Mobile Application

Applications in mobile computing fall into the following three broad categories:

1)Stand-alone Applications- run entirely on mobile terminals in disconnect (detached) mode.

2)Simple Client-Server (C/S) applications-The connection time for C/S interactions is short.

3)Advanced mobile applications - (groupware and distributed multimedia) - information exchanged is time critical (i.e., real time

The functionality of the mobile terminals has evolved tremendously over last 15 years.

Voice Transmission -Short Message Service (SMS) and Web Browsing Interaction with Vending Machine and Multimedia Message Service (MMS) Video Conferencing and Interaction with the surrounding physical environment -Object-to-Object Communication -Machine-to-Machine Communication Because of all above requirement symbian OS came in to picture to develop new and advance applications.
