CHAPTER ONE

1.0    INTRODUCTION

         Background of the study

Early computer systems were very large and very expensive. A typical mainframe computer cost millions of dollars and required hundreds square feet of specially air conditioned office space. In the first two decades (1950-1970) of computers, they were limited on their power and capabilities and reliability. Large companies could only afford them for batch processing, scientific, business or financial data on a large scale and the operation was by a specialist only. One of the major developments of computing technology in the 60’s was the concept of timesharing system. A time sharing system allows more than one user-often as many as several hundreds to use the same computer.  Simultaneously, users could run their own program, and each user interact with the computer through a terminal. By the mid 70’s due to cheap micro-technology, micro-computers were developed and personal computing distributed processing were in great demands especially business management. The need to share information and passing data between different computers arouse.

1.1      STATEMENT OF THE PROBLEM

There was a growing demand for wide spread, rapid and voluminous data transfer. Therefore, the motivation exists to find a way around these difficulties. The network of computer host-linked to a large number of terminals and shared peripheral equipment communication with the computer, takes place through the serial interface. The problem was that a wire-direct connection is only suitable for very short distance connection of about 20 meters.

Beyond this range, some sort of telecommunication facilities must be used such as a modern, Hub Routers, Radio, Communication system, satellite etc to make it work. If this project is implemented, the lost of transfer data, during communication is not greatly reduced. The speed of information transmission to every part of the world will be increased with the use of wireless network.

1.2            PURPOSE OF THE STUDY

The reason for this project work is to provide a wireless network, which can communicate and link so many terminals to a workstation through antennas, satellites etc. so that the cost of buying network cables will be reduced.

The use of these antennas and satellites helps to remove the difficulties involved in the layering of cable to a very far distance or to across oceans and rivers, to get connected to all the parts of the world. Wireless network also discourages the running of cables from one Land to another and to reduce cost of information management since there is no need to leave the computer system to another to get needed information or equipment.

The study of this project eliminates the wasteful utilization and duplication of resources. It also provide the need to be both informed and rightly placed to educate and advice clients on PC wireless network connectivity which is an added significance of this study.

1.3         AIMS AND OBJECTIVES

The project will achieve some objectives which include the following:-

The E-mail which is also know as a computer based management system (CMS) is a facility that allows users to compose and exchange messages while file management transfers a potion of a file from one system to another under the command as a FTP user.
