What Is Three-Way Handshake?
The three-way handshake means saying "Hi!" when you want to talk to someone. It goes like this. Client: Hello! Server: Hello! I'm glad you're here. Client: So am I! A three-way handshake is a TCP/IP network method to create a connection between a local host/client and a server. It occurs when a client sends an SYN packet to the server, replies with an ACK packet, and the client finally acknowledges an ACK packet of its own. The three-way handshake is important because it establishes the connection between two hosts to exchange data. The process consists of three steps: The client sends an SYN (synchronize) packet to the server.ACK: The server sends back an ACK (acknowledgment) packet that confirms receipt of the SYN packet from the client. ACK: Finally, the client sends back another ACK packet to confirm receipt of the ACK packet from the server. The three-tier client/server model is designed to allow both communicating ends to initiate and negotiate the network TCP socket connection parameters simultaneously before data such as HTTP and SSH is transmitted. This process enables both ends to choose the best route available in terms of speed, reliability, and cost while also allowing them to ensure that they use compatible encryption methods and protocols. The three-tier client/server model is based on the idea that one end must handle all communications while the other can only be used for processing tasks when needed. A three-way handshake is a protocol to establish a TCP connection between two devices. It's the first step in setting up reliable data transmission between clients and servers, making the Internet work. When browsing the web, your browser sends a request to a server asking it to send back some information. The server gets this request, verifies it, and returns an acknowledgment that everything is approved for transmission. Then your browser sends another bid for the data it needs, and voila! You can start reading your email or watching funny cat videos on YouTube.
