Here's a side-by-side comparison of their functions, how they work, and their structures: | **Aspect** | **RSS** | **Atom** | |---------------------|----------------------------------------------------------------------------------------------|-------------------------------------------------------------------------------------------| | **Function** | Primarily used for distributing updates to digital content. Often used for blogs, news, and podcasts. | Similar to RSS, used for web content syndication.
