Which of the following describes a form of digital communication?

Emails are a fundamental form of digital communication because they utilize the internet and digital technology to send messages and files between individuals or groups. Unlike traditional methods of communication that depend on physical delivery, emails allow for instant sending and receiving, making them a fast and efficient means of exchanging information. They can also include attachments, hyperlinks, and multimedia elements, enhancing their functionality beyond simple written communication. This characteristic is what distinctly categorizes emails as a digital communication method compared to other options that either do not utilize digital channels or are more rooted in physical or analog processes.
