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.
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.
<h3>ANSWER:The main reason why laptops are more expensive than desktops is in the development costs to create hardware that is compact enough and at the same time meeting an expected level of performance.</h3><h3>And it’s not just performance that is a big challenge. It is also keeping the system cool enough that stability is maintained under most common usage conditions</h3>
5,400 because it turns at the right speed, but if it is too fast or too slow, it will not perform at it's fullest potential. Such as speed and storage.
