as far as i understand the difference between Repeater,hub,bridge, switch,router, gateway are as follows , how correct is my understanding ?
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
basically a multiport repeater can be used to divide a single LAN into multiple levels of Hierarchy
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
A fast Bridge. Common forwarding approaches used include Cut through,collission free & Fully buffered
Links dissimilar n/ws not transparent to end stations acts on a network layer frame isolates LAN to subnets to manage & control traffic
uses Layer -7 Relay
