Question

What are the differences between hub, switch, repeater, router, bridge and gateway? I need a comparison table format thanks ! example characteristics like , layer, purpose, functionality, number of ports smth like that.. This is an example for hub and switch comparison, i need one for all 6 devices

Explanation / Answer

Physical Layer. Hubs are classified as Layer1 devices

per the OSI model.

Data Link Layer.Network switches operates at

Layer2 of the OSI model.

Physical Layer, Repeater works only at the

Physical Layer of the OSI model.

Bridging occurs at the physical and data link layer of the

OSI model.

Application Layer.Most gateways operate at the application layer,

but can operate at the network or session layer of the OSI model.

network device that provides interconnectio

n with other bridge networks

To connect a network of personal computers together,

they can be joined througha certain hub.

Allow to connect multiple devices and port can be manage,

Vlan can create security also can apply.

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.

A router is a networking device that forwards data packets between

computer networks. Routers perform the traffic directing functions

on the Internet. A data packet is typically forwarded from one router to another router through the networks that constitute an internetwork until it reaches its destination node.

A bridge is a device that connects and passes packets between two

network segments that use the same communications protocol.

Bridges operate at the data link layer (layer 2) of the OSI reference model. A bridge will filter, forward or flood an incoming frame based on the MAC address of that frame.

A gateway is a node (router) in a computer network, a key stopping point

for data on its way to or from other networks. On the Internet, the node

that's a stopping point can be a gateway or a host node. A computer that controls the traffic your Internet Service Provider (ISP) receives is a node.

An electronic device that connets 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.

A switch is considered more advanced than a hub because

a switch will on send meg to device that needs or request it.

A repeater is a network device that is used to regenerate

or replicate signals that are weakened or distorted by transmission over long distances and through

areas with high levels of electromagnetic interference (EMI).

A router is a networking device that forwards data packets

between computer networks. Routers perform the traffic

directing functions on the Internet. A data packet is

typically forwarded from one router to another router

through the networks that constitute an internetwork until it reaches its destination node.

Collisions occur commonly in setups using

hub.
