TcpListener vs Socket

Hello i would like to ask what is difference between using this :

public TcpListener Listener;
public TcpClient Client;

Listener = new TcpListener(DeafultPort);
Client = default(TcpClient);
Listener.Start();

and this :

serverSocket = new Socket(AddressFamily.InterNetwork, 
                                      SocketType.Stream, 
                                      ProtocolType.Tcp);

IPEndPoint ipEndPoint = new IPEndPoint(IPAddress.Any, 1000);

and also i would like to know if i use first option what is difference between

Listener.BeginAcceptSocket()

and

Listener.Server.BeginAccept()

and if i use second option what exactly does these two lines ?

serverSocket.Bind(ipEndPoint);
serverSocket.Listen(4);

Thanks for answers
