Software documentation: Software documentation is a written text or visual representation that describes how a software application or system works, including its features, functionality, and usage instructions. It helps users, developers, and other stakeholders understand and use the software effectively.

Software upgrade: A software upgrade is a new version or release of a software application that includes significant improvements, new features, bug fixes, and performance enhancements. Upgrading software typically involves installing the new version over the existing one to take advantage of the latest enhancements.

Software update: A software update is a smaller, incremental release of a software application that includes minor improvements, bug fixes, security patches, and other enhancements. Updates are typically released more frequently than upgrades and are designed to keep the software running smoothly and securely.

Data backup: Data backup is the process of creating copies of important files, documents, and data to protect against data loss due to accidental deletion, hardware failure, malware attacks, or other disasters. Backing up data regularly ensures that you can restore your files and information in case of a data loss event.
