Can two computers have the same MAC address?
NO, its not possible to have same MAC addresses for two different network cards. because MAC address is a unique part of the recognition of the network card and it is also called as PHYSICAL address of your PC. There is possibility of 2 network cards with same MAC address by 3rd party MAC spoofing techniques.........
Which category of adapters includes NICs?
Communications
What must match in the communications between all NICs on a network?
The subnet mask must match for all NICs in a LAN, otherwise the packets must be forwarded to another network via a router.
Port used for external wireless NICs?
Typically USB ports are used
What is different limited broadcast and directed broadcast?
Limited Broadcast - Sent to all NICs on the some network segment as the source NIC. It is represented with the 255.255.255.255 TCP/IP address. This broadcast is not forwarded by routers so will only appear on one network segment.Direct broadcast - Sent to all hosts on a network. Routers may be configured to forward directed broadcasts on large networks. For network 192.168.0.0, the broadcast is 192.168.255.255.
What is the purpose of media access control?
Media Access Control address (MAC address) is a unique identifier assigned to most network adapters or network interface cards (NICs) by the manufacturer for identification.
What is used as a unique NIC identifier?
A Media Access Control (MAC) address is used as a unique identifier for network interface cards (NICs). Each device connected to a network has a unique MAC address assigned by the manufacturer.
Characteristics of a Mac address?
Media Access Control address (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.
Why there are 48 bits in Mac?
MAC address is the Layer 2 based unique address assigned (burned) to Network Interface Card. Out of 48 bits First 24 bits are assigned to Manufacturers (Of NIC Cards) & other 24 bits are assigned to each NIC by Manufacturer. 48 bits in MAC address provides unexhaustive possibility in near time for manufacturing NICs with unique identity number.
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.
How can you identify your computer from the internet What naming conventions were given to organization for proper organization?
One way is by the (MAC address). It is a unique identifier assigned to most network adapters or network interface cards (NICs) by the manufacturer for identification.
How is it possible for two network cards to work on the same computer?
That's an easy one! Each Network Interface Card (NIC) has its own machine level address, called a MAC address which is assigned and programmed into it during manufacture. This is different from the IP address, which can be changed. A NIC is a special hardware card that handles the sending and receiving data computer network. The address that identifies a NIC is called the Media Access Control (MAC) address. A MAC address identifies a specific physical device and never changes for the life of the NIC. Two NICs never have the same MAC address (unless some manufacturer screws up royally [which has happened]). Because your NIC's MAC address is permanent, it's often referred to as the "real," or physical, address of a computer. Two get two cards working just install them and their drivers. If they are both identical, they can use the same driver set.
Which componets operate at the physical layer?
The network interface cards (NICs) connectors cables
Which two layers of the OSI model do NICs belong?
Primarily in the Physical (first) layer to be the transciever for the Line, but many cards these days also have acceleration and cache MAC-IP addresses and and speed up ARP requests and translation to IP Addresses which are at the Link (second) Level.
What are the devices that work on physical layer?
1) Physical layer is the first layer. 2) The simplest ones operate at the physical layer are: Repeaters, conventional hubs and transceivers. 3)These devices have absolutely no knowledge of the contents of a message. They just take input bits and send them as output. Cheers, AceInfo Solutions.

Can old NICs mix with new high speed NICs?
Usually yes. It will always operate at the speed of the slowest device.
