Hey there,

can someone tell me what the difference is between: switches, routers, hubs and bridges???

thank you

RE: difference betwwen: switches - routers - hubs

well, a router is connecting a network to shared resources such as internet, a printer, etc.  A hub is connecting two computers together and generally it's the building block of a typical network.  Usually a hub will be connecting a network of computers to a router with internet access or to another network via another hub or switch.  Switch is like a hub but it is often used to connect two or more hubs or even in place of a hub.  Its advantage is that it transfers data faster and better.  For example a hub will split the bandwidth of internet access evenly where as a switch will allow two computers to have the same bandwidth.  I am not sure about a bridge but I think is the connection (expansion) between two networks.  I personally have a router for internet and a switch that hooks up my pcs.  Of course nowadays it is not uncommon to find a router with a build in switch.  If you are serious about setting up your own network, buy a router with a build in switch.  


RE: difference betwwen: switches - routers - hubs

I think a bridge is a generic term for hubs and switches.

RE: difference betwwen: switches - routers - hubs

A repeater receives a packet of data and then reproduces it, like an amplifier. A bridge receives a packet and then retransmits it on only the port where the destination is known to be (mac address). A hub is a multiport repeater.
A switch is a multiport Bridge. A router receives and transmits packets at a higher level of the OSI model and works on IP ,IPX , or protocols not on Mac adresses.

RE: difference betwwen: switches - routers - hubs

A router is commonly reffered to as Layer 3 switch, a switch is commonly reffered to as a layer 2 switch, a bridge can be a PC, Router, etc.  Considering also the bandwidth splitting or conservation parameter.  See also previous replys.
But with the advent of new technologies, the differences are becomming less obvious.

RE: difference betwwen: switches - routers - hubs

can anyone tell me switch works on which layer

RE: difference betwwen: switches - routers - hubs

the easyes way to think about it is
a hub is the most basic... when it recives a signal it simply repeats it to all other ports.
a switch recives a signal and looks for where it goes... i decides which port to repeat it to by searching a directry of MAC addresses
a Router works as a border between networks or the internet.  it recives a signal and looks at the IP address [or other protocal that may be in use] and decides if it should send it to the other network
routers also work for translators between networks not all subnets can not "talk" to eachother without a translator.

im not going to go into ISO levels or such cuz frankly i forgot most of them

RE: difference betwwen: switches - routers - hubs

A switch is commonly on Layer 2 of the OSI Model
