Local Area Network LAN and Intranet.

The system must study all the problems relevant to technologies, standards, equipment and
applications concerning the connection networks among PCs in 'local' environments (LAN).
Objectives: training of an installation and maintenance technician for Local Networks, able to:‐
know the principles, the standards and the devices that are normally used in LANs ‐ install LANs
and Intranets while following the cabling standards ‐ install the protocols and set the
configurations in the network PCs‐ maintain, troubleshoot and test LANs Educational Path: The
educational path of this Training Package must cover the following subjects: Local Area
