Types of Hub

Types of Hub:


•     Passive (do not amplify), concentration

•  Active (amplify), multi-port repeater


    Have many built in features and   protocols like SNMP support, virtual LAN support






     •Connect same type of networks

     •Increase length(as repeater)  

     •Add new node (join multiple LANS)   

     •Used to make connections at data link layer   of OSI

     •Control data flow

     •No configuration needs(plug and play) 

     •Repeater sends to all

     •Bridge sends message to selective segment    only

     •Read address of source and destination

     •So know physical location of source &         destination










     •Connects computers on a LAN

     •Work on data link layer

     •Identical to hub in shape but complex      in function

     •Slightly more intelligent than hub

     •Selective transmission.

     •Conserve bandwidth.

     •Support 10/100 mbps

     •Fast Ethernet switch provide     10/100/1000 standard.






    Available in different no of   ports
 To add larger no. of devices   make daisy chain.
