Final answer:
Ava could have avoided losing all of her files if she had backed up her files. Backup is the process of creating duplicate copies of files and storing them in a separate location. By regularly backing up her files, Ava would have had a copy of her data stored somewhere safe, such as an external hard drive or cloud storage.
Step-by-step explanation:
Ava could have avoided losing all of her files if she had backed up her files. Backup is the process of creating duplicate copies of files and storing them in a separate location. This ensures that if the original files are lost or damaged, the backup files can be used to restore them.
By regularly backing up her files, Ava would have had a copy of her data stored somewhere safe, such as an external hard drive or cloud storage. In the event of a hard drive failure, she could have easily retrieved her files from the backup. It's always a good practice to regularly back up important files to prevent data loss.
Enabling firmware on her router, encrypting her files, and using an antivirus program are also important measures for computer security, but they wouldn't directly help in cases of hard drive failure or data loss.
