Question

Accepted Answer

The 3-way handshake is a method used in TCP/IP networks to establish a reliable connection between a client and server.

Step 1: SYN - The client sends a SYN (synchronize) packet to the server to initiate a connection.
Step 2: SYN-ACK - The server responds with a SYN-ACK (synchronize-acknowledge) packet to acknowledge the receipt of the SYN.
Step 3: ACK - The client sends an ACK (acknowledge) packet back to the server, completing the handshake.
