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 Media Access Control address is used to uniquely identify a single piece of equipment. MAC addresses are vital in ensuring equipment can connect to, and network and communicate with, other devices.ach piece of hardware is given a MAC address that is not supposed to change over its lifetime. When a device is connected to a network, its IP and MAC addresses are recorded in an Address Resolution Protocol (ARP) table.
