What is hub and its types?
What is hub and its types?
The hub has numerous ports. If a packet reaches at one port, it is able to see by all the segments of the network due to a packet is copied to the other ports….Difference between hub and switch.
| Hub | Switch |
|---|---|
| A hub works at the physical layer of the OSI model. | A switch works at the data link layer of the OSI model. |
Where are hubs used?
Hubs are networking devices operating at a physical layer of the OSI model that are 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.
What are different types of networking devices?
Types of network devices
- Hub.
- Switch.
- Router.
- Bridge.
- Gateway.
- Modem.
- Repeater.
- Access Point.
Do hubs have IP addresses?
As others have said, hubs don’t use IP or MAC addresses. They just mirror everything from every port to all other ports. Think of it this way. A computer can’t just say “hey I want to send this data over to that computer over there.” It has to be more specific by specifying an address.
How does an intelligent hub work in a network?
Intelligent Hub :- It works like active hubs and includes remote management capabilities. They also provide flexible data rates to network devices. It also enables an administrator to monitor the traffic passing through the hub and to configure each port in the hub.
How are data packets sent through a hub?
Hubs cannot filter data, so data packets are sent to all connected devices. In other words, collision domain of all hosts connected through Hub remains one. Also, they do not have intelligence to find out best path for data packets which leads to inefficiencies and wastage.
What are the different types of network devices?
1 Repeater. – A repeater operates at the physical layer. 2 Hub. – A hub is basically a multiport repeater. 3 Bridge. – A bridge operates at data link layer. 4 Switch. 5 Routers – A router is a device like a switch that routes data packets based on their IP addresses. 6 Gateway. 7 Brouter.
What’s the difference between a bridge and a hub?
A bridge is a repeater, with add on the functionality of filtering content by reading the MAC addresses of source and destination. It is also used for interconnecting two LANs working on the same protocol. It has a single input and single output port, thus making it a 2 port device. the stations is unnecessary.
