    Hi all

    as far as i understand the difference between Repeater,hub,bridge,
    switch,router and gateway are as follows , how correct is my
    understanding ?

    Repeater

    Forwards every frame it receives
    it is a generator,not an amplifier(i.e it removes noise &
    regenerates signal )
    Bi-directional in nature
    Useful in increasing ethernet size/length
    Maximum of 5 Repeaters in an Ethernet

    Hub

    basically a multiport repeater
    can be used to divide a single LAN into multiple levels of Hierarchy

    Bridge

    connect similar/dissimilar LANS
    Designed to store and forward frame
    Protocol independent
    Transparent to End Stations
    Operates in Layer-1 & Layer-2
    uses a table for filtering/routing
    does not change the Mac address in the frame
    two types of bridges are there Transparent/source routing

    Switch

    A fast Bridge.
    Common forwarding approaches used include Cut through,collission
    free & Fully buffered

    Routers

    Links dissimilar n/ws
    not transparent to end stations
    acts on a network layer frame
    isolates LAN to subnets to manage & control traffic

    Gateway

    uses Layer -7 Relay
