MAC addresses are primarily assigned by device manufacturers, and are therefore often referred to as the burned-in address, or as an Ethernet hardware address, hardware address, or physical address. Each address can be stored in the interface hardware, such as its read-only memory , or by a firmware mechanism.
MAC address anonymization performs a one-way function on a MAC address so that the result may be used in tracking systems for reporting and the general public, while making it nearly impossible to obtain the original MAC address from the result.
In computer networking, MAC address filtering is a network access control method whereby the MAC address assigned to each network interface controller is used to determine access to the network. MAC addresses are uniquely assigned to each card, so using MAC filtering on a network permits and denies network access to specific devices through the ...

The MAC address that is hard-coded on a network interface controller (NIC) cannot be changed. However, many drivers allow the MAC address to be changed. Additionally, there are tools which can make an operating system believe that the NIC has the MAC address of a user's choosing. The process of masking a MAC address is known as MAC spoofing.
What became the iMac began as Apple's effort to develop the consumer desktop to fill that product gap. [citation needed] Apple's head of design Jony Ive and the rest of the design team developed sketches for a distinctive, all-in-one computer that was to be a legacy-free PC focused on ease of use and internet connectivity. The design team made ...
