CHAPTER ONE

1.0           INTRODUCTION

          How is computer and other related devices able to send information across data communication lines? The answer to this is the installation and maintenance of computer network is the glue that holds data in the exact form. The data is to be transferred from one place to another. While the procedures for installations are embodied in this project.

1.1           STATEMENT OF PROBLEM

          Computer hardware may fail, telephone lines may fail and more likely the computer software may have bugs that could cause the network to stop working.

          How does the airline clerk sell or work when the computer is down? How can the pilot send a message across when the network fails? How do you get your electronic mail? Pay bills; get news, if you are dependant on computer network that sometimes fails.

          If you put a shared data base, you want to be sure that it will not disappear or be tampered with if you can use your home computer to read your account or toil with your money.

          A computer that puts all its important data in line runs the risk of going out of business if that information is lost or incorrect.

          Furthermore, suppose the owners of a saved data want certain people to use it, one way to limit use is to give a password across to those people alone that will have access to it and before opening the data base, the computer will ask the user to enter a password pass word protection is not parted though if someone finds out your password and uses it to access your computer the computer will not know that the password has been used illegally by such person. Inability of the computer scientist to observe appropriate procedure in connection during installation poses threat to them which however may lead to damage of the computer and cards

1.2           AIMS AND OBJECTIVES

The aims and objectives of the study are as follows

To minimize cost; with maintenance, there is reduction of cost i.e. instead of spending more money in purchase of new equipment, the money can be used in the maintenance of the faulty equipment.

To reduce staff; with the introduction of computers, there is the possibility that the number of will reduce.to share file and resources at a given time; with computer networks, files and other peripherals can be shared at any given time as printer, scanner, and files to increase output; with computer networks, jobs that are scheduled for ten days can be done in three days and this will increase output the overall objectives of the local area net work is to connect the computer systems and devices in the same geographical area.
