Resource for the key terms

So I'm not sure whether I should make a new post or post this to the Student Forum section but eh. Last year in ECE History I used www.history.com to help me define my key terms and I just wanted to throw that out there because it's easier than searching the far reaches of the internet to find information that looks pretty sketchy this site is usually really good at explaining the term and even helps with the significance sometimes. I just used to help me find and define the first few terms on our list so it's still pretty helpful especially now that we're talking about things that happened in history.
