Host 2 will respond to Host 1's SYN message by sending back a SYN-ACK message, indicating that it has received the initial request and is ready to establish a connection. Once Host 1 receives this SYN-ACK, it will complete the three-way handshake by sending an ACK message back to Host 2. This process establishes a reliable TCP session between the two hosts, allowing them to communicate effectively.
There are in total seven layers in OSI model . OSI model layer that is responsible for the termination of connections between hosts is session layer . Session layer is responsible for the dialog control .
broadcast
In the OSI model, the session layer is in charge of coordinating various applications as they are communicating with different hosts. This layer establishes, manages and terminates sessions of the applications accordingly.
broadcast domain
That means the message is sent, not to a single host, but to all hosts on a network. (A host may be a computer, or other communicating device.)
Communication between communicating entities/hosts in a network. Happens in Session Layer (According to the OSI model).
The process which initiates the communication is the client; the process that waits to be contacted is the server.
Sending a thank you note after a presentation is important because it shows appreciation for the opportunity, demonstrates professionalism, and helps to maintain positive relationships with the audience or hosts.
Summons of the Lord of Hosts was written by Baha'u'llah in 1868 as a letter to the world's religious and secular leaders, proclaiming His station as a Manifestation of God and calling on them to recognize His message and contribute to world peace and unity.
The protocol used to send an unknown message back to originating hosts is Internet Control Message Protocol (ICMP). Specifically, ICMP can send messages such as "Destination Unreachable," which informs the sender that a packet could not reach its intended destination. This helps in diagnosing network issues and improving communication reliability.
ICMP The Internet Message Protocol (ICMP) allows hosts to exchange messages to indicate the status of a packet as it travels through the network.
