Difference Between Hub and Switch

By Mohit Uniyal|Updated : April 20th, 2022

Difference Between Hub and Switch: Hub and Switch both are network connecting devices. The Hub device works at the physical layer and transmits the signal to the port to respond to where the signal was received while the Switch device enables connection settings and terminates them based on the requirement. A Hub allows multiple PCs to connect to a single network. HUB is used to connect segments of a LAN. A switch connects various devices together on a single computer network. This device also is used to route information and sent over networks in the form of electronic data.

Here, we will first briefly explore the Hub device and Switch device and then we will see the complete list explaining the difference between Hub and Switch devices. We have elaborated on the differences in various parameters below.

What is a Hub?

Before knowing about the difference between hub and switch we will see a brief introduction to the hub. A Hub is a device that allows multiple computers/PCs to connect to a single network. This device is used to connect segments of a LAN. A hub carries various ports so that when a packet/connection arrives at one port, that connection gets copied to various other ports. This device works as a common connection point for connecting devices in a given network. Hub has a speed up to 10Mbps.

There are two types of Hub: Active Hub and Passive Hub

Active hub: This is a kind of hub which have its own power supply. Active Hub can clean, improve, and relay the signal to the network.

Passive Hub: It is a kind of Hub that collects power supply from the active hub devices and wiring from nodes. It relays signals into the network without cleaning and boosting the signals.

An example of a Hub is a USB hub, that allows multiple USB devices to connect to a single computer.

What is a Switch?

The switch is a network device that is used to enable and establish the connection also it creates connection termination on the basis of requirements. This device is operated on the Datalink layer. In Switch packet/connection filtering is available. This is a type of device that has a full-duplex transmission mode. The switch is also called an efficient bridge. It connects several devices together on a single network and transmits the information. Its speed can be 10/100 Mbps, 1 Gbps, 10 Gbps

There are two types of Switch: Manageable Switches and Unmanageable Switches

Manageable Switches: These switches have a console port and IP address, that can be assigned and configured.

Unmanageable Switches: On these switches, configuration can’t be made. As there is no console port, It is impossible to assign an IP address on Unmanageable Switches.

Examples of Switch are ‘NETGEAR’ 5 port switch and a scissor-switch that is used with laptop computers.

What are the Differences Between Hub and Switch?

As we have seen a brief introduction about Hub and Switch devices. We will now explore the difference between Hub and Switch devices. The major differences between these two devices are explained in the table provided below:

Difference Between Hub and Switch

Hub

Switch

The Hub device is operated on the Physical layer of the OSI model.

While the switch device is operated on the Data link layer of the OSI Model.

This transmission is a broadcast type transmission.

This transmission is a Unicast, multicast and broadcast-type transmission.

It has 4/12 ports.

While switch can have 24 to 48 ports.

There is only one collision domain in Hub.

Different ports have their own collision domain. 

It is a half-duplex transmission mode.

It is a full-duplex transmission mode.

Packet filtering is not provided in Hub.

Packet filtering is provided in the switch.

Hub device cannot be used as a repeater.

A switch device can be used as a repeater.

Hub is basically not an intelligent device as It sends messages to all ports. Due to this, it is comparatively inexpensive.

The switch device is an intelligent device as it sends messages to selected destinations. Due to this, it is expensive.

It is simply an old type of device and nowadays is not generally used.

It is a very sophisticated device and nowadays widely used.

Hacking of systems attached to these devices is complex.

The hacking of systems attached to these devices is a little easy.

FAQs

  • The major difference between the Hub and Switch is that Hub devices work at the physical layer and are responsible for transmitting the signal to the ports to respond to where the signal was received while the Switch devices enable the connection setting and terminate them based on the requirements.

  • A Hub is a networking device that allows multiple computers or devices to connect to a single network. Hub is used to connect segments of a LAN. It contains various ports so that when a connection arrives at one port, that connection can share with various other ports. Hub has a speed of 10Mbps.

  • The switch is a networking device that is used to establish the connection among the computers or devices. Also, it creates connection termination on the basis of requirements. This device is operated on the Datalink layer. In Switch data connection filtering is available. The switch can connect several devices together on a single network. Its speed can be 10/100 Mbps, 1 Gbps, or 10 Gbps.

  • The difference between Hub and Switch is on the basis of ports. Generally, the Hub has 4 to 12 ports and it is simply an old type of device which is not generally used nowadays while the switch can have ports from 24 to 48 and is a very sophisticated device and widely used nowadays.

  • The two types of Hub are Active hub and Passive Hub.  The Active hub has its own power supply and can clean, improve, and relay the signal to the network. Whereas the Passive Hub collects power supply from the active hub devices and wiring from nodes. It also relays signals into the network without cleaning and boosting them.
