The computer machine and computer technologies are both human oriented.

Though, the computer is brilliant and intelligent, it cannot compete with human. This is to say that the computer technology excellence of intelligence is desirable from the human elements that interact with the system and technology to make it work. It is whatever this human element commends the computer to do that is does.  Computer is absolutely harmless except it is imbued with the tendency to harm.

       Computer is basically defined as an electronic machine which accepts data form an input devices, perform arithmetic  and logic operations in accordance with defined data and finally transfer the processed data to an output device through the central processing unit (CPU) either for further processing or to be produced as a final result.

       Computer technology has come to be accepted as an indispensable in Motivation if fraud detection and prevention in the banking industry.

       Fraud has for a long time now remained the cancer-warm that is biting hard on the back bone of banking  industry.  The effect of this phenomenon has led to the liquidation of many banks in Nigeria.

       It has been the major cause of the ugly development in our Banking industry now refereed to as ‘DISTRESS’

       The development which records high occurrence of our banks has caused a big question mark on the credibility of Nigerian in both with and outside the country.  The need to combat the double –headed monster by all means gave rise to the issue of cultiviatism of the banking industry especially in the areas susceptible to fraud.


Since 1986 when structural adjustment programme was introduced, the banking business changed.  As the number of branches grow form sixty five in 1985 to one hundred and fifty five in 1994, the techniques of delivering bank services changes.

In November 1990, society general Bank launched their first Acitomated teller machine (ATM) with trade name SGBN’S Aim’s cash point 24.  The followed by first bank of Nigeria Plc in December 1991 with their ATM called “First cash” located in six branches in Lagos.

The House journal of first Bank of Nigeria (1991) affirmed that prior to AIM, other forms of electronic banking existed notable among which were computers. The computerization of Enugu (Main) branches in April, 1989 and also the recent introduction of local Area network (LAWS) or the 26th of October, 1999 and the Reengineering projects which will usher in the wide Area net work (WAN) before the next millenium.

But how far has the computer networking of these banks improved the long stay of customer on the counter; could manual application of interest on savings accounts, commission, on turnover and overdraft account handled automatically by the system? Can management always extract up to data information or account position of the operation at a particular point in time.

The state of the banks services t customers are such that customers are made to stay helplessly on the counter for hours, only to be attended to by neatly dressed impolite bank cashier.   The security checks are simply cumbersome and bank staff wishing to stay on their employment vigorously follow these procedures.

       Then bank manager and he staff  seem not to bother as they profiled form chars queues generate.  It created in them an area of self importance and a customer who is time conscious will have to see him/her in his/her company officer for behind the counter deal.

       However, there is no doubt that the fear of fraud slaved down bank services and has militated against performing any feast in the art of quick and excellent quality service.

       The experience of the banks is that any money that goes out by mistake does not come back and there are many people who are prepared to rob the bank through fraud.  But computer has helped a lot in the detection and it prevention in banking industry.

       Computer is defined as a machine which accepts data from an input devices which perform arithmetic and logical operations in accordance with define data and finally transfer the processed data to and output device in through the Central Processing Unit (C P U), either for further processing or to be produced as a final result.

It can be also defined as an electronic machine that accepted data, processes the data as   instructed and produces an output.  The data to be processed is fed into the computer by means of an input device.  We note two important fact about the operations of the computer.

1.    The computer does nothing on its own initiative.  It is always guided by an internally stored set of instructions know as a program.   As a matter of fact, the computer has no initiative.

2.    The nature of the output is based on the validity of the instructions given to the computer during a particular problem solving process.  A functional computer has two component, namely the hard ware and software.

COMPUTER HARDWARE:   Computer hardware is a collective term that refers to any physical component of the  computer system, which can be seen, touched, handled, or felt. These various hardware items that make up the computer perform various functions when the computer is in use.     The broad processes the computer hardware carries are.

1.   Accept data and program instructions.

2.    Process the data using the instructions

3.    give an out put or result of the processed device.

4.    Store the data.

The computer hardware has four component

1.      Input unit

2.      Output unit

3.      Central Processing Unit

4.      Storage unit.
