What will a host on an Ethernet network do if it receives a frame with a destination MAC address that does not match its own MAC address?
On a hub network:The host (PC-A) computer sends the frame out its Network Interface Card (NIC) to Fast-Ethernet 0/1 (F0/1) on the HUB. The HUB then sends that frame out every interface (except incoming interface). If the destination MAC address is aaa.bbb.ccc, and PC-B has MAC address aaa.aaa.bbb, then PC-B's NIC will ignore the frame and nothing else will happen.
What is the physical address (the MAC address) of the NIC (or network adapter) for this connection?

What security advantage occurs from Packaet's containing the source NIC address and not just the destination NIC address?
The message must travel from your computer to your router. Every computer connected to a network has a network interface card (NIC) with a unique physical address, called a MAC address (for Media Access Control). At the data link level, two more headers are added, one for your computer's NIC address (the source MAC) and one for your router's NIC address. A data link layer structure with destination MAC, source MAC, and data is called a frame. Every NIC selects from the network those frames with its own address as a destination address. The data link layer adds the structure necessary for data to get from your computer to another computer (a router is just a dedicated computer) on your network. Data Link Layer Transformation.
The physical address is a fixed number associated with a device's nic it is initially assigned at the factory and stored in the nic's on-board memory you can find a nic's mac address through your co?
if by co you mean computer then yes you go to command prompt and type in "ipconfig/all" and you go to "network interface(or whatever it calls your nic)" and it will show u the physical address of your nic
What is the difference between hardware address and IPv4 address?
The hardware address or MAC address is encoded on the NIC by the manufacturer for unique identification of the NIC. This cannot be changed.... The IPv4 address is an internet address usually assigned by a DHCP server for each computer on a network. This address can be changed.
Which address does an NIC use when deciding whether to accept a frame?
Destination MAC address
How does the NIC of a receiving PC use the destination MAC address?
The receiving NIC must check that the destination MAC of a frame is the same as the MAC of the receiving NIC. If it isn't, the NIC isn't the intended destination, and it will just ignore the frame (unless it is set to "promiscuous mode", in which case it will accept all frames).The receiving NIC must check that the destination MAC of a frame is the same as the MAC of the receiving NIC.

What is the the purpose of the preamble in an Ethernet frame?
It gives the receiving NIC time to realize a frame is coming and to know when the frame starts..
