How many bits are in an ethernet mac address
WebMAC address is the physical address, which uniquely identifies each device on a given network. To make communication between two networked devices, we need two addresses: IP address and MAC address. It is assigned to the NIC (Network Interface card) of each device that can be connected to the internet. WebEthernet packets with less than the minimum 64 bytes for an Ethernet packet (header + user data + FCS) are padded to 64 bytes, which means that if there's less than 64- (14+4) = 46 bytes of user data, extra padding data is added to the packet. Beware: the minimum Ethernet packet size is commonly mentioned at 64 bytes, which is including the FCS.
