Subject: Statement of Volatility Dell OptiPlex 3050_MFF
To whom it may concern:
The Dell OptiPlex 3050_MFF contains both “volatile” and “non-volatile” (NV) components. Volatile components
lose their data immediately upon removal of power from the component. Non-volatile components continue to
retain their data even after the power has been removed from the component. The following volatile and NV
components are present on the Dell OptiPlex 3050_MFF motherboard:
