TCP, Transmission Control Protocol, is a network communication protocol designed to send data packets over the Internet.
What is TCP?
TCP is a connection-oriented protocol and a standard that allows systems to communicate over the Internet. It defines how to establish and maintain network conversations through which applications can exchange data; ensuring that data delivery, and ensure that the order in which data packets are sent is the same as the order in which data packets are sent.
TCP is a transport layer protocol in the OSI layer that is used to create connections between remote computers by transporting and ensuring the delivery of messages through supporting networks and the Internet.
TCP is one of the most commonly used protocols in digital network communications and is part of the Internet protocol suite. Together with IP, it is the basic rule that defines the Internet and is often called the TCP/IP suite.
How does TCP work?
We can think of TCP as establishing a connection between two endpoints. It mainly ensures end-to-end data connection and transmission between different nodes. TCP works in conjunction with the Internet Protocol, which defines the logical location of remote nodes, while TCP transports and ensures data is delivered to the correct destination.
Before transmitting data, TCP creates a connection between the source node and the destination node and keeps it valid until communication is active. TCP is responsible for breaking data into packets, buffering data, retransmitting lost or out-of-order packets, acknowledging receipt, and controlling the data flow rate by telling the sender to speed up or slow down so that the application never receives more data stream Can be handled.
