MAC address


Media Access Control address = A hardware address in the Data Link Control (DLC) layer of the OSI model that translate to the Adress Resolution Protocol (ARP).

You might want to get a book on networking if you want to fully understand your question...Read upon the 7 OSI Network Layers and IEEE 802 standard.
 
Good gawd. I think I will get a book! Sure was a high tech response for someone calling themselves lowtech! You sound like you really know your shiz-nit. The reason I ask is that I've come to understand that multiple computers with the same MAC address on a network is a no-no. Last question then I'll go away and find a nice thick book: How does this affect a simple home network of 3 computers linked together with a router? Network is for file/printer sharing and gaming.
 
Permanent, unique,hardware address of any network device. Some Cable/DSL routers can fake it in order to get connected (if your ISP bind MAC address as user verification. Every vendor has its own range of addresses
 
I don't really know all that much, but my job requires me to do so.

On with the home network?

Get a 4 ports Router if you want to get all computers onto the Internet, otherwise a cheap hub or switch would do.

Uses straight trough cables to hook the computers to the Router internal ports (can use the up-link port with a cross over cable if it is not a share port).

Internal address could be 192.168.x.x or 10.10.x.x

Use a straight through cable between the DSL/Cable modem & external Router port.

Register the router MAC address with your Internet Service Provider (ISP), or clone it from one of you computer.
 
Just to put your mind at ease, having multiple MAC addresses is possible (technically) but not really. Some OLD OLD OLD OLD network cards would let you or force you to set a MAC address manually, but not anymore. Half of the MAC address is unique to the manufacturer, so you won't get conflicts.
 
My prefered book for learning plenty about networking is Andrew Tanenbaum's Computer Networks. It can be a daunting read, but it covers networking better than anything else I've looked through.
