What is the difference between tcp and ip

TCP and IP are two different protocols in the Internet: 1. TCP is a transport layer protocol, while IP is a network layer protocol; 2. TCP provides segmentation, sorting, Functions such as confirmation and retransmission, while the IP protocol is responsible for providing source and destination addresses for data packets; 3. TCP is a connection-oriented protocol, while the IP protocol is connectionless; 4. TCP also provides flow control and congestion control.

TCP (Transmission Control Protocol) and IP (Internet Protocol) are two different protocols in the Internet, and they play different roles in network communication.

1. IP (Internet Protocol):

   • IP is a network layer protocol used to uniquely identify and locate devices (such as computers, servers) on a network and router).
   • The IP protocol is responsible for providing source and destination addresses for data packets to ensure that the data is correctly routed to the destination in the network.
   • The IP protocol is connectionless and does not care about the reliability and order of packet transmission.

2. TCP (Transmission Control Protocol):

   • TCP is a transport layer protocol built on top of the IP protocol to provide reliable , connection-oriented data transmission.
   • TCP provides functions such as segmentation, sorting, confirmation and retransmission of data packets to ensure the integrity and reliability of data transmission.
   • TCP also provides flow control and congestion control to adjust the rate of data transmission to adapt to changes in network conditions.
   • TCP is a connection-oriented protocol, which requires data transmission only after the two communicating parties establish a connection.

Therefore, IP is responsible for the addressing and routing of devices in the network, while TCP is responsible for reliable data transmission over the established connection. In the Internet, IP and TCP are often used together to form the TCP/IP protocol stack to achieve reliable data transmission and network communication.
