Answer 1

Firewalls protect confidential data by isolating registry data from the rest of the network and preventing users from accessing a particular website.

Step-by-step explanation:

Firewalls are used to protect confidential data by isolating registry data from the rest of the network and preventing users from accessing a particular website. Firewalls create a barrier between internal and external networks, monitoring and controlling incoming and outgoing network traffic based on predefined security rules. They effectively act as a gatekeeper, allowing only authorized and safe traffic to pass through.
