WebQTcpSocket encapsulates a TCP socket. It inherits from QIODevice, so you can use QTextStream and QDataStream to read or write data. It is useful for writing both clients and servers. QTcpServer allows you to listen on a certain port on a server. It emits a newConnection () signal every time a client tries to connect to the server. WebTCP (Transmission Control Protocol) is a reliable, stream-oriented, connection-oriented transport protocol. It is especially well suited for continuous transmission of data. QTcpSocket is a convenience subclass of QAbstractSocket that allows you to establish a TCP connection and transfer streams of data.
