A software update is a modification to existing computer programs that corrects security and functionality problems, improves performance or usability, or adds new features. Software updates are often provided by the original software publisher free of charge. The process of updating software is a key component to keeping computers and mobile devices safe from malware, viruses, and other online threats.
In information technology, a software update is also known as a patch, hot fix, or bugfix. Many software applications can be updated automatically, but this is usually only done when the application is not being used (for example, during a sleep cycle). IT departments may use management software to automate the update process for larger systems and data centers.
Most Windows operating systems use an automatic update feature called Microsoft Update, which checks for and downloads the latest patches and hot fixes. It’s important to keep this program updated to ensure your computer is protected against the latest cyber attacks and that all of your applications are working properly.
If you’re using an Apple device, you can update most of your apps and macOS through the App Store or Settings. You’ll be notified when an update is available for any of your apps, including those that don’t require regular updates (such as web browsers and antivirus software). Keeping your devices and applications up to date can help you avoid costly issues down the road. For example, if you don’t update your video game software, it may become vulnerable to exploits that allow other players to gain unfair advantages over you.
