If the destination mac is not on the arp table of the switch then that arp request from the transmitting port is redirected to the router, to see if the device is available outside of the network.
my understanding was that the switch when powered up sends out a ARP request to all ports to find out what macs are sitting on what port and then once the devices reply with the MAC addresses. the switch populates its ARP Table with mac and ip addresses. So when a machine wishes to send data to a machine on the local network, the switch will look up the machine on its ARP table and redirect the traffic so the two machines can initiate a handshake and prepare for data transfer.
Common dude, why you are not explaining how switch actually works? Show them how switch get to know the destination MAC address using ARP and how the first PC will know the MAC address of the destination device. Tell them that ARP request is broadcast and ARP reply is unicast. IF ANYONE OF YOU NEED TO DISCUSS SWITCHING WITH ME, ADD me on Skype. My ID is "MBilalBhatti"
Heres the thing, im at university and my room has ethernet to access the internet. It requires installation of a CD and providing admin with my computers MAC address to access the accommodation's network. I also want to use Xbox live but the disk cannot be installed onto there, would I be able to use this switch to access xbox live directly from my laptops internet connection (which is plugged into the wall using ethernet)?
@Tubekid200 it is possible, however, you will need a second network card. get a usb or pcmcia network card depending on the age of you laptop. next share or bridge the network card connected to uni internet to the second nic. you can use ICS (internet connection sharing) in windows 98, xp,vista, 7. or even install a proxy type software. connect your xbox to the second nic on the laptop. you need to configure ICS so that dhcp is enabled for the xbox to get a ip address from the second nic.
Won't every computer access the internet, if you have a wired router? and you wire it to all the computers? I just bought a desktop switch by netgear today, and I don't know if it is the same as a router or better. My questions:
1.) Will it let me connect to the internet with multiple computers at the same time?
2.) Will I be able to connect my modem to the switch, and the computers to it
3.) What is the difference between in and a router
I'm not exactly sure which netgear model you bought, but...
if you bought a netgear router/switch combo that had 1 router port with 4 built in switch ports then yes you could connect multiple computers to the internet at the same time. You would plug your modem into the router port and your computers into the switch ports.
@john55223 know that is just a switch. You could buy something like this: Cisco Linksys - E1200 Wireless-N Router with 4-Port Ethernet Switch. It has wireless too.
Sometimes cable/dsl modems come with routers built in. So, before you buy something else I would check.
if I have a router, connected to a switch... And the switch then has around 3 computers connected to it, can they all access the internet at the same time? Someone told me they couldn't, I'm confused:(
They can, the person who told obviously doesn't know what they are talking about. A switch doesn't mean that you 'switch' between computers, it is just like a hub, but more efficient.
Sometimes I get to smart for my own good and refer back to the basics. Your awesome to dumb it down for me, but you bring back to light the way I learned it in the first place. Thanks.
Continued from previous comment... And what is this crap at the end talking about a Point to Point connection, and that no one else can communicate? HAHAHA a point to point connection is something COMPLETELY different. Point to Point connections are used when talking about routing... for example: you would use a point to point connection to connect two offices together. this could be a leased T1 or T3 line.
Im soo sorry to say this but you have NO idea what your talking about... Assuming you just turned on these computers, the FIRST thing PC1 is going to do is send an ARP request. This is because PC1 dosen't know PC2's MAC. Once PC2 has replied with it's MAC address, PC1 can now transmit the frame out onto the network. Continued on next comment....
Heres my question I have a internet coming into a cable modem then to a switch then to pc#1. From the next empty port in the switch i run a chord to pc#2. Do i need a diffetent IP adress for every PC to connect to the internet from that switch? Is a switch used for sharing data because most switches cant assign IP adresses right?Only routers can do that right?
i got some questions, first some things i need to comfirm =)
hmm i jsut bought a switch and i cant get it to chare the network to more than 1 computer, how can i make it to share the network so many computers can go on internet at the same time?

Sorry, but on Layer 2 units, such as Cisco - Frames are not supported; that's a Layer 3 responsibility.
