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.

How do you have a three way call?
to have a three way call you have to call a party. Then, you press flash, and call another party. After it rings, press flash again and you will be in a three way call.
When was three way calling invented?
The forerunner of three way calling was conference calling. Conference calling was introduced to the public in 1964, and three way calling was established as a pay service with phone companies shortly thereafter.
What is the purpose of using feedback to improve communication skills?
The purpose of receiving feedback is so you can determine the best way for you to communicate with others and what you're most suited to.
Main differences between WPA and WPA2?
Wi-Fi Protected Access 2 (WPA2) builds upon WPA, which makes them very similar. Both support identical Extensible Authentication Protocol (EAP) types in an enterprise environment, as well as allowing pre-shared keys (PSKs). Group key transmission is performed by the two-way handshake, while the four-way handshake is used for unicast generation. The main differences are as follows: - WPA requires Temporal Key Integrity Protocol (TKIP), and it supports Advanced Encryption System (AES), which provides a stronger encryption - WPA2 requires AES, and it does not support TKIP
How to do three way calling on a house phone?
you call the first person you wanted to call and then press flash and then called the second person and then press another flash and there you go , a three way call.
Operates at the transport layer of the osi model and provides reliable data delivery services?
TCP The three way handshake verifies that data arrived
What is one purpose of the TCP three-way-handshake?
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.
Which type of attack exploits the TCP three-way handshake to open multiple half-opened TCP connections to prevent valid users from accessing the server?
A: SYN flood attack

What is the function of the tcp three-way-handshake?
It synchronizes both ends of a connection by allowing both sides to agree upon initial sequence numbers.
What process is used to establish a TCP connection?
The term typically used is the '3-way handshake'.
Which event occurs during the transport layer three-way handshake?
TCP initializea the sequence numbers for the sessions.
A tcp connection is in 'established' state.................?
It is established after the 3-way handshake is complete and the channel is open between a sender and a receiver.
What is syn syn ack ack?
Syn Syn Ack Ack means three way handshake in Transmission Control Protocol. It is referred to as Syn Syn Ack Ack because there are three messages transmitted by TCP to negotiate and start a session between two computers.
What is handshake in packet transmission?
The TCP 3 way handshake is when the server states what ports it has open, the client requests access to the port, and the server grants access. Layman's terms: Server - I have beer at my place. Client - Can I come over? Server - Sure!
What is a TCP Handshake?
A TCP Handshake happens whenever a TCP connection is used. A TCP Handshake provides a small bit of security and is used to increase the reliability of IP communication. If the server is unavailable, too busy, or the connection between the client and the server is not reliable, the handshake will fail. The handshake will also fail if the requested port is blocked by a firewall or other filtering device.For example, when your computer visits wiki.answers.com, it does a TCP Handshake on the standard HTTP port, port 80, data is transfered, then the connection is closed.The client connects on port 80 with a SYN (Synchronize) and (if all goes well) the server replies with an ACK (Acknowledge) and another SYN (Synchronize). The client will reply with a final ACK (Acknowledge), completing the handshake.A client and server going through a TCP Handshake looks like this:Client: SYNServer: ACK/SYNClient: ACKOr to put it simply, if you asked your computer to visit wiki.answers.com (port 80), the handshake would look like this:Your Computer: Hi, wiki.answers.com! Can we talk on port 80? (SYN)Answers.com: Hi! Sure! (ACK) Are you ready? (SYN)Your Computer: Yep! (ACK)The above connection is known as a 3-Way Handshake.Once the TCP Handshake is complete, the client and server exchange data (with an ACK after every packet sent, to confirm that the packet safely reached it's destination with the correct checksum). Once the client and server are done, the handshake is finished and is closed.Once the connection is made, the server can still actively deny the connection. The server can choose to not reply to the first SYN from the client (which will make the server appear offline) or it can complete the TCP Handshake, then deny the connection (commonly known as an "active refusal").If you'd like to explore more about network packets, try downloading Wireshark, an open source packet capture utility.

What is connecton oriented protocal?
Where the network connection establishes a connection using the tcp/ip 3 way handshake before commencing transmission of data. Packets are guaranteed delivery to the destination node.
