CV> I get Hub.
if you got hub, you also got switch.
Those 2 are almost identical.
a hub is cheaper and dumber :)
a switch is intelligent. It 'knows' which computer is connected to which
port, and so only echos the packet to that port.
a hub echos a packet to ALL ports.
So if you connect 4 computers to a switch,
computer 1 can send 100 MBit/s to computer 2,
and computer 3 can send 100 mbit/s to computer 4.
(theoretically on a 100 MBit network)
a hub can't do that, because the traffic of the whole network can't exceed
100 MBit. (and performance also suffers from more retries because of packet
collisions)
CV> I GET Bridge.
I don't agree fully with Bernies description.
A bridge interconnects 2 segments, so that they look like one.
A bridge knows which computer is on which segment, and forwards the packets
accordingly, but it will also forward broadcasts, so that the 2 segments
look like 1.
CV> I still think the other three can all be the same box. :(
I also don't know the exact difference between router and gateway
as I understand it:
a router is a special device (usually not a 'normal' computer) which routes
packets according to its routing table.
gateway: computer or device which handles routing for one network.
usually the gateway has the 1. available IP.
So on the network 192.168.0.0 the gateway is often 192.168.0.1
it handles all the traffic which is not local.
if 192.168.0.2 sends a packet to 192.168.0.3 than it is local and is sent
directly to the computer.
if you send it to 192.168.2.3 than it can't reach it directly and hence
sends it to the gateway. And you rely that the gateway 'knows' what to do
with the packet :)
CV> What are these ?
CV> | | Dlink ROUTER or Hub ?orGateway?
all 3 :))
if you payed more than propably switch, router/gateway
