In an Ethernet network, there are some networking devices that play their roles at various levels such as hubs, switches and routers.

Hub vs Switch: What's the Difference?

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. Basically, a hub is a repeater with multiple ports.

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.

Hub vs. Switch

A Hub is a networking device that allows you to connect multiple PCs to a single network. It is used to connect segments of a LAN. A hub stores various ports, so when a packet arrives at one port, it is copied to various other ports. Hub works as a common connection point for devices in a network. Hub In this difference tutorial, you will learn, What is Hub? What is Switch?

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.

The Difference Between A Router, Switch and Hub

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.

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. On the other hand, the switch can provide the communication between any pair of ports. As a result, all the ports in the hub belong to the same collision domain while in switch the ports are operated on the separate collision domain. Number of ports 4 more or less 24 - 28 depending on the type of switch. Collision domain Only one Different ports have separate collision domain.

What Are Hub, Switch and Router?

Repeater — A repeater operates at the physical layer. Its job is to regenerate the signal over the same network before the signal becomes too weak or corrupted so as to extend the length to which the signal can be transmitted over the same network. An important point to be noted about repeaters is that they do not amplify the signal. When the signal becomes weak, they copy the signal bit by bit and regenerate it at the original strength. It is a 2 port device. A hub connects multiple wires coming from different branches, for example, the connector in star topology which connects different stations. Hubs cannot filter data, so data packets are sent to all connected devices.

Разве это не услуга. Сьюзан промолчала. Она поняла: все дело в деньгах. Она перенеслась мыслями в тот вечер, когда президент Джорджтаунского университета предложил Дэвиду повышение - должность декана факультета лингвистики. Президент объяснил, что преподавательских часов будет меньше, бумажной работы больше, - но гораздо выше будет и жалованье.

Его глушитель, самый лучший из тех, какие только можно было купить, издавал легкий, похожий на покашливание, звук. Все будет прекрасно. Приближаясь к пиджаку защитного цвета, он не обращал внимания на сердитый шепот людей, которых обгонял. Прихожане могли понять нетерпение этого человека, стремившегося получить благословение, но ведь существуют строгие правила протокола: подходить к причастию нужно, выстроившись в две линии.

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.
