Mobile Device Synchronization
You can synchronize these types of data between your PC and your mobile device:
Contacts Programs Email
Pictures Music Videos
To synchronize an Android device to a PC, follow these steps:
1.Install the synchronization software provided with the device on the PC.
2.Connect the device via USB.
3.Choose the Disk Drive option. (You might need to tap Mount on older devices to have the device show up in Windows Explorer as a removable-media drive.)
4.Start the synchronization software (see Figure 8-8) and choose what you want to sync.
Figure 8-8 shows an example of HTCSync software with the Android-based HTC EVO connected via USB and set to HTCSync. Note that the device has been renamed LampSmart.

Troubleshooting
Troubleshooting is the ultimate requirement for any computer or network technician: to apply the knowledge learned to solve a problem for a client. It is not surprising that the Troubleshooting domain is 36% of the CompTIA A+ Certification 220-802 exam, the highest percentage of any domain in this exam, and the second highest of all objectives on both the 220-801 and 220-802 exams (exceeded only by PC Hardware, at 40%).
The CompTIA Six-Step Troubleshooting
Process
This troubleshooting process is important to understand for two reasons: it’s on the exam, and it will save you a lot of time and frustration in your day-to-day work.
Here’s the basic outline:
1.Identify the problem: Question the user and identify user changes to computer and perform backups before making changes.
2.Establish a theory of probable cause (question the obvious).
3.Test the theory to determine cause. Once the theory is confirmed, determine the next steps to resolve problem. If the theory is not confirmed, reestablish a new theory or escalate.
4.Establish a plan of action to resolve the problem and implement the solution.
5.Verify full system functionality and if applicable implement preventive measures.
6.Document findings, actions, and outcomes.
Now, let’s take a closer look at how to accomplish these steps.
