Hub is commonly used to connect segments of a LAN (Local Area Network). 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.
What is a hub in a computer?
A hub is the connection point in a computer device where data from many directions converge and are then sent out in many directions to respective devices. A hub may also act as a switch by preventing specific data packets from proceeding to a destination.
What is the difference between a wireless router and a hub?
It establish a simple connection between the networks in order to provide the data flow between the networks. Router transfers data in the form of packet is used in LAN as well as MAN.
Difference between Router and Hub :
| S.No. | Router | Hub |
|---|---|---|
| 1. | Router operates at the network layer of OSI model. | Hub operates on the physical layer of OSI model. |
Is a hub a router?
A hub and a router are both electronic devices used in computer systems networking. A router is a more sophisticated device with both hardware and software that is used to connect multiple area networks (LANs and WANs), or two or more logical subnets.
Comparison chart.
| Hub | Router | |

What is a hub for Internet?
An internet hub is a device used for connecting parts of a Local Area Network (LAN). The hub contains several ports, and when a packet reaches one port, it is copied to the rest of the ports so that all parts of the LAN can view all the packets.
Are hubs still used today?
Hubs are now largely obsolete, having been replaced by network switches except in very old installations or specialized applications. As of 2011, connecting network segments by repeaters or hubs is deprecated by IEEE 802.3.
How does a wifi hub work?
A wireless router, also known as a Wi-Fi hub, is the small electronic device supplied by your internet service provider that allows you to connect to the internet. It connects to your home broadband line and sends data from the internet cable to your internet-connected devices.
Why is switch better than hub?
Switch: A switch is smarter than a hub. Similar to the hub, it is a connection point for all the devices in the network. However, it is more efficient at passing a data packet across the network. It records the MAC addresses of the computers connected to it in a tabular format.
What are the 3 basic hub types?
There are three types of network hubs: passive, active, and intelligent.
Does hub use MAC address?
A Hub does not differentiate between MAC addresses, and indeed cannot. It does not have the software required to identify specific targets. A hub is essentially an unintelligent device.
How do hubs connect?
A hub is a physical layer networking device which is used to connect multiple devices in a network. They are generally used to connect computers in a LAN. A hub has many ports in it. A computer which intends to be connected to the network is plugged in to one of these ports.
Why do you need a hub?
A hub serves as the nerve center of your home automation system and ties all of your devices together. Now, most smart home devices, regardless of the protocol they use, are controllable with their own appand if they need a bridge or hub, they will typically come with one.
Do I need a Wi-Fi hub?
However, if you want a truly smart ecosystem that can control your home’s temperature, lighting, security, audio, video and more, a hub may be necessary. While Wi-Fi can connect, at most, a dozen or so devices into a network, Z-Wave and Zigbee can each connect more devices than you’re likely to ever need.
What is a disadvantage of a hub?
Hubs are at a disadvantage against switches in networking because hubs are unable to differentiate between the devices on the network. If one computer is trying to reach another on a hub-based network, the computer will send the message to every other computer on the network, consuming bandwidth for each transfer.
How many ports does a hub have?
Difference between Hub and Switch
| S.NO | HUB |
|---|---|
| 1. | Hub is operated on Physical layer of OSI model. |
| 3. | Hub have 4/12 ports. |
| 4. | In hub, there is only one collision domain. |
| 5. | Hub is a half duplex transmission mode. |
In what situation would you use a hub?
Hub and Switch Which One Should I Use and When
In a small network, where there are lesser users or devices, a hub can easily cope with the network traffic and is a cheaper option for connecting devices on a network.
Is a router necessary?
You do not need to have a router to use Wi-Fi as long as you’re not trying to share an Internet connection. The common consumer Wi-Fi router is actually a combination device that includes a network switch, a network router and a Wi-Fi access point.
Does a router need a phone line?
Wireless routers plug into modems, not phone jacks.The router needs a secondary piece of equipment — a modem — to make the Internet connection. DSL modems use phone lines to connect your network to the Internet, and the router connects to the modem, not the phone line.
Should I buy hub or switch?
By generating less network traffic in delivering messages, the Ethernet switch performs better than a hub in busy networks. For a small network with lesser users or devices, a hub can easily deal with network traffics. It will be a cheaper option for a network cabling.
What are types of hub?
There are three types of the hub that are given below:
- Passive Hub.
- Active Hub.
- Intelligent Hub.
Are hubs cheaper than switches?
Switch is more efficient than the hub. A switch can join multiple computers within one LAN, and a hub just connects multiple Ethernet devices together as a single segment.Since switch has a higher performance, its cost will also become more expensive.
