Network Introduction
A computer network allows sharing of resources and information among interconnected devices. In the 1960s, the Advanced Research Projects Agency (ARPA) started funding the design of the Advanced Research Projects Agency Network (ARPANET) for the United States Department of Defense. It was the first computer network in the world Development of the network began in 1969, based on designs developed during the 1960s.
Purpose
Computer networks can be used for several purposes:

ABSTRACT

So far transmission errors have been described as evil entity in communication literature. Introducing error intentionally can save power and reduce interference. This has been proved by scientists Jik Dong Kim (South Korea), Sang Wu Kim (USA) and Young Gil Kim (South Korea). It is about combined power and error control in multicarrier DS-CDMA systems ....etc

1. INTRODUCTION

In recent years, there has been a rapid increase in wireless network deployment and mobile device market penetration. With vigorous research that promises higher data rates, future wireless networks will likely become an integral part of the global communication infrastructure. Ultimately, wireless users will demand the same reliable service as today's wire-line telecommuni cations and data networks. However, there are some unique problems in cellular networks that challenge their service reliability. In addition to problems ....etc

The recent spat of daylight robberies at the jewelers has prompted us to undertake this project. This is a Research & Development project having commercial value. A typical situation in case of a daylight armed robbery is that miscreants enter the shop posing as customers, suddenly they brandish their guns and ask the shopkeepers to hand over cash and valuables. The phone lines are instantly cut and no one is allowed to leave the shop. There is absolutely no way to raise an alarm or contact the police. It is not even possible to take out a cell ....etc

TWO WAY STUDENT INFORMATION SYSTEM USING CELLULAR TECHNOLOGY
INTRODUCTION
The project basically works by sending students information's (IA marks, attendance and college updates) to their guardians using GSM modem.
A GSM modem works only using AT commands.
In case, If any parents want to know regarding their pupils then they can query the institute through messaging service number .
This queries are checked by authorized personals and further they will reply to their messages.
