This article will introduce what IP network transmission types are.
The IP network data transmission has three types: unicast, multicast and broadcast.
Next, I will introduce the definition of the three types.

Unicast transmission: A point-to-point network connection is implemented between the sender and each reciever.
If a sender transmits the same data to multiple receivers at the same time, multiple copy of the same data packet must be copied accordingly. If a large number of hosts want to obtain the same copy of the data packet, as a result, the burden of the sender is heavy, the delay will become longer, and the network will be congested. To ensure service quality, hardware and bandwidth need to be added.

Multicast transmission: A point-to-multipoint network connection is implemented between the sender and each receiver.
If a sender transmits the same data to multiple receivers at the same time, only one copy of the same data packet needs to be copied. It improves the efficiency of data transmissio and reduces the possibility of congestion on the backbone network.

Broadcast transmission: Indicates that data packets are broadcast in the IP subnet. All hosts in the subnet will receive these packets.
Broadcast means
that the network delivers a data packet to each host on the subnet, regardless of whether the host is willing to receive the
packet. Therefore, the broadcast range is very small and is valid only in the
local subnet. The broadcast transmission is controlled by the router and the
switch network device.![]()
So much for today, hope you can learn the differences now!
