EC Council has defined digital forensics as a branch of forensic science that focuses on the recovery and investigation of material found in digital devices related to cybercrime. The term digital forensics was first used as a synonym for computer forensics. Since then, it has expanded to cover the investigation of any devices that can store digital data.
Although the first computer crime was reported in 1978, followed by the Florida computers act, it wasn’t until the 1990s that it became a recognized term. According to techopedia Digital forensics is the process of uncovering and interpreting electronic data. The goal of the process is to preserve any evidence in its most original form while performing a structured investigation by collecting, identifying, and validating the digital information to reconstruct past events.

There’s all kinds of stuff you can do with
dd if you research hard enough, but where it shines is in the ways it lets you play with partitions. But, because those filesystem archives aren’t complete images, they’ll require a running host OS at both ends to serve as a base.
dd, on the other hand, can make perfect byte-for-byte images of, well, just about anything digital. Check for more information here.
