How switch is different from hub explain with example?

Hub and Switch are both network connecting devices. Hub works at physical layer and is responsible to transmit the signal to port to respond where the signal was received whereas Switch enable connection setting and terminating based on need. Hub works in Physical Layer. Switch works in Data Link Layer.

How does a hub communicate?

Network hub Each computer or device connected to the hub can communicate with any other device connected to one of the hub’s Ethernet ports. Hubs are similar to switches, but are not as “smart.” While switches send incoming data to a specific port, hubs broadcast all incoming data to all active ports.

What are the differences between hub and switch?

A Hub is a networking device that allows you to connect multiple PCs to a single network, whereas a Switch connects various devices together on a single computer network. A Hub operates on the physical layer, whereas Switch operates on the data link layer.

How does the switches and hubs work in a network?

Switches typically connect LAN segments, so hubs attach to them. Switches filter out traffic destined for devices on the same LAN segment. Because of this intelligence, switches make more efficient use of their own processing resources as well as network bandwidth.

Why do we prefer switch over hub?

A switch is preferred over a hub because a switch will only send message to device that needs or request it.

What’s the difference between a network switch and a hub?

An electronic device that connects many network device together so that devices can exchange data. A network switch is a computer networking device that is used to connect many devices together on a computer network.

How are broadcast messages sent to a switch?

Broadcast messages are sent to the destination MAC address FF:FF:FF:FF:FF:FF. If a switch receives a message that is sent to that destination MAC address then the switch knows it is a broadcast and will forward the message to every other connected port.

How does a switch work in a network?

The switch has a CAM table and it will match the address of the frame with one of the addresses of the CAM table. If the address matches, the switch known the particular port at which that address resides. So the Switch will forward that packet to that particular port and this is also called as ‘Filter and forwarding’ in computer networks terms

What’s the difference between passive hub and manageable switch?

Passive hubs relay signals into the network without cleaning and boosting them. It can’t be used to extend the distance between nodes. Manageable Switches: Manageable switch has a console port and IP address, which can be assigned and configured.
