When an updated version of an app is available, you are notified either by message or by a visual indicator on the app icon.App updates are almost always no-cost and occur wirelessly over a Wi-Fi connection after you give your permission.If you bought your software recently and an upgrade is released soon after that, some software companies offer the upgrade to the latest version for free.
Read the information issued with the update and upgrade announcements to make sure your computer or mobile device and its operating system are compatible and won't suffer any repercussions.
It is represented as a series of numbers separated by periods.
The leftmost number in a software's version number represents major upgrades to the software.
This is because the internet applications may not need to place a software update on your computer or device to work properly.
In other cases, such as with Adobe Creative Cloud, you are notified when an update is available for the applications you previously downloaded, and you choose when to apply the update.
