1.0 Introduction

1.1 Background Of The Study

Computer since its evolution has made considerable impact to various areas in one society and the world in general. Its scientific study discovery and development both in the fields of science and technology owned to the strange swiftness, exact and accuracy with its activities of computer in many aspect of human endeavour lead to the speed and accurate execution of length and cumbersome fast.

Nevertheless, computer has been applied in most fields these days due to its benefits. It has been applied in the following areas.


Computers are used as an aid to students hearing, it acts as a patient teacher which allows learning at your own pace, through the use of multimedia.


Medical records of patients can be stored for later retrieval through the sue of computer thereby assisting in the tracing of medical history of patients for appropriate treatment, also due to the emergence of internet, later medicine is now possible (a situation whereby a patient can be treated via the internet.


Most business and large firms uses a computer package called word processing to write letters, memos and report. A word processing program makes correction, editing of documents quickly and easy resulting in a neat and readable output. Also the emergence of internet has made a business possible for buying and selling of products through the internet (i.e. E- commerce)


Some companies employ master job with the aid of computer based training program which most of them use in simulation technology and other package like CAM (computer Aided and manufacturing) and CAD (Computer Aided design) are used in design and manufacturing of other products.

Other areas of which computer application has been applied are in computerization of some government owned parastatals billing system (NITEL and PHCN) and computerization of airline reservation. Due to this and other mentioned benefits and reasons, computer is without guiding ground (popularity) while scientist, artists, engineering, doctors, business and education sectors etc, found computer helpful. Some computer packages used in achieving these goals are AutoCAD, DBASE, PowerPoint, etc.

In addition, it can helpful in the computerization of federal Polytechnic Nekede grade Point Average Computation system. The adopted manual method by the examination records and statistics and computer science department formally used in the execution and processing of both Grade point Average Computation System in accurate, slow and reasonable as it goes without human labour would create chance for eliminating mistakes and oversight, accuracy as a result of manual preparation of Grade Point Computation

Historical Background

According to Richard and Jeffrey (1988) computation is the process of performing mathematical operations on data. It is the only data processing techniques that produce new data (information/output), it is the ability to perform calculations quickly limitless millions of multiplication problem for record that gives computer their reputation of miraculous tools.

John (1997) a computer scientist and a writer to the success of a computer magazine once stated a major computer merit that cannot be cost in the computer speed shown in the processing of data within few seconds which when rated and compared with human labour would normally take days, weeks, months and even years, office academic institution etc are therefore advised and encouraged to embark on computerization.

1.2. Statement Of The Problem

The problem is to investigate the way the computer science department in federal Polytechnic Nekede prepare the grade point processing and analyze the system, design and implement a new computerized system that would timel6y and effectively process and transmit data.

1.3. Purpose Of The Study

The Grade point Average Computerization system is the focus of this project work. This study is carried out to examine the existing system in an attempt to identify its problems and the system required as to surface with relevant facts that will be of help in the design of a computer based.

Grade point Average computation will help management in the computation and preparation of a computer based package for student’s grade point.

This program (Grade Point average Computerization system Version 1.0) is very simple, structured to a reasonable extent quite educating and overall well documented.

The study has much usefulness such as:

  1. Fasting up the rate of computing students Grade and scores thereby the manually records and statistics department labour function eliminated.
  2. Provision of relief to tedious repetitive clerical work in preparation of grade Point average computation

1.4. Significance Of The Study

This study will go a long way into helping the management of computer since to cope with the problem encountered as a result of using manual system in the preparation of exam score and students records. It is hoped that this study will help in the efficient and effective operation of computer-based grade Point Average Computation system.

1.5. Scope Of The Study

5.0. Summary, Conclusion And Recommendation

5.1. Summary

Before the introduction of computer system in the early century, manual processing o f Grade Point calculation of grades in high institutions and other areas are in progress.

From research made it has caused an accelerated progression of incompetence especially on the absence of the grade point calculator in high institutions of learning. It created a wide range of vacuums in the educational sector which are:

  1. Inability to produce accurate result
  2. Inability to produce result on timely base
  3. Imposing stress on human brain
  4. Frequent misplacement of important papers or materials thereby creating a high level of cost expenditure
  5. Problem of poor security system

But the introduction of computerization procedure will be able to wipe all manner of incompetence that manual procedure has created in the past.

Hence, the implementation of Grade Point Average computation system (GPA) deals with the usage of computer system. I think that there will be no problem of inability to produce accurate result. Inability to produce result on time basis, stress on human, poor security and loss of important papers or material that manual processing is characterized with all these said things, grade point average computation system remains the a best method of processing GP calculation. Also Grade Point Average computation system will go a long way to the betterment of the calculation of grades in the higher institution and to her fields of higher learning.

5.2. Conclusion

The need to improve and reverse the existing system of grade Point Average computation processing in the department of computer science, Federal Polytechnic Nekede, Owerri, plays a very vital role of growing importance in all our lives endeavour. They are used in homes for games in hospitals for diagnosis and countless other areas

Computer is an electronic machine that process input at a very high speed and produce a reliable output through a unique set of instructions incorporated in them.

Therefore, to the best of my knowledge, the Grade Point average Computation System in the Department of computer science, Federal Polytechnic Nekede Owerri will yield accuracy in the processing of files reliable information, timelines and also reduction of human stress.

5.3. Recommendation

Based on the conclusion drawn above, I will recommend that the computer room should be well equipped with some auxiliary equipments, the new computer based system need to have uninterrupted power supply (UPS) system ad stabilizers installed along side with the computer system, this helps to hold current in case of power failure to avoid loss of important jobs in the system.

Moreso, as computer evolution progresses and becoming more sophisticated, there is need to purchase computer manuals, incorporate new software and train personnel., this will go a long way to provide satisfactory jobs.
