  Re: what is the difference between switch and router??
Answer
# 1
1.Switch are said to be l2 device only but Router are said 
to be L3 device.
2.Switch is said to be H/W Device.Router are said to be S/W 
device.
3.Switch perform faster than the router because it is a H/W 
Device.

Switch are basically layer2 device and it works on Hardware
technology with map the mac addresses and it works with
switch table.

Router is known as layer3 device and works alos on hardware
technology and map the mac addresses. it basically connects
two different networks or netids to each other.it works with
routing table.

1] Switch is separate collision domain. single broad cast
domain. this breakup collision domain.
   Router breakup broadcast domain.

2] Switch hardware oriented. L2 devices. packet transferred
through mac address
   Router Software oriented. L3 devices. packet transferred
through ip address

3] Switch connected between same network
   Router connected between different network.

to be L3 device.
2.Switch is said to be H/W Device.Router are said to be S/W 
device.
3.Switch perform faster than the router in lan.
4.Switches used in LAN in small org.Router are used in WAN
5.We have l3 switches but it will not have all functions 
like Router.

Answer
# 5
1] Switch is singe broadcast and mutiple collision 
device.i.e switch breack the collision domain
   Router is mutliple collision and mutiple broadcast 
domain..breakup broadcast domain.

2] Switch hardware oriented. L2 devices. packet transferred
through mac address..working at layer 2 of OSI model
   Router Software oriented. L3 devices. packet transferred
through ip address..working at layer 3 of OSI model.

3] Switch extand the same network
   Router connected between different network.

Answer
# 6
switch is l2             router is l3
switch segment c.d.      router segment b.d
works on frame (mac)     works on packet (ip)
perform switching        perform routing & switching
works on h/w asics (slow )   works on s/w(slow)

1)switch is considered to be an intellengent device because 
there is rare chance of collsion 
                  1)router is an important device because 
it work in network layer third layer of the open system 
interconnection layer
2)switch works on data link layer of the osi reference 
layer,it works depond on mac address(media access control)
                  2)router is used to communicate two or 
more different network
3)when a switch is connected to the host each time it send 
a broadcast ip address and mac address
                   router is consider to be a software 
device  
4) but swich is considered to be a hardware device because 
it uses a special chip call asic(application specific 
integrated circuit)

Of the following switching types, which one has the highest latency? A.) Cut-through B.) None C.) Store-and-forward D.) Fragment Free  1
How does the cut-through switching technique work? A.) By using broadcast address as source addresses B.) The switch waits only for the header to be received before it checks the destination address and starts forwarding the packets C.) The LAN switch copies the entire frame into its onboard buffers and then looks up the destination address in its forwarding, or switching, table and determines the outgoing interface D.) By using a Class I repeater in a collision domain  1
