Digital evidence is defined as information and data that are stored on electronic devices. This encompasses a wide variety of formats and types, including files, images, text documents, emails, and other types of data that reside on computers, mobile devices, servers, and cloud storage. The importance of digital evidence lies in its ability to help investigators uncover facts related to criminal activity, establish connections between individuals or events, and corroborate or refute testimony.

The option describing tangible evidence found on-site refers to physical items that can be touched and seen, like weapons or clothing, which do not fit the definition of digital evidence. Written documentation is also a form of evidence, but it is not specifically digital unless it is stored electronically. Limiting digital evidence solely to what is received via email is too narrow, as digital evidence includes a vast range of data types that go far beyond just email content.
