The Computer: A Need for Device Drivers

A computer or a computing machine is a device which receives information, acts upon it, and furnishes the results in a form readable by either a person or by a machine. In most cases, the computer performs some mathematical operation upon the data which it receives. Sometimes, however, it is used simply to rearrange or translate information. The chief advantage of a computer is the speed with which it operates.

Among the various names by which computers are, or have been, known are mathematical machines, automatic data processors and colloquially, electronic brains and thinking machines. Actually, the latter two are misnomers, for a computer cannot think- it can only carry out those operations that a person has programmed, or instructed, it to perform. In this way, a computer functions as an extension of man’s intellect, just as a steam shovel, for example, functions as an extension of his muscles.

In little more than a decade, the computer has become an integral part of science, government, and business. Each year new ways to use these machines are being discovered. Technological developments have been so rapid and of such magnitude, that in some cases they have overlapped.

Despite its advanced stage, therefore, the computer must be considered to be in a continual state of development. Man has only just begun to understand how much this versatile tool can do for him. New components are continually being developed and existing ones refined. As programming techniques are advanced to utilize these improvements, expansion into new and presently uninvestigated areas will be increased.

Computer in itself is a complex machine. With the word machine alone, it is relatively made out of many parts. These parts help hand in hand to create the necessary output as it accepts input and utilizes this to process the output needed. The computer can also store data. It is the discretion of the owner as to saving his work or not. Indeed computer nowadays are very useful and that it is of big help to companies and even in little ones who are still learning. There are programs that help them learn and further understand their lessons in school.

Your body has different parts. Some parts help you move. Some parts help you observe things. Some even help you read and understand data and apply it in different aspects in life. Indeed, the whole is the sum of its parts. With missing parts, one cannot do an appropriate tasks built for the part that is missing. Computers too are made up of different parts. These parts work together in unison as they do their specific tasks.

Input devices. These are devices that serve as the computer’s eyes and ears, otherwise known as your senses. You get information through your eyes and ears. Similarly, computers take in information such as words and numbers. Among the input devices are the keyboard, mouse and the joystick. The keyboard looks like a typewriter. It has many buttons. The buttons on it are called keys. The keyboard is used to type in letters, numbers and symbols. The mouse on the other hand allows you to control the movement of the cursor. You can use the mouse to tell the computer what to do to perform commands and functions. The joystick is often used in games. It controls the movement and direction of objects displayed on the screen.

Processing device. It is like your brain. When you think, you use your brain. It is used to process data given to the computer. The central processing unit acts as the brain of the computer. It tells the other parts of the computer what to do.

Output devices. When the computer sends out information through one of its parts, usually printed or on the screen, it is called an output. They are used to show what the computer has done. Among the output devices are the monitor, printer and speakers.

Storage devices. You can save your work through this device. Among these storage devices are hard disk, diskette and a compact disk.

All of these, in order for it to work in unison is through the use of a computer device driver. This device driver acts as a messenger and as a bridge from one specific device to another. Such as your audio device, it needs an audio device driver for the CPU to understand the data and to relay it to the audio devices such as your speakers.

In all of this, there is only one lesson learned. “United we stand, divided we fall.” Each part has importance to the whole.
