Synchronization of your PDA with your computer

• A. is only necessary once a month
• B. is necessary to ensure both tools have the same data
• C. assures that you have a backup copy of your data
• D. both b and c

Answer: (D)

Synchronizing your PDA with your computer is about keeping data in sync across devices and providing redundancy for your information. When you synchronize, updates made on one device are transferred to the other, so both tools reflect the same data. That parity is important because it means you’re always working with the latest information no matter which device you’re using.

At the same time, having data living on both devices acts as a form of backup. If one device fails, is lost, or becomes corrupted, you still have copies on the other device, helping you recover quickly. It’s not about doing this only once a month; the benefit comes from the ongoing synchronization that maintains consistency and redundancy as changes occur.

So the best answer combines these ideas: synchronization ensures both tools have the same data and provides a backup copy of your data.
