Question

How does TCP/IP establish and tear down connections?

Answer 1

TCP/IP establishes and tears down connections using a three-way handshake process and the FIN packet for termination.

Step-by-step explanation:

TCP/IP (Transmission Control Protocol/Internet Protocol) establishes and tears down connections using a three-way handshake process.

1. The client sends a synchronize (SYN) packet to the server to initiate the connection.
2. The server responds with a synchronize-acknowledgment (SYN-ACK) packet, indicating its willingness to establish a connection.
3. The client sends an acknowledgment (ACK) packet to the server, confirming the connection establishment.

To tear down the connection, either the client or the server can send a special packet called a FIN (finish) packet. Once both sides have sent and received the FIN packet, the connection is terminated.
