Question

When TCP/IP translates a network layer address into a data link layer address, it sends a special ____________ to all computers in the subnet.

Answer 1

Answer:

Broadcast message

Explanation:

A broadcast message is a specialized type of message sent to all computers, or other networking devices, on a particular local area network(e.g Ethernet) or subnet. In the TCP/IP protocol, the broadcast message is sent when the network layer address is translated into a data-link layer address.

Examples of a broadcast message transmission are television signals sent from a source network to all viewers around the globe.

In a LAN (local area network), the address resolution protocol uses the concept of broadcast messaging to send an address resolution query to all the networking devices connected to the LAN.

Therefore, in essence, a broadcast message is sent from one source network device to multiple destination networking devices basically on the same network.

Answer 2

Answer:

Broadcast message

Explanation:

The network models like OSI and TCP/IP suites have standard layers and protocols that governs the communication of end devices in a network.

The TCP/IP suite model has four layers which are application, transport, internet and network access layers. The network access does the work of both the data-link and physical layer of the OSI model.

When the packet is encapsulated in a data-link header and trailer, and needs to be sent to another unknown host, a broadcast message is sent to all the computers in the network to retrieve the remote host address for a unicast transmission to take place.
