Description:
It is designed to equip its graduates for careers in the design, development and management of information networks. These can range from small company local area networks (LANs) to the global telephone and Internet networks, which are now converging towards a single entity. The program is very much concerned with the essential (but usually invisible) backbone or infrastructure of data communications systems that connects all the phones, faxes, computers and other multimedia service.
