Description:The last decade has seen an explosive rise in the number of network & security technologies, and the emergence of totally new related disciplines.

Keeping abreast of these developments represents a huge challenge to Irish corporate customers. It is an area with a very large potential payback but also presents significant business consequences if ignored.

Understanding the fundamentals of network selection, implementation and operation, will allow your organisation to deploy applications to all business units securely, while delivering cost efficiency and performance improvements.

Using vendor led certification training and self-study material as the primary source for personal development presents a difficulty in that there is typically a very narrow, product-specific focus.

The focus of the Trigraph Fundamentals of Networking course is to lay a product-independent foundation, which would facilitate the recognition of basic principles, and would encourage effective decision-making based on an independent, generalized application of specific topics. Our two-day briefing is designed to act as a primer for delegates on the key issues in selecting, deploying and operating modern communications networks.

One goal of this course session is to de-mystify the complex discipline of network design, using a product-independent approach, based on a holistic business and technology perspective. The four key topics explored in this briefing are :-

Wide Area Networking (WAN)
Local Area Networking (LAN)
Telephony (including IP Telephony)
Network Security
Main presenterThe key presenter is Donal O'Seaghdha - click here for more information on Donal
AudienceThis briefing is suitable for ICT and sales professionals who need a foundation course in network technologies. This will help attendees assimilate subsequent product-specific training and work experience more effectively, by defining a context for the associated skills and knowledge.

It is also appropriate for ICT managers, who want a fast-track introduction to emerging network technologies and how to derive maximum business benefit from them.
DurationTwo days
ObjectivesOn completion of this Briefing, delegates will:

• Be comfortable with network concepts and terminology
• Have a working knowledge of the different WAN, LAN, Telephony and Security solutions, equipment and services
• Understand how these technologies can be used by the organisation to gain competitive advantage
