Question

what is the significance of backing up data on a computer?
backing up data allows you to browse the internet more quickly.
your computer will never become infected with a virus.
a copy of your work can be saved in case the computer crashes.
the web cache will be cleared regularly.

Explanation:

Data backup creates a duplicate of data. When the computer crashes (due to hardware failure, software issues, malware, etc.), the original data may be lost. But with a backup, the work (data) can be restored from the backup copy. Browsing speed (related to network, device performance etc.), virus prevention (needs antivirus software etc.), and web cache clearing (browser - specific operation) are not the main purposes of data backup.

Answer:

A copy of your work can be saved in case the computer crashes.
