socket(AF_INET, SOCK_DGRAM) creates this type of socket

when contacted, the server will create a new server-side socket to communicate with that client

provides reliable, in-order byte-stream transfer (a “pipe”), from client to server

a server can perform an accept() on this type of socket

the application must explicitly specify the IP destination address and port number for each group of bytes written into a socket

provides unreliable transfer of a groups of bytes (“a datagram”), from client to server

socket(AF_INET, SOCK_STREAM) creates this type of socket

data from different clients can be received on the same socket

socket(AF_INET, SOCK_DGRAM) creates this type of socket

The  application code at the server determines client IP address and port # from the initial segment sent by client, and must explicitly specify these values when sending into a socket back to that client.

As the result of performing the accept() statement, the server has created a new socket that is bound to that specific client, and so sending into this new socket (without explicitly specifying the client IP address and port number) is sufficient to ensure that the sent data will be addressed to the correct client.

The server will know the port number being used by the client since all services have a well-known port number.

The server will query the DNS to learn the IP address of the client.

This causes the client to reach out to a TCP server to establish a connection between that client and the server. If there is already one or more servers on this connection, this new server will also be added to this connection.

This causes the server to reach out to a TCP client to establish a connection between that client and the server.

This procedure creates a new socket at the client, and connects that socket to the specified server.
