A URL Scheme refers to the protocol or method used to access a resource on the internet, indicating how the resource should be retrieved or interacted with.
URL schemes are the prefixes in URLs, such as "http://" or "https://," defining the communication protocol to be used.
In the URL "https://www.example.com", "https" is the URL scheme.
Use appropriate URL schemes for different types of resources, consider security implications, and stay informed about evolving protocols.
