General - Aim of the Department

Computer Science, a relatively new science, started as a topic of limited scope, restricted to the automation of mathematical computations. Soon, however, it evolved into an exciting mixture of theory and technology, having as its central study theme the problem and its calculation, extending from the study of the theoretical (and philosophical) aspects of abstract problems to the effective solution of specific problems with practical significance. It is worth noting that the fundamental principles behind the theory of Computer Science emerge from the works of Ancient Greeks.

The dramatic advances in Computer Science as well as its contributions to the scientific community allow us to predict with certainty that its new fields of study will contribute to the scientific progress and they will constitute the basis for the further development of Computer Science and other future sciences. Those new fields of study include: parallel processing (the construction and programming of ultra fast computers using multiple - sometimes thousands of - processing units); the automation of formal reasoning and logic along with their usage in the systematic design and validation of software; robotics with its exciting applications in industry and space sciences; the construction and deployment of distributed information systems; the theory of algorithms which covers the whole computational spectrum, and many others.

The Department of Computer Science aims at contributing to the scientific advances in every aspect of Computer Science. To this end, the Department has set three key objectives: recruitment of prominent faculty members, expansion of its research activities and continuous improvement of its postgraduate and undergraduate programmes. It is our belief that the students of an academic department constitute the basis for its existence and its development while its graduated students constitute the driving force for society's development. As a consequence, one of the primary goals of the Department is to equip its students, through its study programmes and its numerous scientific activities, with an appropriate body of knowledge which will allow them, upon graduation, to occupy vital professional, research or academic positions.

Structure of the Department - Sections

At present, due to the limited number of its academic staff, the Department is not subdivided into separate Sections.

Laboratories and Research Units

A significant part of the Department's Study Programme and Research Activities is based on the use of computational systems.
For this purpose, the Department has the following Educational and Research Laboratories:

UNIX Laboratory: an educational laboratory with 25 SUN 4 workstations for the Department's undergraduate students.

Programming Laboratory: an educational laboratory with 21 SUN IPX workstations for learning programming languages and operating systems.

Microprocessor Laboratory: an educational laboratory with 24 personal computers.

Computing Research Laboratory: high-performance computers for research assignments. A SUN 3000 PC with two SILICON GRAPHICS R8000 processors, two SUN 5 and SUN 20 file servers with the correspondding peripherals.

Postgraduate Student Laboratory: Laboratory with 10 SUN 5 workstations for the Department's postgraduate students.
