Brief Overview of Course The course is designed to introduce students to the concepts and scientific principles of computers. It does not rely on the knowledge of higher mathematics, but merely presupposes a certain amount of curiosity, creativity, and logical ability. It covers in details the digital computer organization, ICT, programming concepts as well as number systems.

Course Objectives/Goals A good understanding of the definition, fields and significance of computer science Appreciate the basic organization of the computer by describing the various parts and how they function. Describe the different types of computers in terms of their size, genealogy, speed and functionality. Understand the role and application of computer science in ICT. Define a language and differentiate between the various kinds of computer languages. Describe software and its related issues like ethics, piracy, patents etc. Understand the various software engineering issues. Understand and describe each of the four standard number systems. Convert from one number system to the other and then perform binary, octal and hexadecimal arithmetic.
