- Hub Defined – Hub is basically a common connection point for the devices in a network. The hubs connect the segments of a LAN, which consists of different ports, so when the packet arrives at a port, it’s copied to some ports to that every segment of the LAN may see all packets.
- Router Defined – Routers forward data packets along the networks. These are connected to at least 2 networks, commonly 2 WANs or LANs or a LAN and its network of ISP. The routers are located at the gateways, which are the places where 2 or more networks connect. The routers use forwarding tables and headers to determine the best possible path to forward the packets. They use protocols when communicating with one another and configure the right route between any of the 2 hosts.
- Switch Defined – When it comes to a network, the switch is actually the device that forwards and filters packets between the LAN segments. Switches operate at the data link layer and, other times, the network layer of the OSI Reference Model and support packet protocol. The LANs that use switches in joining segments are known as switched LANs or switched Ethernet LANs if it’s Ethernet networks.
Several technicians have the tendency to use the terms hub, switch, and router interchangeably, yet did you know that they have differences? The functions of such devices are different from each other, though there are times when they’re all integrated into a device.
