he field of computer Forensics Analysis involves identifying, extracting, documenting, and preserving information that is stored or transmitted in an electronic or magnetic form (that is, digital evidence)
Forensics Analysis – Volatile Data:
- The data that is held in temporary storage in the system’s memory (including random access memory, cache memory, and the onboard memory of system peripherals such as the video card or NIC) is called volatile data because the memory is dependent on electric power to hold its contents.
- When the system is powered off or if power is disrupted, the data disappears.
