If message is UNPIN , server must unpin all notes relevant to .

If message is CLEAR, server must forget all notes which are not pinned.

If message is DISCONNECT, server will disconnect the connection with the

client.

Requirements :

Socket programming in python

Design and document an application-layer protocol.

Develop a client-server network application using stream socket API ( TCP ) of Python

Make sure to use TCP as the transport protocol

that implements the protocol you documented.
