TCP connection initiates with the server by Browser

Once the IP address of the computer (where your website information is there) is found, it initiates connection with it. To communicate over the network, internet protocol is followed. TCP/IP is most common protocol. A connection is built between two using a process called ‘TCP 3-way handshake’. Let’s understand the process in brief:

1. A client computer sends a SYN message means, whether second computer is open for new connection or not.

2. Then another computer, if open for new connection, it sends acknowledge message with SYN message as well.

3. After this, first computer receives its message and acknowledge by sending an ACK message.
