Preamble

The course gives students an overview of computer science: A foundation from which they can appreciate the relevance and interrelationships of further courses in the field. Computer Networks deals with components and principles of networks and its protocols. Operating System acts as a platform of information exchange between a computer’s hardware and the applications running on it. Database Management Systems have become a part of all computer based systems automating real word applications to handle data storage. This course provides an insight on the general structures of operating systems, database management systems and computer networks.
