THREE-WAY HANDSHAKE or a TCP 3-way handshake is a process which is used in a TCP/IP network to make a connection between the server and client. It is a three-step process that requires both the client and server to exchange synchronization and acknowledgment packets before the real data communication process starts.
What is IP TCP and UDP?
TCP/IP is a large family of protocols that is named after its two most important members. User Datagram Protocol (UDP) UDP is also a transport-layer protocol and is an alternative to TCP. It provides an unreliable datagram connection between applications.
What is TCP FIN?
The FIN flag indicates the end of data transmission to finish a TCP connection. Their purposes are mutually exclusive. A TCP header with the SYN and FIN flags set is anomalous TCP behavior, causing various responses from the recipient, depending on the OS.

What is TCP SYN packet?

How TCP connection is closed?
The standard way to close TCP sessions is to send a FIN packet, then wait for a FIN response from the other party. B can now send a FIN to A and then await its acknowledgement (Last Ack wait).
Which classes are used for connectionless socket programming?
Socket and ServerSocket classes are used for connection-oriented socket programming and DatagramSocket and DatagramPacket classes are used for connection-less socket programming. The client in socket programming must know two information: IP Address of Server, and. Port number.
How does TCP connection is initiated and terminated?
To establish a connection, TCP uses a three-way handshake. Before a client attempts to connect with a server, the server must first bind to and listen at a port to open it up for connections: this is called a passive open. ACK: Finally, the client sends an ACK back to the server. …
When a connection is terminated the session need not be terminated?
Normal Connection Termination The connection as a whole is not considered terminated until both sides have finished the shut down procedure by sending a FIN and receiving an ACK. Thus, termination isn’t a three-way handshake like establishment: it is a pair of two-way handshakes.

In connection Termination : it takes four segments to terminate a connection since a FIN and an ACK are required in each direction. (3) means that sometime later the application that received the end-of-file will close its socket. This causes its TCP to send a FIN.
How does TCP guarantee the reliability?
Unlike UDP, TCP provides reliable message delivery. TCP ensures that data is not damaged, lost, duplicated, or delivered out of order to a receiving process. TCP achieves this reliability by assigning a sequence number to each octet it transmits and requiring a positive acknowledgment (ACK) from the receiving TCP.
