Computer Science


This course aims to introduce students to the fundamentals of computer science in order for them to develop an understanding of the background of the functioning of modern digital computers. It also aims to introduce them to structured programming using the Pascal language. Alongside the teaching of the course familiarisation with common wordprocessing, spreadsheet and internet software is targeted in order that students can survive the everyday demands of IT in preparing projects and other university assignments.


There is no recommended book for this course. Reading material mainly consists of teacher notes that aim to cover the various aspects of the course but reference to user guides for the various software applications is also made. Much of the material used for this course can be downloaded from internet sites free of charge.
