What is HUB, How does it work, Types of HUB, Its Advantages and Disadvantages in detail.

ABOUT  HUB

(1) HUB is a Networking Device which is used to connect multiple computers, printers,             scanners etc within a computer network.

(2) HUB is used in small networks like LOCAL AREA NETWORK(Peer to Peer Network).

(3) There are many names of HUB like Ethernet HUB, Repeater, Active HUB, Dumb Switch     and Network HUB.

(4) Generally HUB Transmits Data Packets from one computer to another computer, that       means it helps in data communication. If it receives data packets from one port then it         broadcasts those data packets to all other connected computers in the network.

(5) According to Physical configuration looks  like Star Topology but logically it works as Bus Topology.

HUB with 8 Ports.
(6) Hub normally contains 8 to 16 ports.

(7) Traditional HUB provides bandwidth of 10 Mbps but now a days HUB supports bandwidth up-to 100 Mbps.

TYPES OF HUB

      There are 3 Types of HUB.

                (A)    Active HUB
                (B)    Passive HUB
                (C)    Intelligent HUB

(A) ACTIVE HUB::
           
        (i)  It consumes Electric Current.
        (ii) It amplifies the signal that means it increases the strength of coming signal.
        (iii)It does not support routing feature.

(B) PASSIVE HUB::

         (i)  It does not consume Current. 
         (ii) It does not amplify the signal that means it does not increase the strength of coming     signal. 
         (iii)It does not support routing feature.

(C) INTELIGENT  HUB::

         (i)  It consumes Electric Current.
         (ii) It amplifies the signal that means it increases the strength of  coming signal.
         (iii)It supports routing feature.

                                                HOW DOES HUB WORK

If "DEVICE-1" wants to  communicate with "PC-3"  then: 

    (a) data to be tocnsmitted  shall  be  converted into  small  data  packets.

    (b) Those  data   packets  are  transmitted  to  HUB.
  
    (c) HUB  transmits  these data  packets   to  PC-1,  PC-2,  PC-3.

    (d)  Data  packets   are    sent  to a  particular  address i.e IP  Address.
                               (IP:  INTERNET  PROTOCOL)

    (e) If IP address matches with the IP address of the computer then computer will accept all the data packets otherwise rejects them.

    (f) PC-1, PC-2 will reject but only PC-3 will accept all the data packets.


ADVANTAGES  OF  HUB

   (1) Speedy data transmission
   (2) No hurdle in communication
   (3) Increases the strength of the signlas
   (4) Less network breakdown
   (5) Cost effectiveness

DISADVANTAGES  OF  HUB

  (1) Collision of data Packets
  (2) High risk of lost communication
  (3) Smaller in network size
  (4) Not so Smart like Switch
  (5) Works on Half-duplex mode
