Answer:
The answer is: Files and programs are accessed and stored on individual computers. Data is backed up by each individual when and how they choose.
Step-by-step explanation:
Benefit : Since files are stored separately in both computers, in any case that one of them malfunctioned or encountered a problem, the other one won't be affected.
Risk : As files are stored separately, back up process can take longer than usual. The IT staff must do the back up on each computer separately and thus, it requires lots of time and efforts.
