Hub Switch and Router are the most commonly used networking devices that are used to connect nodes such as PC, printer, scanner, projector, etc in a network. Here in this post, I am going to explain to you about what is the difference between Hub Switch and Router in Tabular Form. Hub is a networking device that operates at the physical layer of OSI model. It is the simplest networking device hence has a low cost.

The Differences between Hubs, Switches, and Routers

In an Ethernet network, there are some networking devices that play their roles at various levels such as hubs, switches and routers. The functions of the three devices are all quite different from one another, even if sometimes they are all integrated into a single device. The following part will focus on the topic—hub vs switch vs router, aiming to clarify differences among them. A hub contains multiple ports. When a packet arrives at one port, it is copied to the other ports so that all segments of the LAN can see all packets. Hub acts as a common connection point for devices in a network. A switch operates at the data link layer layer 2 and sometimes the network layer layer 3 of the OSI Open Systems Interconnection Reference Model and therefore support any packet protocol.

The Difference Between A Router, Switch and Hub

A Hub is a networking device that allows one to connect multiple PCs to a single network. A switch is a control unit that turns the flow of electricity on or off in a circuit. It may also be used to route information patterns in streaming electronic data sent over networks. In the context of a network, a switch is a computer networking device that connects network segments. A switch is effectively a higher-performance alternative to a hub. People tend to benefit from a switch over a hub if their home network has four or more computers, or if they want to use their home network for applications that generate significant amounts of network traffic, like multiplayer games or heavy music file sharing. Technically speaking, hubs operate using a broadcast model and switches operate using a virtual circuit model.

Some technicians have a tendency to use the terms router, switch and hub interchangeably, but have you ever wondered what the difference is? Some technicians have a tendency to use the terms router , hub and switch interchangeably. Have you ever wondered what the difference is among these devices? The functions of the three devices the router, switch and hub are all quite different from one another, even if at times they are all integrated into a single device. Which device do you use, and when do you use it? The router forwards data packets along networks. Routers are located at gateways, the places where two or more networks connect.


Routers. – Connect between LANs at “layer 3”, e.g., wide area. – Only send packet Segments can support separate transmissions hub hub hub switch/​bridge.


What’s the Difference Between Hubs, Switches & Bridges?

The key difference between hubs, switches and bridges is that hubs operate at Layer 1 of the OSI model, while bridges and switches work with MAC addresses at Layer 2. Hubs broadcast incoming traffic on all ports, whereas bridges and switches only route traffic towards their addressed destinations. Hubs provide a dedicated physical connection for every device, which helps reduce the possibility that a failure of one computer will cause all computers to lose connectivity. However, because a hub is still a shared bandwidth device, connectivity is limited to half-duplex. Collisions remain an issue as well, so hubs do not help improve the performance of the network.

The Hub and Switch are the networking devices which appear to be similar and physically used as a star topology. However, there are several differences between Hub and switch. The prior difference is that logically the hub works like a bus where the same signal is transmitted to all the connections.

The reason for the confusion is understandable. Besides looking similar, all three devices pass along data traffic through connectors called ports. Plus, as these devices become more sophisticated, the functional differences between them continue to blur.

In comparison, a switch keeps a record of the MAC (Media Access Control) addresses of all the devices connected to it. Unlike an Ethernet hub or switch that is concerned with transmitting frames, a router is to route packets to other networks until that packet ultimately reaches its destination.

Hubs do not differentiate between frame types, and thus will always forward unicasts, multicasts, and broadcasts out every port but the originating port. Ethernet.
