• C. A form of encryption
• D. A software installation process

Answer: (A)

In computing, backup refers to making a copy of data that is stored separately from the original. This process is essential for protecting information against loss due to various factors such as accidental deletion, hardware failures, or malware attacks. A backup can be stored on different mediums such as external hard drives, cloud storage, or other physical media, allowing for recovery of the data when needed. The concept of backup is a critical element in data management, as it ensures that important information can be restored to its original state even if the primary copies become damaged or irretrievable. Understanding how to perform backups and the different methods available is key for maintaining data integrity and security in both personal and professional contexts.
