OPERATING ILLUSTRATION PICTURES

1. Client to Server (port command): two-way connection.

• Client send the command to the server.
• Server reply by sending a menu of services based on the command for client to choose next command/action.

2. Server to Client (port file): one-way connection.

• Server bases on the command/action to transfer only the data or downloading files to the client.
