A hub operates at the physical layer, reproducing an incoming data stream on one of its ports to all outgoing ports (flooding).  Switches operate at  the upper layers.  For example, bridges operate at layer 2, routers are layer 3 switches.  Switches forward incoming packets to output interfaces based on the packets destination address.

Hub : it is a communicating device

here data collision occurs

Switch: it is a multipleport hub

datacollision is less

A Hub is a Layer2 device. It is a Broadcast device which sends out the information to all the devices connected to it. It is a non-intelligent device which is used in smaller networks and increases the network traffic. A Hub is a multiport repeater.

A Switch is also a Layer2 device but an intelligent device which forwards packets based on the MAC address. It stores information in the form of CAM Tables (Content addressable Memory). It works on CSMA/CD by sensing the medium whether it is free before sending the packet. A Switch is a multiport- Bridge.

hub has layer 1(physical layer) device and it has one broadcastdomain and one collision domain. it works with shared bandwidth. it works with 0's &1's. it is a dummy device.

Switch is a layer 2 (datalink layer) device and it has one broadcastdomain and no.of collision domains.it works with fixed B.W. It is an inteligent device.

Hub it is not a intelligent device,it only transfer the data .

Wherelse switch it is a intelligence device,it see through the connection & give the confirmation of delivering the data.

Hub: Hub is considered as a dumb device. it works as an amplifier which transmit signals. ie. when one pc communicates via hub with another pc it transmit signal onto the network.

Switch: Whereas switch can be considered as a intelligent hub but this mainly works with MAC address (Media Access Control addressing) on the networks. ie. when one pc communicates via switch with another pc it transmit signal as well as mac address from source to its destination and information will only be transmitted to particular pc.

Do not related MAC with MAC OS.

Hub is broadcase, its can not maintain mac address and its sequential data processSwitch is unicast, its maintainanence mac address and its Parlor process

HUb Hub is Physiacle layer device and its is work like 0,10,1 and hus is having a one collision domain And one broadcast domainSwitchSwitch work on data link layer and its is working on mac addresss and its is having a no collision but broadcast domain remain same as Hub

Hub is a Physical layer devices that are really just multiple port repeaters. When an electronic digital

signal is received on a port, the signal is reamplified or regenerated and forwarded out all

segments except the segment from which the signal was received.

 

switch (1) In networking, a device responsible for multiple functions such as filtering, flooding,

and sending frames. It works using the destination address of individual frames. Switches operate

at the Data Link layer of the OSI model. (2) Broadly, any electronic/mechanical device allowing

connections to be established as needed and terminated if no longer necessary.

Hub is a broadcast device, it works on physical layer
Switch is a unicast device, it works on a data link layer....it is called intelligent hub..it keeps a switch table in which address is mapped to port to find mac addresss.

    Hub:Hub is a physical layer device. Hub is also called as multi port repeater.

  IT IS BROAD COST DEVICE.IT RECEIVE SIGNAL FROM ONE PORT TO BROAD COST  THE SIGNAL ALL THE SYSTEMS ON A NETWORK
 

 SWITH: SWITCH IS DATA LINK LAYER DEVICE.IT IS ALSO CALLED AS INTILLIGENT DEVICE. IT IS UNICAST DEVICE. SWITCH RECEIVE SIGNAL FROM ONE PORT TO SEND THE SIGNAL PARTICULAR DESTINATION SYSTEM USING MAC ADDRESS. 

    NOTE:SWITCH MAITAIN MAC TABLE .

Switch works on layer2 while hub works at layer1.
Switch does on Mac address while hub broadcast the packet to each node on n/w
Switch is full duplex (2 way communication) while hub is half duplex (1 way communication)

HUB:-Works at layer 1(physical) : It uses broadcast for packet forwarding. Slower than switch & router. It create one collision domain & one broadcast domain.


SWITCH:-Works at layer 2(Data link). - It uses IP address for packet forwarding. Faster than Hub, but slower than Router. Switch breakup collision domain, but create one broadcast domain.

switch- switch is a multiple collision Device.
switch is a work on layer 2 and layer 3 switch work on layer 3.
switch is a data broadcast send .
switch is multiple data send and receive at a time.
switch work on csma/ca .
switch is contain two table cam table and arp cashing .
switch work on full-duplex.

Hub- hub is connected a single device on a single port.
and work on csma/cd.
work on single collision domain.
at a time one packet send and receive .
work on half-duplex.

Switch, is prevent the collision domain, switch is faster than hub, function of switch,learning,filtering,Aging,and prevent layer two looping

A hub is a device which joins multiple devices together.
A switch is a combination of a hub and a bridge. Switch can interconnect two or more workstations , but like a bridge, it observes traffic flow and learns. When a frame arrives at switch, it examines the destination address and forward the frame out the one necessary connection.

Switch - 100 MBPS
Hub - 10 MBPS

Switch - Transmission and reception simultaneously
Hub - One time transmission

Switch - Costly (Efficient)
Hub - Cheap in cost

Hub is one collision domain and one broadcast domain, so only one device can transmit at any given time.

Switch is multiple collision domain i.e., one separate domain for each port, and one broadcast domain.

Hub made half duplex and switch made full duplex
hub made one collision domain but switch made very port collision domain.

HUB
1. Not intelligent 2. Passive Device 3. It works on physical layer of OSI model
4. Transmission mode: Half Duplex

Switch
1. It is Intelligent
2. Active Device
3. It works on data link layer of OSI model
4. Transmission Mode: Full Duplex

Hub is layer 1 device, work in physical layer and the communication between device are half duplex, all the device exist in on collision domain, switch is L2 device and every port a collision domain has concept of Mac address table, (cash)

Hub is a broadcasting device which may increase collision domain but switch is based on filter and forwarding and reduce collision domain.
