If you are using Manual Registration, you will need to locate the MAC address of your wireless device.

You must have it on hand to register for the UCInet Mobile Access network and campus-wide DHCP services.

This Web page will help you locate and identify it so you may register your Network Interface Card (or cards) for the network.

Double-click on either Local Area Connection icon (if you are trying to register your Ethernetwired connection) or Wireless Network Connection.

You will have a physical address for each network connection that you have.

An Ethernet data frame contains information that is read out at different levels of the OSI model.

What this is all about and how you can find or rewrite the MAC address is explained below.

This adapter receives a worldwide unique identification number from the manufacturer: the MAC address.

This enables devices like desktop computers, tablets, or mobile phones to be identified in the network and addressed as required.

If a device has several network adapters (for example, for several LAN connections or different communication standards like Ethernet, WiFi, FDDI, Bluetooth, or Token Ring), a different address is available for each standard.

Definition The MAC address (short for media access control address) is the worldwide unique hardware address of a single network adapter.

The physical address is used to identify a device in computer networks.

Since MAC addresses are assigned directly by the hardware manufacturer, they are also referred to as hardware addresses.

With Microsoft Windows, the MAC address is referred to as the physical address.

Apple uses the terms Ethernet ID, Airport ID, or WiFi address, depending on the communication standard.

The term device address, on the other hand, is fuzzy, since a device can have several network adapters and therefore different MAC addresses.

The MAC address in practice Conflicting MAC addresses are a basic requirement for error-free network communication.

Data transmission in computer networks is a complex communication process in which different requirements including reliability, security, and efficiency must be met.

This can be illustrated using the OSI models (abbreviation for open systems interconnection) a reference model developed by the ISO (International Organization for Standardization) that maps network communication to 7 layers.

During data transmission, each layer of the OSI model is run through on both the sender and receiver sides.

MAC addresses are used on the backup layer (layer 2) of the OSI model actually, the media access control sublayer introduced by the Institute of Electrical and Electronics Engineers (IEEE).

Note In the extension of the OSI model designed by the IEEE, the backup layer (layer 2) is divided into the sublayers media access control (2a) and logical link control (2b).

The backup layer is located between the bit transfer layer (layer 1) and the switching layer (layer 3).

While the bit transmission layer provides protocols and tools responsible for maintaining the physical connection, protocols on the backup layer control how different systems share the available transmission medium.

Secure system connections are abstracted from the physical connection.

The actual transmission of data packets takes place at the switching level via IP.

For example, if you want to send an IP packet over Ethernet, your computer transmits a data frame that is addressed to the target computers MAC address on the backup layer, according to the OSI model.

Note If the target computer is not in the local network, a router is addressed and instructed to forward it to the internet.

Routers integrated into a social network also have a unique MAC address.
