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?
