure, and functions. The course introduces the principles and structure of IP addressing and the fundamentals of Ethernet concepts, media, and operations to provide a foundation for the curriculum.

Learning Outcomes

On completion of this module the learner will/should be able to;


Describe the structure of a network, including how data flow from source to destination.


Define the layers of the OSI model along with their functions and protocols used in the data communication process.


Describe and implement an IPv4 and IPv6 addressing and naming schemes in network communications


Install, configure and troubleshoot a simple network using routers and switches.

Teaching and Learning Strategies

Simulation-based learning activities promote the exploration of networking concepts and allow students to experiment with network behaviour.

Hands-on labs help students develop critical thinking and complex problem solving skills.

Module Assessment Strategies

Formative assessment - 11 CCNA Introduction to Networks quizes held on a weekely basis worth 50%. Students will be allowed to choose their best 9/11 quizes.

A summative practical exam on packet tracer to test the students ability to configure and troubleshoot a network to meet the CCNA Introduction to networks requirements, this will be worth 50% CA.

Repeat Assessments

Repat quizes and/or practical to examine the learning outcomes that have not been achieved.

Indicative Syllabus

Ethernet Technologies

  • Ethernet sublayers
  • Ethernet MAC addrress
  • ARP
  • Fixed and Modular Switches
  • L2 and L3 switches 

Network Layer

  • Network layer protocols and services
  • Role of router in End-to-End connectivity
  • Configure a router with basic configurations.

IP Addressing

  • IPv4 address, subnet mask
  • Unicast, broadcast, and multicast IPv4 addresses.
  • Public address space and private address space.
  • IPv6 addressing
  • Types of IPv6 network addresses.
  • Configure global unicast addresses.
  • Role of ICMP in an IP network. (Include IPv4 and IPv6.)

Subnetting Networks

  • Why routing is necessary for hosts on different networks to communicate.
  • Calculate the number of host addresses available.
  • Calculate the necessary subnet mask in order to accommodate the requirements of a network.
  • Benefits of variable length subnet masking (VLSM).
  • How IPv6 address assignments are implemented in a business network.

Transport Layer

  • Characteristics of the TCP and UDP protocols
  • Port numbers and their uses
  • TCP session establishment and termination processes
  • How TCP protocol data units are transmitted and acknowledged to guarantee delivery.
  • Explain the UDP client processes to establish communication with a server.

Application Layer

  • Functions of the application layer, session layer, and presentation layer 
  • How common application layer protocols interact with end user applications.
  • Application layer protocols - DNS and DHCP, HTTP, FTP, SMB.
  • Explain how data is moved across the network, from opening an application, to receiving data.

Its a Network

  • Devices and protocols used in a small network
  • Basic security measures on network devices.
  • Security vulnerabilities and general mitigation techniques.
  • Configure network devices with device hardening features to mitigate security threats.
  • Troubleshoot using ping, trace and show commands to establish relative network performance.
  • Use the basic host and IOS commands to acquire information about the devices in a network.
  • Apply the commands to back up and restore an IOS configuration file.
