How many steps occur in the TCP handshake process?

The correct answer is B. three.

The TCP handshake process, also known as the three-way handshake, involves three steps:

1. SYN: The client sends a synchronization (SYN) packet to the server to initiate a connection.
2. SYN-ACK: The server responds with a synchronization acknowledgment (SYN-ACK) packet back to the client.
3. ACK: Finally, the client sends an acknowledgment (ACK) packet to the server, completing the handshake and establishing the connection.

This process ensures that both parties are ready for communication before any data is transmitted. If you have more questions or need further clarification, feel free to ask!
