My Automation and Control Technician Glossary

15 Electrical Engineering Technology terms

Hello, my name is Nicole and I live in Montreal. I am currently attending the fourth semester of the Electrical Engineering Technology - Automation and Control program. I made this glossary for students and beginners who have learned English words for programming and automation. It includes 15 key terms frequently found in lecture notes, technical papers and actual projects. For every word there is also the pronunciation, part of speech, a simple definition, a French translation, and an example of usage. I've chosen words from my coursework, lab work and trustworthy online dictionaries to help flesh this glossary as handy reference for study or later work.
