Practical Routers & Switches (including TCP/IP and Ethernet) for Engineers & Technicians

THE WORKSHOP

Routers and switches are primary components of most networks and obviously internetworks. Routers are simultaneously the most complex component of networks and the most important. This workshop goes through the basics of routers, routed and routing protocols and the basic rules to follow in building internetworks. If you are using any form of communication system or are applying modern PLCs/SCADA systems this workshop will give you the essential tools in working with networks. It is not an advanced workshop – but a hands-on one.
