Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDFThe correct answer is Connect.
Key Points
- The connect system call is responsible for establishing a connection to a remote host.
- When the connect system call is executed, it initiates the process of setting up a TCP connection.
- As part of this process, the client sends a SYN (synchronize) packet to the server.
- The server responds with a SYN-ACK (synchronize-acknowledge) packet if it is ready to accept the connection.
- The client then sends an ACK (acknowledge) packet, completing the three-way handshake and establishing the connection.
- The other system calls mentioned (Socket, Bind, Listen) are involved in different stages of socket programming but do not directly result in sending SYN packets.
- Socket: Creates a new socket.
- Bind: Associates a socket with a local address and port.
- Listen: Prepares the socket to accept incoming connections.
Additional Information
- The three-way handshake is a fundamental process in establishing a reliable TCP connection.
- Understanding the role of each system call in network programming is essential for developing network applications.
- Proper handling of socket connections ensures the robustness and security of network communication.
