New to Electronics! Conductors, insulators and semi-conductors

[OXGN88]

I am still reading my introductory book to electronics and some of the questions are a bit vague when looking back at the information provided throughout the reading. I understand the differences between conductors, insulators and semi-conductors, but the question in the book asks "Why is it essential to understand the relationship between conductors, semiconductors, and insulators?" I am wondering if this pertains to safety related knowledge since the very beginning of the book goes into electrical safety, which I did not go over. What do you guys think?

Read this free book, and try to understand purpose of each type of parts. Every part have purpose and reason way is used and when is needed. All is ok if you work on lower voltages, some parts should be sacrificed in purpose of learning, but if you are starter, then skip high voltage projects for now. For first projects you can use batteries, later some good adjustable power supply with transformer and fuse.
