The three-way handshake in Transmission Control Protocol (also called the three message handshake) is the method used to establish and tear down network connections. This handshaking technique is referred to as the 3-way handshake or as "SYN-SYN-ACK" (or more accurately SYN, SYN-ACK, ACK). The TCP handshaking mechanism is designed so that two computers attempting to communicate can negotiate the parameters of the network connection before beginning communication. This process is also designed so that both ends can initiate and negotiate separate connections at the same time.
Host A sends a TCP SYNchronize packet to Host B
Host B receives A's SYN
Host B sends a SYNchronize-ACKnowledgement
Host A receives B's SYN-ACK
Host A sends ACKnowledge
Host B receives ACK.
TCP socket connection is ESTABLISHED
To understand the TCP split-handshake attack you need to understand how network devices build TCP connections. I'm going to assume you are familiar with the TCP three-way handshake. If not,this guide will walk you through it. Most network administrator understand this three-way handshake technique quite well, and many gateway security devices (like stateful firewalls) are designed to enforce it. However, less people know about another legitimate way to build TCP connections, called the simultaneous-open handshake. With a simultaneous open connection, both a client and server send a SYN packet to each other at about the same time. Then both sides also send ACK packets to each other in response. This slightly different variant of the TCP handshake doesn't happen much in the real world, however, it's a perfectly legitimate way to start a TCP connection (according to RFC 793).
The TCP three way handshake describes how two systems using the TCP protocol "talk to each other" to begin communication. The correct sequence is SYN, SYN-ACK, ACK

It synchronizes both ends of a connection by allowing both sides to agree upon initial sequence numbers.

The "Mason Handshake" refers to one of the modes of recognition in Freemasonry, and is considered a secret to Masons. Its purpose is so that one Mason may recognize another in complete darkness.
yes
No one except members know the Delta Chi handshake. This is because the handshake is only taught to members, who are then told not to share it with anyone else.
TCP/IP first
No one knows what the Alpha secret handshake is except the people who are in the group. This is because only members ever learn the handshake, and they are forbidden to tell outsiders.
TCP is a sub-protocol within the IP protocol. Think of TCP as one of the instruments in a band.
http needs a reliable mechanism to provide connectivity between the Host i.e. the web browser and the Server i.e the web server. Now TCP is the transport layer protocol that provides it reliable communication with three-way handshake mechanism it uses to connect between a client and a server. We also have UDP at transport layer but it is not reliable way of communicating. So http uses TCP at transport layer of OSI Model.
A firm handshake.
Transmission Control Protocol (TCP) is one of the core protocols of the Internet protocol suite.
A handshake and Guten Tag.
It's a handshake only a FIJI will ever know. ...But yea in reality the handshake is call-return type of handshake. When you approach a FIJI the handshake starts with the two parties clasping hands as a normal handshake would. BUT, person one presses with their thumb, followed by pressing with their pinky. In response, person two presses with their pinky, followed by pressing with their thumb. It's pretty simple, seems kinda dumb but who am I to judge, just some drunk FIJI told me on Spring Break.
