Digital literacy is part of media literacy. They’re both included in the idea of “information literacy,” which is the ability to effectively find, identify, evaluate, and use information. Digital literacy specifically applies to media from the internet, smartphones, video games, and other nontraditional sources. Just as media literacy includes the ability to identify media and its messages and create media responsibly, digital literacy includes both nuts-and-bolts skills and ethical obligations.
