title: i'm a new to sockect programming for client。 A client creating a socket instance and connect(), is equivalent to creating a tcp connection?
body: <p>There is a http file server, now a client needs to download 10 files (within 50M) at the <em>same time</em>, how many tcp connections need to be created and how many sockets need to be created for the client?</p>
  <p>My idea is to create 10 socket instances for simultaneous download, is this correct?</p>
