What is a router?

A router is the most intelligent device, it connects two networks together, for example a LAN to a WAN. It makes decisions about which Internet traffic will follow. Routers use headers and a forwarding table to determine where packets go and they use protocols such as ICMP to talk to each other and configure the est route between any two hosts. You are able to configure a router to block ports or allow ports, routers are also used as firewalls to protect your network.

What is a switch?

A switch is a lot like a hub, it is a device that connects multiple nodes (computers) together with a few differences. A switch is a more intelligent device than a hub, unlike hubs switches are able to check packets being sent and recieved. Switches support 10Mbps, 100Mbps, 1000Mbps. Switches utilize network bandwidth much more effectively than hubs ever did.

What is a hub?

A hub is a device that connects a number of devices or nodes (computers) together. It acts as a central unit. You would normally see a hub hidden away because there as usually so many Ethernet cables plugged into it.
