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.
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.
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.
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)
