Understanding Test About LAN

LAN (local computer network) is an internal computer network, connecting computers in a small range. Modern LAN connected machines can communicate with each other as well as with external computers. But other computers cannot start the opposite. That's because your local area network is designed to be 'private' with the IPv4 standard.
