A ROUTER is a networking device that forwards data packets between computer networks. Routers perform the traffic directing functions on the Internet. A data packet is typically forwarded from one router to another router through the networks that constitute an internetwork until it reaches its destination node.
HUB is a network hardware device for connecting multiple Ethernet devices together and making them act as a single network segment.
A network SWITCH is a computer networking device that connects devices together on a computer network by using packet switching to receive, process, and forward data to the destination device.
FIREWALL is a network security system that monitors and controls incoming and outgoing network traffic based on predetermined security rules.
