What is the difference between NFT and Ordinals?

Could you please elaborate on the key distinctions between NFTs and Ordinals? I'm particularly interested in understanding their uniqueness, use cases, and the manner in which they operate within the blockchain ecosystem. How do NFTs differ from traditional collectibles, and what makes Ordinals stand out? Additionally, could you discuss any potential advantages or disadvantages of each, and how investors or collectors might approach them differently? I'm eager to gain a deeper understanding of these two concepts and how they fit into the broader world of cryptocurrency and finance.
