Electronics Terminology

Technical language barriers are quite commonplace today, and most of us have been confronted with at least a few elements of such a barrier from time to time. Advances in technology, and the introduction of new or unfamiliar product areas, all require an expansion of our technical vocabulary if we are to communicate effectively. Hopefully, this edition of the Glossary will serve as a valuable reference for improved communications.
