What is the difference between switch hub and repeater?
Hub- Broadcasts data from one port to all other ports in the network. Repeater- Regenerates the input data which is subjected to attenuation. Switch- Intelligent device which sends data to a particular port.
Are hubs and repeaters the same?
Hubs and repeaters are basically the same, so we will be using the term "Hub" to keep things simple. Hubs are common today in every network. They are the cheapest way to connect two or more computers together. Hubs are also known as Repeaters and work on the first layer of the OSI model.
What is difference between switch and hub?
Hub and Switch are the network connecting devices, both help to connect various devices. Hub works at the physical layer and transmits the signal to the port. Switch route the information and send it over the network.
What is a hub and a repeater?
Hubs are a form of repeater for an Ethernet LAN which has multiple ports (they are sometimes also known as "multi-port repeaters" or "active star networks"). Each port of a hub has an RJ-45 connector able to accept a patch cable to connect to a wall outlet.
What is different characteristic between hub and repeater?
Hubs differ from repeaters in that they do not boost the incoming signals and are designed for multiple input lines, but the differences are slight. Like repeaters, hubs are physical layer devices that do not examine the link layer addresses or use them in any way. It is not an intelligent device.
When would you prefer hubs over repeaters?
i We would prefer hubs over repeaters when the distance is less. ii We would prefer bridges over hubs when we need to connect multiple networks. iii We would prefer switch over others network devices when want to segment networks into different subnetworks to prevent traffic overloading.
What is the purpose of a repeater?
A repeater is an electronic device in a communication channel that increases the power of a signal and retransmits it, allowing it to travel further. Since it amplifies the signal, it requires a source of electric power.
What is the purpose of switch hub?
A network switch (also called switching hub, bridging hub, and, by the IEEE, MAC bridge) is networking hardware that connects devices on a computer network by using packet switching to receive and forward data to the destination device.
Why are hubs better than switches?
Switches are more efficient than hubs, as they are better suited for connecting individual devices rather than connecting networks. It is designed to be an address-based connection, as they use the source and destination address for data transmission.
What are the advantages of using repeaters and hubs?
Advantages of the repeater:
- Repeaters can extend a network's total distance.
- A repeater is simple to connect.
- Repeaters do not seriously affect network performance.
- It is cost-effective.
- Certain repeaters can connect networks using different physical media.
Why are hubs no longer used?
Network Size
Hubs are unable to support networks that are as large as switches because hubs send all traffic to all devices on the network. The more devices you add, the slower the network gets, eventually becoming unusable.
What is one disadvantage of using repeaters?
Disadvantages of Repeaters
Repeaters cannot connect dissimilar networks. They cannot differentiate between actual signal and noise. They cannot reduce network traffic or congestion. Most networks have limitations upon the number of repeaters that can be deployed.

Can a repeater be used as a hub?
Hubs are a form of repeater for an Ethernet LAN which has multiple ports (they are sometimes also known as "multi-port repeaters" or "active star networks"). Each port of a hub has an RJ-45 connector able to accept a patch cable to connect to a wall outlet.
What is the advantage of using switch over hub?
A switch is preferred over a hub because a switch will only send message to device that needs or request it.
When would you use a hub over a switch?
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.
Why we dont use hubs?
Hubs are unable to support networks that are as large as switches because hubs send all traffic to all devices on the network. The more devices you add, the slower the network gets, eventually becoming unusable.

What is the disadvantage of switch 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.
Do I need a switch or a hub?
- If you have only a few devices on your LAN, a hub may be a good choice for a central connection for your devices. If you have the need for more connections, an Ethernet switch may be a better option over a hub.
Why not to use a repeater?
Network Bandwidth
The primary drawback of a wireless repeater is that it effectively halves the bandwidth for any computers connecting to it, rather than the primary router.
When should a repeater be used?
Repeaters are used to extend transmissions so that the signal can cover longer distances or be received on the other side of an obstruction. Some types of repeaters broadcast an identical signal, but alter its method of transmission, for example, on another frequency or baud rate.
What is one advantage of using repeaters?
Advantages of Repeaters
Repeaters are simple to install and can easily extend the length or the coverage area of networks. They are cost effective. Repeaters don't require any processing overhead. The only time they need to be investigated is in case of degradation of performance.
What is the 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.
What are 5 differences between hub and switch?
Key differences between hub and switch
The hub uses a half-duplex cable, whereas the switch uses a full-duplex cable. The switch is an active device, whereas the hub is a passive device. The switch employs the Spanning Tree Protocol to avoid switching loops. On the other hand, the hub cannot avoid switching loops.
Which is better hub or 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.
