A DOI is an acronym for digital object identifier. It begins with a 10 and has a prefix and suffix. For example, 10.1000/182 .
The publisher of the digital article or book assigns the DOI to the content item to provide a consistent link to its location on the Internet in case the URL changes. They get the DOI from the International DOI Foundation.
The DOI is usually posted on the electronic article journal near the copyright notice.
Also, some of the article databases such as Ebscohost or ProQuest will include the DOI number within the citation record for an article.
Fore more information about DOI, see the International DOI Foundation's website.
