Trivia: What is a program that prevents unauthorized access to private data?
The correct answer is Firewall
So why is this answer correct? : While a “fire wall” is a physical wall constructed to prevent the spread of fires in buildings, a “firewall” describes a program that protects users and their private data from being breached by an outside source via the internet. Businesses, hospitals, and government institutions use firewalls to prevent their systems from being hacked.
