Computer maintenance refers to the regular tasks performed to keep a computer system running efficiently and effectively. This includes activities such as updating software, running antivirus scans, and cleaning hardware components. Proper maintenance helps prevent issues like slow performance, data loss, and security vulnerabilities. Another important aspect of computer maintenance is backing up data. Regular backups ensure that important files are safe in case of hardware failure or accidental deletion. Additionally, organizing files and uninstalling unused programs can improve system performance and free up storage space, contributing to a smoother user experience.
