A software update is a set of changes made to a piece of software to improve functionality, fix bugs or close security vulnerabilities. They are also sometimes referred to as patches. When these updates are released, software vendors usually post them on their websites for users to download and install. Keeping software updated is one of the most important ways to protect computers, phones and other digital devices from cybercriminals who target known vulnerabilities.
For example, a fitness app may receive updates to add new features like integration with other fitness tracking devices or bug fixes that prevent the app from correctly syncing data. In a business setting, customer management systems may get software updates to address security flaws, improve performance and user interface features, or ensure compatibility with newer web browsers.
If you’re running Windows, most programs have a Check for Updates function that connects to the developer’s website and looks for available updates. However, this is only a good option if the user has administrator privileges on their computer and regularly checks for updates manually. For most companies and schools, it’s best to use a patch management or software deployment solution to remotely push out updates and patches to each computer in the environment.
If you have an iPhone, iPad or Apple TV, most of your apps will get updates automatically through the App Store. You’ll be notified when updates are available and can choose to install them in the background while you work or play. If you’re worried about losing data, you can back up your phone or tablet before an update.
