Delivery This unit may be delivered as a stand-alone package or alongside other units such as Unit 12: Networking Technology, Unit 31: Networking Infrastructure. The learners must attend lectures, seminars, and group discussions. Most effort of the learners should be spent in research based activities to complete the assignment in this unit. Assessment There is an obvious need to combine practical and theoretical assessment. The theory can be delivered by using lectures, demonstrations and case studies that consider the goals of effective system administration. Learners can produce reports that describe features and show an understanding of the principles and definitions. The practical aspects provide an opportunity for learners to plan, install and maintain a client/server network. It is essential that a logbook is maintained for recording both progress and effectiveness. Links This unit provides a solid base of understanding of switching. This unit links with Unit 12: Networking Technology, Unit 31: Networking Infrastructure.
