yes i think, because the MAC address is the physical address which is assigned by the vendor of the Ethernet card. ** Improved Answer ** No, Unmanaged switches do not have a MAC address. All they do is filter, forward or flood frames.
No. Hubs simply repeat all the Ethernet frames on all ports and do not interfere with the source or destination MAC addresses and as such do not need their 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.

The UAA, or Universally Administered Address, is the most commonly used type of MAC address. This address is assigned to the network adapter when it is manufactured. The first three octets define the manufacturer, while the second three octets vary and identify the individual adapter. All network adapter manufacturers have their own code, called the Organizationally Unique Identifier (OUI).
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.
No. The switch itself will only have one MAC address. Only routers use different MAC addresses for each port.

Any network card has its own MAC address, so it doesn't require an extraordinary effort to have your own MAC address. The MAC address is the serial number of the network card.Any network card has its own MAC address, so it doesn't require an extraordinary effort to have your own MAC address.

The MAC address is the LAN/Ethernet card address there is no specfic Mac address for active directoy. Each server/PC in the world has its own unique mac address.
When you connect your computer to a switch, it will automatically detect your computer's settings and will also gather system information, part of this information collected is your MAC address. Every network interface card (NIC) has it's own unique MAC address, and most computers these days have NIC's already installed.
Source or Destination MAC address
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.

Media Access Control (MAC) address filtering is a little different from WEP or WPA. It doesn't use a password to authenticate users - it uses a computer's physical hardware. Each computer has its own unique MAC address. MAC address filtering allows only machines with specific MAC address access the network. You must specify which addresses are allowed when you set up your router. This method is very secure, but if you buy a new computer or if visitors to your home want to use your network, you'll need to add the new machines' MAC addresses to the list of approved addresses.

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.
