For example, when you know that the food package in front ...

A Uniform Resource Identifier (URI), formerly Universal Resource Identifier, is a unique sequence of characters that identifies an abstract or physical resource, [1] such as resources on a webpage, mail address, phone number, [2] books, real-world objects such as people and places, concepts. [3]
Lists of acronyms contain acronyms, a type of abbreviation formed from the initial components of the words of a longer name or phrase. They are organized alphabetically and by field. They are organized alphabetically and by field.
