When an Android device is connected to computer, Windows automatically and immediately recognizes the device and a number of features appear on the device screen.
*PC Connection Options on Android device*
The first option of-course is default, whether you choose on just charging the phone or not it will automatically charge till the device stays connected via USB. For now we are not discussing the second option, though we will discuss it later.
Now, as far as the third option is concerned i.e. "Disk Drive" when you want the memory card content of your device to display in Windows: you choose this option. When you opt for this option, the device connected will show as a removable disk and you can go ahead with copying the facts to and from computer to your device.
The next two options show USB Tethering and Internet Pass Through option. As already explained in this section USB tethering enables the mobile device to share its cellular network with computer because, Internet Pass through lets you use the internet connection of computer.
All these options discussed at first because none of these options used in synchronizing the data from to PC. This is where we will discuss the second option which says "HTC Synch", this option allows you to synch data from your device to computer-but not without caveat. This is because data synching requires software installed. There's variation in the software and connection name, which will be according to the manufacturer. The device used here is HTC Evo Smartphone.
The synchronization software's have variable requirements e.g. Windows XP, RAM of 1 GB (or more), 2.0 minimum USB ports, space of 300 MB. The software can be download for free from the provider's website.
On HTC Evo the synch features enables you synchronize pictures, music, bookmarks, calendar etc. This process can be initiated either from programs on computer or from the device itself. If and when you use the built in email programs and contacts of the mobile, the same information gets transferred to computer's matched programs.
There are of-course people who use Gmail directly from Android platform instead of downloading software. This let's Google synchronize contacts, Calendar, and mails automatically and is viewable through PC or the device (when Gmail is connected). When you plan on choosing the direct usage of Gmail through Android platform, make sure that the password strength and that you change it monthly because data gets stored on Google server and security has good chances of being compromised.
Tools which are provided by third-party for synchronization of data include: Space/Mark for synchronizing Android device to MAC or PC through WiFi or Bluetooth, Exchange ActiveSync for synchronization of contacts, emails, and Calendars from 2.0 Android devices to Exchange Server.
