Q: What are the three steps of the TCP three-way handshake?

A: The three steps are:

1. The client sends a connection request (SYN) packet to the server, which includes the client's Initial Sequence Number (ISN).
2. The server responds with a SYN-ACK packet, which acknowledges the client's request and includes the server's own ISN.
3. The client sends an ACK packet back to the server, confirming the connection is established.
