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.
A MAC address (physical addresses) is used for distribution of information with in the network segment. The Ethernet uses MAC address to transfer data between hosts. When its used with IP network, the IP address is resolved using ARP protocol to find the MAC address of the end device and the data is transmitted.
