The aims of this module are to introduce the leaner to the fundamental theoretical and practical aspects of traditional network provisioning. The module is about designing and building computer networks and involves the physical installation and commissioning of networks and connections to the internet. The module enables learners to maintain networks, including redesigning and upgrading them using CISCO network systems.
This module will ensure learners meet the following objectives:
- Explain the basics of data communications, backgrounds and concepts of computer networking.
- Describe the internet, how it works, its structures, and services provided.
- Be competent in configuring devices to take part in a network and connect to the wider internet
- Understand the legal requirements and standards in computer networking.
Introduction to Networks Configuring a Network Operating System
- Explain how multiple networks are used in everyday life.
- Explain how topologies and devices are connected in a small to medium-sized business network.
- Explain the basic characteristics of a network that supports communication in a small to medium-sized business.
- Explain trends in networking that will affect the use of networks in small to medium-sized businesses.
- Cisco IOS Software features, functions and initial configuration settings.
- Given an IP addressing scheme, configure IP address parameters on devices to provide end-to-end connectivity in a small to medium-sized business network.
Network Protocols, Network Access and Ethernet
- Explain how rules facilitate communication.
- Explain the role of protocols and standards organizations in facilitating interoperability in network communications.
- Explain how devices on a LAN access resources in a small to medium-sized business network.

Application and Transport Layer
- Explain how transport layer protocols and services support communications across data networks.
- Compare the operations of transport layer protocols in supporting end-to-end communication.
- Explain the operation of the application layer in providing support to end-user applications.
- Explain how well-known TCP/IP application layer protocols operate.
Build a Small Network
- Explain how a small network of directly connected segments is created, configured and verified.
