False. SMTP (Simple Mail Transfer Protocol) is responsible for sending or transferring emails from the sender's mail server to the recipient's mail server.
In computer networks, a socket refers to a combination of an IP address and a port number. It is a communication endpoint that allows two processes to communicate with each other over a network. A socket is identified by a unique combination of IP address and port number.
Sockets are essential in network programming as they enable processes running on different hosts to communicate with each other. When a process sends data to a socket, it is transmitted over the network to the socket at the other end, where the receiving process can read it. Similarly, when a process receives data from a socket, it has been transmitted over the network from the remote end.
Sockets can be classified into two types: stream sockets and datagram sockets. Stream sockets provide a reliable, connection-oriented communication channel, while datagram sockets provide a connectionless, unreliable communication channel.
I hope this helps!
