A software update is a set of changes that updates, fixes, or improves the way software works. The changes are usually made to fix bugs, plug security holes, or add new functionality. Sometimes, an update can even limit or disable features if they’re no longer being supported by the developer or manufacturer of the software or device.
Many devices and applications will update themselves automatically when a notification is available. This might be through a push notification or a flag or bubble on the App Store, Google Play Store, Android, Apple Watch, tvOS, or Windows computer icon. It is also possible to update operating systems through the Settings app on iOS, iPadOS, and tvOS devices or System Settings on macOS. Typically, these apps will only install an update if it meets certain requirements. These might include the device being connected to Wi-Fi, having sufficient storage, and being powered on at a certain time of day.
For desktop applications, it is important to check for updates frequently and apply them as soon as possible. In addition, it’s important to use a good anti-virus program and keep it updated regularly, and it is also a good idea to create backups of data on a regular basis. The most vulnerable systems are those that haven’t been updated in a long time because hackers can easily find ways to break into them by exploiting old, less effective protocols. Software updates are the best defense against these cybercriminals.
