![]() ![]() ![]() The communication over the network in TCP/IP model takes place in form of a client-server architecture. If an acknowledgment is not received, after a certain amount of time transmitted data will be lost and TCP automatically retransmits the data. TCP also offers the facility of retransmission, when a TCP client sends data to the server, it requires an acknowledgment in return. Major Internet applications such as the World Wide Web, email, remote administration, and file transfer rely on TCP. In TCP before sending the data it breaks the large data into smaller packets and cares the integrity of the data at the time of reassembling at the destination node. TCP creates a connection between the source and destination node before transmitting the data and keeps the connection alive until the communication is active. It ensures that data is delivered to the correct destination. TCP is designed to send the data packets over the network. It is an intermediate layer of the application layer and internet protocol layer in the OSI model. TCP (Transmission control protocol)Ī TCP (transmission control protocol) is a connection-oriented communication. In this article, I shall describe TCP/IP and write a socket program using the TCP/IP API. Before you start learning socket programming in C, you should basic knowledge of IP addresses, TCP, and UDP. ![]()
