Final answer:
Unique identifiers of computer or network addresses on the Internet are called domain names, part of the URL used to access websites, distinguishing them from DOIs used for digital objects like journal articles.
Step-by-step explanation:
The correct term for unique identifiers of computer or network addresses on the Internet is domain names. Domain names serve as human-readable addresses for websites and are an essential part of the URL (Uniform Resource Locator), which is the address used to access webpages.
Unlike domain names, a DOI (Digital Object Identifier) is used for identifying digital objects, such as journal articles, ensuring the object can be located even if the URL changes. Domain names are a fundamental component of internet architecture, allowing for the easy identification and access to websites worldwide.
