Is tcp connection flow chart is 3-way handshaking

Greetings Marc A White,

 

Let's assume you are sending me a mail over TCP. Here's how it works. In order for you to send me something you first need to check if I'm on the address. Therefore first you send a check-mail. So

 

Marc sends a check-mail (it's called SYN) to Cyril.

Cyril receives check-mail (SYN)

Cyril sends check-mail (SYN) and mail (ACK) that he is here.

Marc receives check-mail (SYN) and mail (ACK).

Marc now sends mail (ACK) to Cyril.

Cyril receives mail (ACK).

 

Maybe the check-mail, mail example isn't so good but I hope you understand how it works.

Hope this helps you,

Regards.

Dear Marc A White,

Thanks for asking a basic but very important question whoever wants to understand networking clearly. As my fellow expert already described you the step by step process very nicely I will not waste too much time of yours. But I just like to add a picture which I hope gives you more clarity on the issue.

I hope above picture will help you in removing any confusion. The picture shows that Client infact sends an acknowledgement to server for full fledge connection establishment.

Thanks & Regards,

DBD
