AIMS AND OBJECTIVES OF THE COURSE
The aims and objectives of this course include the following:
1. to understand fundamentally the general scope of the computer system
2. to interact effectively with the computer
3. to know the uses of the basic components of the computer
4. to manage the system to some extent before involving an expert
5. to know some basic things about the computer and the world
Computer as a revolution left no area of life untouched in the present world. It is of tremendous help in
all field of life. Hence, the knowledge of computer is a necessity for the existence of everybody in this global
village. The invention of the computer has transformed our simple manual works to sophisticated life of automated
works to meet the global demand for higher productivity and increased efficiency with high precision.
A computer is increasingly becoming compulsory in nearly all fields of studies, not because of anything
but its accuracy and versatility in processing data. Many tasks at home or office are being automated rapidly
with the computer. Thus it is becoming apparent that in whatever discipline or working sector, the computer is now
a very vital tool for efficiency improvement and precision of job or task execution.
This is designed to meet the prerequisite need of everybody that are interested and wish to know about
computers science and computing in general.
A computer is an electronic device, operating under the control of instructions stored in its own memory.
These instructions tell the machine what to do. The computer is capable of accepting data (input), processing
data arithmetically and logically, producing output from the processing and storing the results for future use.
Most computers that sit on a desktop are called Personal Computers (PCs).
The “computer” is an ensemble of different machines that you will be using to get your job done. A
computer is primarily made of the Central Processing Unit (usually referred to as the computer), the monitor,
the keyboard, and the mouse. Other pieces of hardware are commonly referred to as peripherals.
In everyday life activities, we process data or encounter cases of data processing. A typical example of
data processing is the generation of the statement of student result from the marks score in an examination and
continuous assessment. It is essential to know that information is as good as the data from which it is derived,
and the transformation process which they are subjected to. Meaningless data or inappropriate processing
produces the wrong information. Thus the computer gives you results corresponding to what data you supply and how you process it (i.e. gabbage- in, gabbage-out).
Summarily, the intelligent performance of a computer depends on the correctness of input data and the
intelligence performance of the human being that drives it.
