&lt;p&gt;The &lt;a href=&quot;QTcpSocket.html#QTcpSocket(com.trolltech.qt.core.QObject)&quot;&gt;&lt;tt&gt;QTcpSocket&lt;/tt&gt;&lt;/a&gt; class provides a TCP socket.&lt;/p&gt;
&lt;p&gt;TCP (Transmission Control Protocol) is a reliable, stream-oriented, connection-oriented transport protocol. It is especially well suited for continuous transmission of data.&lt;/p&gt;
&lt;p&gt;&lt;a href=&quot;QTcpSocket.html#QTcpSocket(com.trolltech.qt.core.QObject)&quot;&gt;&lt;tt&gt;QTcpSocket&lt;/tt&gt;&lt;/a&gt; is a convenience subclass of &lt;a href=&quot;QAbstractSocket.html#QAbstractSocket(com.trolltech.qt.network.QAbstractSocket.SocketType, com.trolltech.qt.core.QObject)&quot;&gt;&lt;tt&gt;QAbstractSocket&lt;/tt&gt;&lt;/a&gt; that allows you to establish a TCP connection and transfer streams of data. See the &lt;a href=&quot;QAbstractSocket.html#QAbstractSocket(com.trolltech.qt.network.QAbstractSocket.SocketType, com.trolltech.qt.core.QObject)&quot;&gt;&lt;tt&gt;QAbstractSocket&lt;/tt&gt;&lt;/a&gt; documentation for details.&lt;/p&gt;
&lt;p&gt;&lt;b&gt;Note:&lt;/b&gt; TCP sockets cannot be opened in QIODevice::Unbuffered mode.&lt;/p&gt;
