Quizplus · Accepted Answer

A firewall is a security software or hardware device that monitors incoming and outgoing network traffic based on predetermined security rules. It filters out unauthorized access and protects the network and computer from intruders. Routers, switches, and hubs are networking devices that help in the transfer of data between two or more devices but do not provide security like a firewall.
