Basic difference between Switch and hub

  HUBS
  Hubs repeat everything they
  receive and can be used to
  extend the network. However,
  this can result in a lot of
  unnecessary traffic being sent to
  all devices on the network. Hubs
  pass on traffic to the network
  regardless of the intended
  destination; the PCs to which the
  packets are sent use the address
  information in each packet to
  work out which packets are
  meant for them. In a small
  network repeating is not a
  problem but for a larger, more
  heavily used network, another
  piece of networking equipment
  (such as a switch) may be
  required to help reduce the
  amount of unnecessary traffic
  being generated.
  Switches
  Switches control the flow of
  network traffic based on the
  address information in each
  packet. A switch learns which
  devices are connected to its
  ports (by monitoring the packets
  it receives), and then forwards
  on packets to the appropriate
  port only. This allows
  simultaneous communication
  across the switch, improving
  bandwidth.
  This switching operation reduces
  the amount of unnecessary
  traffic that would have occurred
  if the same information had been
  sent from every port (as with a
  hub).
  Switches and hubs are often
  used in the same network; the
  hubs extend the network by
  providing more ports, and the
  switches divide the network into
  smaller, less congested sections

  To put it simply, hub lacks the intelligence of a switch. A switch actually learns the MAC addresses of the connected devices and puts them in a table.
  Eg., if a frame is received on port A with a source MAC as X, the switch makes a note of it, so that, it can forward the incoming frames with destination MAC as X to port A.
  Whereas in case of a hub, this is not possible and the hub ends up broadcasting the frame to all other ports.

  1. Switch is an intelligence device.Here packets are sent to the port the are meant for.
  Whereas hub lack that intelligence.It forward the packets to all the ports that are connected to the hub.
  2. Due to this intelligence cost of switch is higher than hub.

  Switch is nothing but an intelligent device , the purpose is same of both, just switch forwards packets to device to whom it is intended where as hub don't
  
  Technical Reason: Switch stores Mac address of each system where as hub not

  The term ‘hub’ is used to pass on to any piece of network equipment that connects PCs together, but it actually refers to a multi-port repeater.
  
  But Switches manage the flow of network traffic based on the address information in each packet.

  Hubs are repeaters
  Switches turn the connection between the computer and server on or off
