Objectives: This course will enable the student to understand the basic organization of computer systems and system maintenance.
Note:
(i) The syllabus of this paper has been divided into four sections.
(ii) The examiner will set a total of nine questions, comprising two questions from each section and one compulsory question of the short answer type covering the whole syllabus.
(iii) The students are required to attempt one question from each section and the entire compulsory question.
(iv) All questions carry equal marks, unless specified.
(v) The student can use only a non-programmable & non-storage type calculator.
