Using Sockets with Connections

The most common communication styles involve making a connection to a particular other socket, and then exchanging data with that socket over and over. Making a connection is asymmetric; one side (the client) acts to request a connection, while the other side (the server) makes a socket and waits for the connection request.

• section Making a Connection, describes what the client program must do to initiate a connection with a server.
• section Listening for Connections and section Accepting Connections describe what the server program must do to wait for and act upon connection requests from clients.
• section Transferring Data, describes how data are transferred through the connected socket.
