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.
It is the 12 hexadecimal digit combination identifying the manufacturer and id of your NIC the first 6 digits is the OUI(Organizationally unique Identifier), this identifies the company that made the NIC the last 6 digits is the USI(Unique station identifier) this identifies your NIC A NIC identifier can only contain letters from A to F and numbers from 0 to 5 a NIC identifier, more commonly known as data-link layer address or MAC address looks like this: A6-D5-FF-5A-3D-6A
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).

a unique item identifier means what?
In a standard MAC address, the first 24 bits are assigned by the manufacturer and are known as the Organizationally Unique Identifier (OUI). This unique identifier is used to identify the manufacturer of the network interface card (NIC). The remaining 24 bits are assigned by the manufacturer to uniquely identify the device within their range of addresses.
The built-in identifying address coded into a Network Interface Card (NIC) is called a MAC address. It is a unique identifier assigned to the hardware by the manufacturer and is used to identify devices on a network. MAC addresses are typically 48 bits long and are displayed in hexadecimal format.
The Vendor ID (OUI) of the Sources NIC is the unique organizational identifier assigned to the manufacturer of the network interface card by the IEEE. The OUI is the first three bytes of the MAC address assigned to that device.
It is used as the unique identifier for each record and is used to sort the data
The NIC serial number is a unique identifier assigned to a Network Interface Controller (NIC) and can typically be found on the device itself, in the device's settings, or through system information tools. To locate it, you can check the NIC's documentation, the manufacturer's website, or use command line tools like "ipconfig" on Windows or "ifconfig" on Linux. If you need help finding a specific NIC's serial number, please provide more details about the device.

An attribute used as a unique identifier but not qualifying for it. A good example would be "Name" attribute in "Kid" entity - it's not unique, there can be other kids with the same name. I hope that helped anyone.
An ISBN is a unique identifier for books, while a DOI is a unique identifier for digital documents and research articles.
