If we are establishing a connection between client and server using TCP, it offers a number of features, including the fact that TCP is well-suited for applications that demand high dependability and transmission time is less important. It is utilized by protocols such as HTTP, HTTPs, FTP, SMTP, and Telnet. TCP rearranges data packets according to the requested order. There is an absolute guarantee that the transferred data will arrive undamaged and in the same order as it was sent. TCP utilizes Flow Control and requires three packets to establish a socket connection prior to sending any user data. TCP controls both dependability and congestion. It also does error detection and recovery. From the source to the destination, incorrect packets are retransmitted.
Explanation:
TCP Server –
using socket(), Create a TCP socket.
using bind(), Bind the socket to the server address.
using listen(), put the server socket in a passive mode, where it waits for the client to approach the server to make a connection
using accept(), At this point, the connection is established between the client and server, and they are ready to transfer data.
