What does "SYN" stand for in the TCP handshake process?

In the TCP handshake process, "SYN" stands for Synchronization. This term is essential in the establishment of a TCP connection between two devices. When a client wants to initiate a connection with a server, it sends a SYN packet to the server. This packet indicates that the client is requesting to establish a connection and is ready to synchronize sequence numbers, which are important for ensuring that data is transmitted in the correct order.

The SYN flag is used in the first step of the three-way handshake, which is a process that involves sending a SYN packet from the client, followed by a SYN-ACK (synchronize-acknowledge) packet from the server, and finally an ACK (acknowledge) packet from the client to confirm the establishment of the connection. This synchronization step is crucial for setting up a reliable communication channel, as it lays the foundation for further data transmission.

The other options do not accurately reflect the meaning of the "SYN" flag within this context. "Session" does not specifically describe the purpose of this flag, while "Sender" and "Subnet" also do not relate to the TCP handshake process or the significance of synchronization in establishing a connection. Understanding the role of SYN in the connection setup process is vital for
