Hello,Â
Hope you are doing good. I was reading a magazine of networking and a doubt comes in my mind that is tcp connection flow chart has 3-way handshaking. I have a confusion on the last part, At the end does client sends an acknowledgement to server or not. Thanks.
Greetings Marc A White,
Â
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
Â
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).
Â
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
