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.

In an IPv4 environment what information is used by the router to forward data packets from one interface of a router to another?
It uses the MAC address, Media Access Control. Every packet sent from a computer contains its MAC address. The router stores this in its routing table. When it receives a packet with a destiation address of that MAC address, then it forwards it to that computer. This is called NAT, Network Address Translation. It uses the Destination IP address
Why is it advisable to enter a next-hop IP address when creating a static route whose exit interface is an Ethernet network?
In a multi-access network, the router cannot determine the next-hop MAC address for the Ethernet frame without a next-hop address.
What is the effect of a router on delimiting broadcast traffic and conserving bandwidth?
Generally speaking, routers will unicast-forward incoming packets which have a network broadcast address as destination, unless they are directly connected to that network/subnet and therefore know that the destination address is a broadcast address
Which two items are used by a host device when performing an ANDing operation to determine if a destination address is on the same local network?
subnet mask destination IP address
Which part of an ip packet does the router use to make routing decisions?
the network portion of the destination ip address
What happens when a node on an Ethernet network is creating a frame and it does not have the destination MAC address?
The node sends out an ARP request with the destination IP address.
What is a private MAC address?
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 is the importance of MAC?
MAC address is a unique number which is necessary for communication between computers in network. It identifies a source and destination device within a Ethernet network.

What is the Mac address used for?
The address for a device as it is identified at the Media Access Control (MAC) layer in the Ethernet networkarchitecture. The MAC address is usually stored in ROM on the network adapter card and is unique.When reaching another host on your own network, or when accessing a router on your network to reach another network, The IP address (4 numbers separate by dots) is converted to the MAC address of the host or router on your network. When the message or packet(S) are sent out, the device with that destination MAC address recognizes that it was meant to receive the message and accepts it. Any other device on the network that can see the transmission is expected to ignore it.An exception is a device or router that is configured to be "promiscuous". Such a machine will also accept and process all transmissions even if meant for another device. This is often used for network monitoring/logging, maintenance, and problem resolution.Although the MAC address is hard coded into the network interface or device, in almost all cases it can be changed. An example for this is when an ethernet network is used with the DECnet protocol. DECnet can be used instead of or togetherwith TCP/IP (or Netware or NetBEUI). The DECnet protocol requires that the MAC address be changed to incorporate the DECnet address as part of the MA address.A MAC address is the serial number of a network card - or other equipment that connects to a network, usually an Ethernet network. In an Ethernet network, the MAC address is used as source and destination address, to know who is communicating with whom. For example, a switch uses the MAC address to forward a frame (a pieces of data) to the correct computer.

What is the importance of Mac addresses?
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, hardware address, adapter address, or physical address.
Which operation is used by a router to extract the destination network address from the destination IP address of a packet?
Route table lookup
Best definition for the network term MAC address?
The MAC address is the serial number of the network card (NIC). It is used in network communication (for example, in Ethernet networks) as a unique identifier for every computer (and other hosts).The MAC address is the serial number of the network card (NIC).

What happens when an Ethernet network node broadcasts a data transmission?
The data is broadcast to all network nodes but only the destination node or nodes respond
What is need of logical to physical address translation?
== == I'm not a vandal or spammer I just haven't created a username and password yet but the answer to the question is that your physical address is burned into the net work card adapter on your PC or on Apple Macs by the manufacturer at the time of production and they are all unique. That physical address, just like your mailing address it is real, is also called your MAC address (Media Access Control address) and looks like this 00-56-7E-4A-DD-8D. The logical address is what the IP (Internet Protocol) address, can also be called virtual address, is and it looks like this 216.109.112.135 and is Yahoo's IP address. Your IP address can change and often does when you have a high speed Internet connection. This is called your DHCP Lease and it actually has an expiration date and time. When it expires you may get the same one or another one depending on what available IP addresses the DHCP server has available. You can also do this with the release and renew commands. You can look up the addresses on your computer with the ipconfig -all command in Windows command line utility (cmd on 2000/XP). To do this go to Start - RUN - type 'cmd'. Then your console window should open up. In there you can type 'ipconfig -all' and you will get the information about your physical address and IP address. To lookup Yahoo's or Google's address type ' nslookup yahoo.com or nslookup google.com and you should get the corresponding IP address of the web site. nslookup (name server lookup) is a network command line utility that will display the IP address of a site. I hope this helps as there is a great deal more information that I could write about these two address types.
What can be identified by the network layer header?
destination host address
