Networking Fundamentals
	Course description The field of data communications is undergoing tremendous change, spurred by the growing availability of sophisticated "off-the-shelf" hardware, software and network components. The challenge of integrating sophisticated technology into products, systems and services means that technical professionals must develop a solid foundation and state-of-the-art expertise in data communications and networks. This 2 day course provides you with a thorough introduction of how the basic networking components work and how they are put together to implement a system. Who will benefit?   Course Content Anyone, although the course is particularly aimed at non-technical personnel needing some knowledge of networking.   What are networks? Networks and internetworks, what is a LAN and what is a WAN. Introduction to the OSI model LANS LAN standards, topologies, LAN choices. What is Ethernet?, 7 layer model, how Ethernet works, CSMA/CD, MAC addresses, frames, broadcasts. Ethernet Cabling UTP, Cat 5, fibre optic cable. WANS WAN architecture, Common WAN terms, Core vs access, service providers, relationship with 7 layer model, WAN equipment, how to choose a WAN. Dialup access technologies Modems, ISDN, BRI, PRI. VPNs Private networks, public networks, What are VPNs?, benefits of VPNs, tunnelling, encryption, IPSec. Hands On Throughout this course delegates will gain a better understanding of networking fundamentals as they develope a live Local Area Network environment consisting of router, switch, PC's and Server. All network devices will be pre-configured but delegates will prepare network cabling from raw materials.
