The overall goal of Computer Science was to create the computer as a universal information processing device. This course is specially designed for those who want to quickly grasp the essence of Computer Science without going into abstract mathematical theories.

The course is composed of concise lectures, which reveal basic terms and steps which lead to understanding of how a computer is built and how it can be programmed with a programming language. The course is made as short as possible by avoiding proofs and long arguments, and mostly using only ready-made conclusions gained from research.

The course contains:

• Information and Data - what is the main subject of Computer Science.

• Researchers who have contributed most to the development of Computer Science - a brief historical overview of how Computer Science was created and what non-trivial problems had to be solved at different points in time. This information is important in terms of ordering and prioritizing Computer Science topics.

• Description of Data and the description of Algorithms are the two most important topics that, like axes of a coordinate system, hold the entire Computer Science system together.

• The design and basic operation of a digital computer - how the device was able to combine data processing based on typical algorithms.

• Finally, an example of a simple Pascal program that summarizes the knowledge from the previous lectures.
