To provide learners with an understanding of Local Area Network (LAN) technologies and the delivery of a wide range of networked services across a LAN infrastructure.
LANs have become ubiquitous in all but the smallest of enterprises and their implementation has become the realm of skilled designers if the best advantage is to be made of available technology. Whist it is now the case that simple networks can often been installed by users with little previous knowledge, the design, implementation, testing and management of extended LANs requires considerable technical knowledge. The impact of LANs across an organisation can require upskilling of staff, changes to the physical environment and changes to commercial procedures. It also requires changes to the access, security and ownership of the data which passes across the LAN. In this unit learners will understand that consideration must be given to not only the physical LAN but the organizational culture as a whole. Learners will understand the importance of considering both physical and logical environments including network addressing, best use of media, and network segmentation. Learners will also study Quality of Service (QoS) in order to best manage the network traffic. Once a LAN is installed and operational learners will study methods of measuring and maintaining performance in a proactive manner using a range of tools.
