You can't really change the MAC address of a NIC, there is a way to do it through filtering but i dont recommend it, better to use a router or get a new NIC
But if you really want to and have Windows 2000/XP
# o to Start->Settings->Control Panel and double click on Network and Dial-up Connections. # Right click on the NIC you want to change the MAC address and click on properties. # Under "General" tab, click on the "Configure" button # Click on "Advanced" tab # Under "Property section", you should see an item called "Network Address" or "Locally Administered Address", click on it. # On the right side, under "Value", type in the New MAC address you want to assign to your NIC. Usually this value is entered without the "-" between the MAC address numbers. # Goto command prompt and type in "ipconfig /all" or "net config rdr" to verify the changes. If the changes are not materialized, then use the second method. # If successful, reboot your systems.
Doesn't matter if your connected to a LAN or not. The MAC address is hard coded into the NIC and does not change unless software on the computer requires that it changes.
Under normal circumstances: No. The MAC address is hardcoded in the network controller (NIC), e.g. on a Flash chip. If the computer uses a non virtual NIC (as used on virtual machines) and there are no drivers installed that change the MAC inside the operating system, the MAC stays the same. But drivers/configurations can overcome the static MAC using the OS behavior. In most cases the MAC isn't read by the OS every time it is used, its rather stored somewhere. If that "somewhere" was changed, the MAC will certainly change if the computer is formated. Same applies if the computer uses virtual NICs. If you know the MAC and it is not the same as hardcoded in the NIC, you can restore the MAC after reinstallation.
MAC address stored in NIC card
•What is the physical address (the MAC address) of the NIC (or network adapter) for this connection?
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.

MAC bit size is 16 digits. but MAC bit is 48 each.

no we cant have two mac unless we have two nic's
In general, the MAC address is tied to a specific piece of hardware and does not change. It is possible, however, under certain circumstances to change the MAC address. MAC addresses are most often assigned by the manufacturer of a network interface card (NIC) and are stored in its hardware, the card's read-only memory, or some other firmware mechanism. If assigned by the manufacturer, a MAC address usually encodes the manufacturer's registered identification number and may be referred to as the burned-in address. It may also be known as an Ethernet hardware address (EHA), hardware address or physical address. Although intended to be a permanent and globally unique identification, it is possible to change the MAC address on most modern hardware. Changing MAC addresses is necessary in network virtualization. In this case, the MAC address of the actual NIC is hidden from the network and the network only sees the MAC assigned to the virtual NIC - which can be configured, with some finesse, to be dynamic. It can also be used in the process of exploiting security vulnerabilities. This is called MAC spoofing.
Type your answer here... yes, we can connect a nic to a nic. A nic is a Network Interface Card which has a unique MAC. When we connect two devices(say laptops) using a lan cable,we actually connect their nics.
