Uh... I don't think that all Macs have the same one. But, if they do, it probably either: A. Has Apple mentioned or:
B. Has Mac mentioned.
A MAC address is unique to your ethernet card. MAC addresses are used within an Ethernet network to uniquely identify the source and destination of Ethernet frames. ARP (Address Resolution Protocol) is used on IP networks to map IP addresses to MAC addresses within an Ethernet network.
What are two primary responsibilities of the Ethernet MAC sublayer? (Choose two.)
what are the ethernet frame parts The source and destination MAC addresses
One computer must have unique MAC addresses for each Ethernet adapter (ideally each Ethernet adapter in existence has a unique MAC address but there are some that allow manual setting of the MAC, so duplicates can exist.) If you have not changed anything from the factory settings then each network card will have a unique address!
The Mac Pro has two Ethernet ports so that two Ethernet cables can be connected to the computer. The cables may be connecting a local network or peripheral devices such as printers or cameras that require an Ethernet connection.
You don't "Get" one, because you already have one. A MAC Address uniquely identifies your computer's network interface card on the network. If you're asking how do you know what your MAC address is:Windows:Start>Run>type "cmd"in the black window that appears type "ipconfig /all"the MAC address will be listed as "Physical Address" and usually starts with 00-In Mac OS X 10.5 and later, in the left column of the Network preference window that opens, click the name of your connection (e.g., AirPort, Ethernet, Built-in Ethernet). Click the Advanced... button, and in the sheet that drops down, click either the Ethernet or AirPort tab. The string of letters and numbers next to "Ethernet ID:" or "AirPort ID:" is your MAC address.In Mac OS X 10.3 or 10.4, in the Network preference window that opens, make sure the pull-down menu next to "Show:" lists your connection (e.g., AirPort, Built-in Ethernet). Under the Ethernet or AirPort tab, the string of letters and numbers next to "Ethernet ID:" or "AirPort ID" is your MAC address.Alternatively, you could use "ifconfig -a"Linux:Open a shell, use "ifconfig -a". This will display your current network settings for each interface available on your computer.An example of what a MAC address would look like:00-FF-20-58-C9-60*NOTE* all devices that access the internet have a MAC address (iPhone, PS3, PSP, Switches, Firewalls, Routers, cable modems, cell phones, etc)Wikipedia:In computer networking, a Media Access Control address(MAC address) is a unique identifier assigned to most network adapters or network interface cards (NICs) by the manufacturer for identification, and used in the Media Access Control protocol sub-layer. If assigned by the manufacturer, a MAC address usually encodes the manufacturer's registered identification number. It may also be known as an Ethernet Hardware Address (EHA), hardware address, adapter address, or physical address.http://en.wikipedia.org/wiki/Mac_address
On a Mac, as on everything else, PPPoE is used to configure Point to Point Protocols over Ethernet which allows communication between computers connected on an Ethernet network.
MAC ID is like a serial nr of your network card. On a windows system you can know what you're mac id is through START > RUN > type "cmd" without the quotes > type "ipconfig /all" without the quotes. In the list you'll see the MAC ID is listed (sometimes it's called Physical Address instead of MAC ID). For each network card in your computer (usually only 1) there exists a MAC ID.
The Media Access Control (MAC) address is a number that identifies a computer connected to a network. To find the MAC address on an Apple Mac select About This Mac in the Apple menu (top left), then click on More Info and then on Network in the left hand pane. The MAC address will be listed under Ethernet in the lower right hand pane.
Use the Wi-Fi
The Ethernet protocol's header includes the source MAC address.
no but both a Windows and PC and a Mac can share their Internet connection. If the G4 does not have a wireless Airport connection then the Ethernet cable can be used. (See links below)
