Engineers with limited exposure to data networks
Basic appreciation of TCP-IP, associated protocols and concepts. Engineers looking to consolidate and extend knowledge across all aspects of data networking both on a theoretical and practical basis.
Practical demonstrations: Each delegate will be shown how to manipulate the networking parameters of a windows based PC and the basics of vendor specific CLI.
Practical Exercises: The delegate will be expected to use a PC to log into an IS and configure several key parameters and identify the database structure.
Examination: Each delegate will be expected to complete a short multiple choice closed book exam along with a practical hardware based task under the invigilation of the instructor.
The candidate will be able to identify all major building blocks of data networks, protocols and the hardware used and their basic configuration. The meaning of all common acronyms and terminology will be explained and put into context. They will be able to configure a basic routed network and troubleshoot it.

I really enjoyed the course and the instructors were excellent in the way they put the course over. The facilities were excellent and the course was taught to a very high standard. - Neil Silcox
