Detailed explanation-1: -Transmission Control Protocol (TCP) provides a secure and reliable connection between two devices using the 3-way handshake process.
Detailed explanation-2: -A TLS handshake takes place whenever a user navigates to a website over HTTPS and the browser first begins to query the website’s origin server. A TLS handshake also happens whenever any other communications use HTTPS, including API calls and DNS over HTTPS queries.
Detailed explanation-3: -Both HTTP GET and HTTP POSTS use TCP. If you are asking whether a POST also requires a 3-way TCP handshake (syn-synack-ack), it does just like any other TCP connection. The TCP handshake is required before any application protocol (such as HTTP) starts work.
Detailed explanation-4: -TCP uses a three-way handshake to establish a reliable connection. The connection is full duplex, and both sides synchronize (SYN) and acknowledge (ACK) each other.
Detailed explanation-5: -It is a three-step method designed to allow both communicating ends to initiate and negotiate the parameters of the network TCP socket connection at the same time before data such as HTTP and SSH is transmitted.
