Four years ago Palm created the first successful PDA. Today it holds an 80% share of the market for handheld computers. Its most serious competition is a family of devices from various vendors based on the Windows CE operating system. In some ways the competition between these two systems is reminiscent of the earlier Macintosh-Windows battle. Users become familiar with a device and develop strong preferences.

GLOBAL SYSTEM
FOR
MOBILE COMMUNICATION

Definition:
Global system for mobile communication (GSM) is a globally accepted
standard for digital cellular communication. GSM is the name of a
standardization group established in 1982 to create a common European
mobile telephone standard that would formulate specifications for a
pan-European mobile cellular radio system operating at 900 MHz. It is
estimated that many countries outside of Europe will join the GSM
partnership.

1. Introduction to Cryptography:
In the era of information technology, the possibility that the information stored in a person’s computer or the information that are being transferred through network of computers or internet being read by other people is very high. This causes a major concern for privacy, identity theft, electronic payments, corporate security, military communications and many others. We need an efficient and simple way of securing the electronic documents from being read or used by people other th ....etc
