Why software updates necessary | why update software | Software update

Hello friends.
    Many people ask me that why software update necessary.  They tell me that if we don't update our software than it's work properly. So why we update application or software. So please read this article to know about why software updates are necessary.
  Software updates give us a better performance of the software. Software updates are totally depends on software developer. What we get by software update it's depend upon software developer. If software developer wants to give us some new features then if we update our software than we get those new features who developer gives us.
   In the software update the most important thing is our security flows. When a software developer release a new software so that time software have many types of bugs which bugs can be used by a hacker who wants to hack that software. Ex. if a software is related to our banking services then the software must bug free. Now many peoples ask me that what is bug? So a bug is a weak point of any software. If the software developer don't update our software then a hacker can be hack that software easily because hacker spends a lot of time with software to know it's weak point. And if the software is updated than it'll change in a new version and the hacker needs a lot of new time to hack that software. So this is the main reason to update a software.

      If you don't update your software or security patches then you can be hacked by any hacker. So you needs to update your software.
