Sockets MCQ question and answer in javascript with solution

HTTP is a stateless protocol. A stateless protocol does not require the server to retain information or status about each user for the duration of multiple requests.

The readonly attribute readyState represents the state of the connection. It can have the following values:
1. A value of 0 indicates that the connection has not yet been established.
2. A value of 1 indicates that the connection is established and communication is possible.
3. A value of 2 indicates that the connection is going through the closing handshake.
4. A value of 3 indicates that the connection has been closed or could not be opened.

There are fourWebSocket events namely :
1. open
2. close
3. message
4. error

The Socket.close() is used to close the WebSocket.

The client and server communicate over a long-lived TCP socket following rules defined by the WebSocket protocol.

There is no Socket property called ready.

Once the connection is established, the client can determine which subprotocol is in use by checking the protocol property of the socket.

The Socket.send(data) method transmits data using the connection.

There is no WebSocket event named deny. The four WebSocket events are
1. open
2. close
3. essage
4. error
