UNITED ELECTROTECHNOLOGIES
NETWORK CONCEPT TRAINER / LAN TRAINER (UE-LAN)
The world today has become unimaginable with out Internet or Mobile Phones or any sort of communication systems. Thanks to the Networking & Data Communication Systems that have paved their ways to embark their vital existence in almost every aspect of life
The scenario, expressing its inevitability towards the gigantic existence of the Network Systems, generates a need for the present generation to know, study & understand the principles of data communication & Networking
United Electrotechnologies, with its enormous exposure to the real world of technology, in an effort to share its expertise with the upcoming engineers, presents Network Concept Laboratory (NCT). The Network Concept Laboratory promises to impart basic concepts of networking, in a very simple, self-explanative & Practical way.
