Multicast,broadcast and unicast are Data transmission methods
The multicast transmission:
It is a transmission method in which data is sent from a server to specific nodes that are predefined as members of a multicast
group. Network nodes not in the group ignore the data. Communication with nodes outside of a multicast group must be done through unicast or broadcast transmissions.
It is a transmission method in which data is sent from a source node to all other nodes on a network.
Network services that rely on broadcast transmissions generate a great deal of traffic.
Occasionally, nodes use broadcast transmissions to check for the availability of a particular service on the network.
If the service is not available, the nodes broadcast a request for the service. If a server is present, it responds to the request.
It is a method for data transfer from a source address to a destination address. Network nodes not involved in the transfer ignore
the transmission. Unicast transmission is the predominant mode of transmission on LANs and the Internet. Some familiar unicast
applications are Hyper-Text Transfer Protocol (HTTP), Simple Mail Transfer Protocol (SMTP), and File Transfer Protocol (FTP).
The wireless LAN(WLAN) adhere to the IEEE 802.11 standard, where the Access Points(AP) are used to provide a hot spot for wireless clients in the vivinity. It operates as a hub-and-spoke topology
The point “H” is the wireless Access Point and from the A to F are the stations.
The wireless networks are shared and use Carrier Sense Multiple Access/Collision Avoid(CSMA/CA). Do you want to test or prepare the Comptia network+
