| 10 | \brief The QTcpSocket class provides a TCP socket. |

| 16 | TCP (Transmission Control Protocol) is a reliable, |
|---|
| 17 | stream-oriented, connection-oriented transport protocol. It is |
|---|
| 18 | especially well suited for continuous transmission of data. |
|---|
| 19 | |
|---|
| 20 | QTcpSocket is a convenience subclass of QAbstractSocket that |
|---|
| 21 | allows you to establish a TCP connection and transfer streams of |
|---|
| 22 | data. See the QAbstractSocket documentation for details. |
|---|
| 23 | |
|---|
| 24 | \note TCP sockets cannot be opened in \l QIODeviceBase::Unbuffered mode. |
