Since each indifference curve represents a different level of satisfaction, indifference curves can never interÂ­sect at any point. The same reasoning applies if two indifference curves touch each other at point Ñ in Panel (B) of the figure. (6) An indifference curve cannot touch either axis.
A media access control address (MAC address), also called physical address, is a unique identifier assigned to network interfaces for communications on the physical network segment. MAC addresses are used as a network address for most IEEE 802 network technologies, including Ethernet and WiFi. Logically, MAC addresses are used in the media access control protocol sublayer of the OSI reference model.
The MAC address is most frequently represented as 12 hexadecimal digits. The MAC address uniquely identifies a specific network device and MAC addresses must be unique on a given LAN (a network of computing devices in a single subnet of IP addresses). The first 12-bit portion of the MAC address identifies the vendor of the network device, the last 12-bit portion
