The Postgraduate Certificate in Applied Science (PGCertAppSc) allows students to begin postgraduate study with a 60 point qualification from which they can later proceed to a Postgraduate Diploma or Master's degree. This option allows students to maintain employment while gaining qualifications. Computer Science is the study of computers and the work they do. We need a science of computers because, unlike other machines, computers are general purpose; the same machine can perform many different tasks and the same tasks can be done equally well by different computers. Because of this, the study of what a computer can do is more than the study of a particular machine. It is the study of what can be done by a device which processes information. Naturally Computer Science papers deal with the practical matter of making the computer do what we want it to (programming). But we also deal with many other questions about computing and computers. How do they work? How are they used? How do they fit into our society? What are their limitations? Today computers are used not only as a tool in commerce and science, but also for research in many disciplines, such as Anthropology and Linguistics. Computer Science can be taken as a major for both the Bachelor of Arts and Bachelor of Science degrees and can also be included as a supporting subject in a Bachelor of Commerce degree. Some knowledge of computing is useful to all science students and many arts and business students even if you do not intend to major in Computer Science. Structure of the Programme The programme of study shall consist of approved 400- and 500-level papers, to the value of 60 points, selected from the papers specified in Science Schedule D for the Master of Applied Science subject concerned. shall normally include papers from more than one subject. may, with the approval of the Head of Department or Course Director concerned, include papers worth up to 20 points from 400-and 500-level papers other than those specified in Science Schedule D.
