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.
CAM stands for Content Addressable Memory. It is a type of table where fixed-length addresses are kept for fast lookups. Since MAC addresses are fixed length, CAM tables are used to store MAC addresses and their related information. For most purposes, you can think of them as the same thing called by different names.
