What does CE, FCC actually means?

When I was studying my graduation course, I bought a scientific calculator. There are some logos (CE, FCC) behind the calculator. One of my friends told me that CE means “China Electronics”, but my friend was wrong. Actually, meaning of that logos are very different.

Every country has some standards to trade a product in that country. If any company wants to sell a product in the market, then that product must follow that country’s product standards. If product follows the standard then that product can be traded in the country. European Union Countries follows CE (European Community), United States follows FCC (Federal Communications Commission), and China follows CCC (China Compulsory Certification).
