What are the three types dyadic communication?
Dyadic communication is the communication between two persons who interact face to face as senders and receivers. Even telephone conversations come under this type, where two people have a conversation. We can say there are two types of dyadic communications, they are, formal and informal. Formal dyadic communications are serious conversations between family and friends, interviews, confessions or counseling. Informal dyadic communications are chatting between friends and family or lighthearted joking. It is impossible not to communicate, and it is important to remember that not all communication within the dyad is verbal. It is often true that much of our communication is non-verbal. Body language, posture, tone of voice, and facial expressions must also be considered when interpreting messages in dyadic communication or in any other type of communication.
What is the difference between Man in the Middle attack and a replay attack?
Man-In-The-Middle: An attack in which communications between two hosts are routed through the attacker's host. The attacker can observe, modify, and/or block selected traffic before relaying to the intended host. Communications between the target hosts appear normal.Replay: An attack in which a copy of communications between two hosts is obtained by the attacker. The attacker retransmits selected portions of the copied communications at a later time for nefarious purposes such as creating duplicate transactions, circumventing authentication, etc.diffrent: a replay attack is a more specific type of man-in-the-middle attack. I view the biggest difference in the intent. In the man-in-the-middle attack the intent is simply to capture the data, but in a replay attack the intent is to reuse the data in an an attack.
Using OSI reference model explain the data communication between two hosts?

How many hubs can exist between two communicating hosts in an Ethernet hub-based network?
You can have a maximum of four hubs between any two hosts (or from a host to the next switch).
Is network protocol needed between two hosts?
A network layer is not needed if both the hosts are in the same network. A data link layer can be used in such cases.
What Coordinates and maintains communications between two nodes on the network?
Session Layer.
What is point-to-point transmission?

Dedicated
