What is the difference between Ethereum and BSC?

Could you please explain to me in simple terms what the key differences are between Ethereum and Binance Smart Chain (BSC)? I'm trying to understand the fundamental distinctions in terms of their technology, scalability, and the types of applications they support. Additionally, how do they differ in terms of transaction speed, cost, and security? It would be helpful if you could provide a comparison of these aspects and perhaps even discuss the potential benefits and drawbacks of each platform. Thank you for your assistance in clarifying this matter for me.
