Answer: Mesh
Explanation:
Mesh networking topology is one of the type of local networking topology where the nodes are directly connected dynamically in the mesh infrastructure.
The routing and the flooding are the techniques that is typically used the mesh topology and it is one of the most effective type of networking communication.
According to the given question, the Zigbe and the Z-wave are used the networking topology for facilitating the communication and it is commonly using in the various types of wireless networking.
Therefore, Mesh networking is the correct answer.
Answer: False
Explanation:
Unguided medium employs an antenna for transmitting through air or vacuum.
For guided mediums the transmission is in the form of twisted copper wires, shielded twisted copper wire and optical fibres. They henceforth do not depend upon antennas for transmission through air using antennas.
