TCPyhteyksistä
TCPyhteyksistä, or TCP connections in English, are a fundamental aspect of internet communication, enabling reliable data transfer between devices. TCP, which stands for Transmission Control Protocol, operates at the transport layer of the OSI model and is part of the TCP/IP protocol suite. It ensures that data is delivered accurately and in the correct order, making it suitable for applications that require high reliability, such as web browsing, email, and file transfers.
TCP connections are established through a three-way handshake process. This involves an initial SYN (synchronize) packet
Once established, TCP connections maintain a continuous flow of data, using sequence numbers to keep track
TCP connections can be terminated through a four-way handshake, involving FIN (finish) and ACK packets exchanged
In summary, TCP connections are essential for reliable data transmission over the internet, providing mechanisms for
