DOI (Digital Object Identifier) is a unique alphanumeric string used to permanently identify an object like a journal article or book. It provides a persistent link to its location on the internet. In contrast, a URL (Uniform Resource Locator) is a web address that provides the specific location of a resource on the internet. Key difference: DOI remains the same even if the web address changes, ensuring long-term access.
