According to foreign media reports, when people still indulge in the unlimited ipad that was adopt with iOS 4.2 system last year, this week Apple released the latest generation of Apple's operating system iOS 5. However, what does the new operating system iOS 5 mean for the ipad? The iOS 4.2 system has introduced many new functions, such as multitasking, AirPrint (can support the direct connection with compatible printer file to ipad), Folders (file management tool), AirPlay (wireless technology), Game Center, multiple threads to send e-mail and so on. However, these functions did not truly change the use of the ipad, even its compatibility is not very well, for example, we cannot transfer mpeg to ipad directly, for we all know that the ipad only can support mov file and mp4 format. The release of iOS 5 likes a heavy hammer for the tablet computer ipad and once again subverts innovation, which is opening the new use of the ipad and also enhance the links between different Apple products, including iPhone, iPod touch and Apple TV and so on. Support the installation of iOS 5 It is gratifying that Apple did not forget its old users, not only can the latest equipment install the latest version of the system, iPad 2, an earlier version of the iPad, both of them can support the installation of iOS 5, not to mention the iPhone 3GS, the first three generations and a fourth-generation iPod touch. To updating the software needs to put the ipad to connect with the computer via the data cable and through iTunes to receive synchronously. After installing iOS 5, it will no longer need to connect with the computer USB synchronously. A major feature of iOS 5 is to upgrade software and sync information by the wireless network. Apple calls this feature is "out of the computer." Primary characteristics After installing iOS 5 on the ipad, you will first notice the new three icons on the screen: iMessage (instant communication), Newsstand (newspapers and magazines), Reminders (reminders). Apple gives the iOS devices users a real-time information solution by using iMessage, including the iPad, iPod and so on. With this feature, users can send messages to iPhone users by using the ipad. You can also share real-time text, photos or Screen. If you are sharing of this information through the wireless network, it is free. If it is 3G users, operators will charge a traffic fee. Application Notification Center The previous notification is whether you are using a mobile phone to do something, it will immediately notify to you by the form of pop-up window, which take screen-style aggression. This approach does not come back again. Of course, if you still want to keep this approach, you can change it in the settings. The iCloud provides a service not provided by other devices: it automatically backs up your data and settings, including camera settings, accounts, files, applications, and media buying. Therefore, if the iPad was lost, your data will be safely stored in the Apple iCloud.
