Explain the different Scenarios involved in TCP 3 way handshake ?

Question

Is there any difference between operating system and network operating system ?

Answer 1

The TCP three way handshake is the process for establishing a TCP connection.We can explain 3 way handshake with a simple scenario where we assume a client computer is contacting a server to send it some information.

a) The client sends a packet with the SYN bit set and a sequence number of N.

b) The server sends a packet with an ACK number of N+1, the SYN bit set and a sequence number of X.

c) The client sends a packet with an ACK number of X+1 and the connection is established.

d) The client sends the data.

The first three steps in the above process is called the three way handshake.
