| 1 | +# Digital Forensics |
| 2 | + |
| 3 | +## Scenario |
| 4 | + |
| 5 | +For digital forensics operations (digital evidence investigation), we want to develop an application that dumps the entire physical memory (RAM) of a modern operating system (such as Linux, Windows, macOS). |
| 6 | +We assume there is a dedicated interface of the operating system that allows reading of physical memory for dumping. |
| 7 | +The application can dump to a file or to standard output (for redirection to a file or network redirection). |
| 8 | +The result is a dump with the size of the physical memory (RAM) of the system. |
| 9 | + |
| 10 | +Answer the following questions with "True" or "False" and justify your answer. |
| 11 | +The justification should be simple, 2-3 sentences for each answer. |
