A software update is a process that improves or fixes a computer program or application. These updates can include new features, security patches, and bug fixes that enhance the overall performance and user experience. Regular updates help ensure that software runs smoothly and remains compatible with other systems. Users typically receive notifications when updates are available, and they can choose to install them immediately or schedule them for later. Keeping software up to date is important for maintaining security and functionality, as outdated software can be vulnerable to cyber threats and may not work properly with newer technologies.
