What is the broadcasting operation?

In the computer network, transmitting operation is a type of data sent to all computers and devices on a network or subnet. It is used in situations where all possible network destinations need to be achieved or when the address of a particular computer is not known. A large amount of broadcasting can slow down or unfit networks, and some hackers used it to flood the network with unnecessary data. Most network traffic falls into one of two categories: Unicast Traffic, which is intended for one computer or multi -way operation addressed to multiple destinations. Transmitting operation is the more unusual type of network traffic that is sent to all computers and devices in the network or part of the network. It is handed over to a special broadcast address that all computers in a specific network or subnet. This type of operation can take place in a network layer independent of hardware or in a layer of physical connection focused on hardware and allows a computer to achieve every single -message target.

Compared to Unicast operation and multi -way broadcasting, transmission creates a larger volume of data packets flowing through the network at once. As a result, broadcast messages are generally limited to just a few applications where it is important to reach all computers or devices on the network. Some examples include files or print servers announcing the availability of their resources, routers looking for additional routers around or more efficient network paths, or computers translating addresses of physical connection to the Internet protocol address (IP) used in the network layer.

Transmitting can also be very useful in situations where a specific computer needs to be achieved, but its address is unknown. One very common network protocol that uses transmission in this way is the dynamic host configuration protocol (DHCP), which allows you to automatically load the network settings from the server. When a computer is using tThe ENTO protocol connected to the new network, sends the "DHCP Discover" message that asks the DHCP server to identify and provide network information.

Each machine in the network must receive and process the operation of broadcasting, so incorrect or malicious application can adversely affect network performance. The operation of broadcasting can also be used to attack the rejection of services designed to flood the target network with nonsensical data and make it unavailable legitimate communication. One such attack, known as broadcasting or "smurfing", uses requests for ping sent to a transmitted address from a spoofed address to create the effect of a snowball of responses and error responses. Most routers now have guarantees for protection against this vulnerability, but a poorly configured network can still be endangered.
