Electronics is essential to the modern world of instant global
communication. The subject has a history going back 60 years or
more, but it is only in the last 30 years that electronics has become
indispensable in the form of powerful and low-cost computers accessible
to all. Applications include: digital media for audio and video
storage and reproduction; satellite navigation systems which can
pinpoint a location anywhere on earth to within a meter; digital
cameras and camcorders at affordable prices; and automated manufacturing
that makes many products reliable and inexpensive.
Telecommunications have been revolutionized by modern electronics,
making possible worldwide instant telephony with automated international
dialing and, of course, the internet is possible only because of
advanced optical communication which links the continents with sufficient
capacity to carry all the intercontinental internet and telephony
traffic over submarine cables. None of this would be possible without
the technology, but it is also the design and development engineers
and graduates in electronic engineering and telecommunications engineering
that make possible the products that we all use, directly or indirectly,
in our daily lives.
Demand for telecommunications engineers is high throughout the
world. The profession offers a range of careers from design and
development to marketing, management, production engineering and
applications engineering. Graduates also find employment in other
disciplines because of the highly numerate nature of the subject.
