AUDIENCE:   This course is for personnel responsible for the selection, planning, installation, operation and administration of local area networks. However, the course is suitable for anyone who wishes to understand the basic concepts surrounding local area networks. PREREQUISITES:   While this course assumes no prior knowledge of LAN systems, previous use or understanding of PC systems would be helpful. Delegates may find the information supplied in our PC Support class provides the ideal grounding for this LANs fundamentals course. DURATION:   4 days. Hands on. OBJECTIVES:   The course provides a balance between theory and practical information regarding LAN operations and integration into other networks. The theory concerns the various network architectures, protocols and underlying network operation, while practical information is provided by looking at specific network implementations and the cost and performance considerations of specific hardware and software.
