Early man employed drawings to communicate even before he learnt to communicate, write or count. Incidentally, these earliest hieroglyphics or picture-writings communicate also today, as they should have done thousands of years ago, it saying that "A picture is worth a thousand words" and in the era of computers we can put in on to it or we may also revise the saying to "A computer is worth a million pictures!"; consequently, you can calculate approximately the power of a computer like a communication system.

Actually, the power and simple availability of computer graphics have raised the utilization of pictures to replace and augment words to explain, educate or notify a broad variety of audiences on a broad variety of subjects.

In this section, we shall concentrate on the graphic abilities and potential of the digital computer as well as we will talk about the meaning of the term graphics and its kinds, in addition to that, we will also talk about the hardware utilized for practical application of graphics in various streams of life. The software section conversely, will be discussed in this course.
