  Introduction
  It is my aim in this assignment to produce a java application that will act as a proxy server. The application a PDA server (PDAServer) will allow a PDA device installed on the GUI client to connect to a server on request and send it English text strings. The PDA server that we are developing will then pass on the English text strings to another server (TranslationServer) which will translate the English text string pass them back to the PDA server and in turn to the PDA device. Although all of the applications will run from a PC in effect we are creating a mock up of how such a system would work in effect in a post office or airport. The connection between the PDA and the PDA server would be a wireless one.
  
  Also in the assignment I will be writing an essay on ubiquitous and context aware computing describing the technology and future applications associated with the field. In particular I want to look at the implications which ubiquitous and context aware computing will have on security and privacy.
  Design
  We will first need to set the port numbers for which the PDAServer will listen on being
       3000 for the Translation server
       3001 for the PDA client (GUI)
  
  The next step will be to establish a connection to the PDA client and wait for text strings to be sent. A feature must be included by where if the PDA client sends a string "bye" the application will close down. This will be achieved by modifying the code provided in the coursework handout...
