MAC address
ifconfig <if device> inet <ip address>
Because without an IP address a device cannot communicate on a network. Within a LAN, an IP address must be unique.
It's false. Any networking device like a computer that is connected to a LAN has both a hardware address and an IP address.
Any device on a LAN is called a node.
When an ISP provides internet service, it provides one publicly routed IP address. Assigning a private IP address to each device in the home or office prevents one device from interfering with Internet access of other devices on the LAN. It also provides greater security for each device. Public address space is conserved

A Switch looks at the MAC address its a layer 2 device (OSI Model).
A broadcast packet is sent and received by all systems on a LAN; it can contain any kind of data. The more broadcasting that a LAN does, the slower it will be overall since every device has to read the packet.
ARP is a protocol that maps MAC addresses to IP addresses for packet delivery and for finding out which device in a LAN has a given IP address.
You have installed a device that has two IP addresses. One address, 64.51.216.27, is displayed to the Internet. The other address, 192.168.50.254, communicates with the LAN. What type of technology have you implemented?
