Computer is a machine which today has been seen from different points of view. The data processing personnel sees the computer as a data processing machine that receives data as input, stores, processes and gives out information at a very fantastic speed. In electronics, it is seen as a mechanical device that takes in data as input, stores, processes, retrieves and gives out a desired output at a very fast speed. The information technologist sees the computer as a data processor which manipulates data to provide useful information, while the computer scientist sees it as the combination of hardwares and softwares which work together to give desired output.
Apart from the above, computer has been known generally as a machine that performs tasks, such as calculations or electronic communication, under the control of a set of instructions called a program. Programs usually reside within the computer and are retrieved and processed by the computer's electronics. The program results are stored or routed to output devices, such as video display monitors or printers. Computers perform a wide variety of activities reliably, accurately, and quickly.
An ideal computer system is a collection of appropriate devices needed for meaningful manipulation of data. It is the combination of the different parts or various units of a computer to give a computer system. The parts include the inputs, processing output and storage unit. The absence of any of these units makes a computer system incomplete.
I acquired my first computer in 1998, even though it has been in use for some time. Till today so many people do not know what computers are and what they do. The PC Magazine once said that an illiterate is not only one who does not know how to read and write, but one who does not know how to operate a computer. It is still possible, of course, to get along nicely in the computer age knowing little more than how to spell the word. The aura of magic that still surrounds computers is largely a fabrication. They employ no gimmicks or witchcraft. They obey the same laws of physics and mechanics.
Computers help us to do our work better and faster, and they have better memories than human beings. It should be noted that computers are not only more accurate but are more reliable. The computer's chief virtue is not to think, as many people mistakenly believe, but to help man do his daily work better. As a product of human intelligence, the computer is manufactured as an aid or spur, to human intelligence.
In weather forecast and general education, the computer has become a useful instrument since it can be infinitely patient, consistent, explaining the same concept over and over, trying different words or examples, without making a slip. In judgment, a computer is objective in analyzing errors, and it has been proved uninfluenced in deciding which ideas need to be clarified.
It is erroneous however, to say that computers do not err. One computer expert once said that computers do not actually err; only the programmers do. The point is that nothing is perfect in itself. If a perfect God could create imperfect human beings, people who are prone to mistakes, computers which are works, designs and products of imperfect creatures can never be perfect! The computer's insatiable appetite for the kinds of tedium that make people climb walls, and the fact that it never turns up its nose at any kind of assignment no matter how weird, does not still make it perfect.
When computers first came, they did not come in the state which they are today. Computer was invented by a Whiteman but a Blackman of Igbo extraction added speed to it. Its invention opened the way to hundreds and thousands of applications yet undreamed of. The computer is not the machine to end all machines. Contrary to the image it inevitably projects, it is not a perfect machine. Computers are still blind to emotions, a situation which reminds us that the computer is only a tool and an invention of an imperfect man.
