Question

Quizplus · Accepted Answer

A firewall is a combination of hardware and software that filters traffic between private networks or between a private network and a public network, such as the Internet. A cable is not a network device, it is a physical component used to connect network devices. A hub is a networking device that connects multiple devices together into a single network segment. A data switch is a device that connects multiple devices together and forwards data packets between them. While data switches can provide some level of filtering, they are not specifically designed for network security like a firewall.
