This popular full colour course book has been revised to meet the requirements of the new CSEC syllabus in Information Technology. The course provides today's IT students with comprehensive coverage, including the School-Based Assessment (SBA). It is written with a fresh and highlyillustrative approach, and takes into account the challenges faced in today's classroom. A new section has been added to assist teachers and students who are new to programming. The book is also appropriate for practical management courses at UWI.
