It guides learners to explain core terms such as data, program, information, and data processing, and to describe computer unit roles during processing. The paper also addresses computer system unit components, computer generations and classification methods, types of computers and their differences, emerging microcomputer trends, and how computers are used across sectors. It further includes questions on computer laboratories, safety precautions, environmental and energy issues in installations, and ideal operating environments with ventilation requirements.","\u0013 TOC \\o \"1-3\" \\h \\z \\u \u0014\u0013 HYPERLINK \\l \"_Toc255201571\" \u0014INTRODUCTION TO COMPUTERS\t\u0013 PAGEREF _Toc255201571 \\h \u0014- 2 -\u0015\u0015\n\u0013 HYPERLINK \\l \"_Toc255201572\" \u0014COMPUTER SYSTEMS\t\u0013 PAGEREF _Toc255201572 \\h \u0014- 6 -\u0015\u0015\n\u0013 HYPERLINK \\l \"_Toc255201573\" \u0014OPERATING SYSTEMS\t\u0013 PAGEREF _Toc255201573 \\h \u0014- 13 -\u0015\u0015\n\u0013 HYPERLINK \\l \"_Toc255201574\" \u0014WORD PROCESSING\t\u0013 PAGEREF _Toc255201574 \\h \u0014- 16 -\u0015\u0015\n\u0013 HYPERLINK \\l \"_Toc255201575\" \u0014SPREADSHEETS\t\u0013 PAGEREF _Toc255201575 \\h \u0014- 18 -\u0015\u0015\n\u0013 HYPERLINK \\l \"_Toc255201576\" \u0014DATABASES\t\u0013 PAGEREF _Toc255201576 \\h \u0014- 23 -\u0015\u0015\n\u0013 HYPERLINK \\l \"_Toc255201577\" \u0014DESKTOP PUBLISHING (DTP)\t\u0013 PAGEREF _Toc255201577 \\h \u0014- 25 -\u0015\u0015\nINTERNET AND E-MAIL……………………………………………………….……-26-\n\u0013 HYPERLINK \\l \"_Toc255201578\" \u0014DATA SECURITY & CONTROL\t\u0013 PAGEREF _Toc255201578 \\h \u0014- 28 -\u0015\u0015\n\u0013 HYPERLINK \\l \"_Toc255201579\" \u0014DATA REPRESENTATION IN COMPUTERS\t\u0013 PAGEREF _Toc255201579 \\h \u0014- 30 -\u0015\u0015\n\u0013 HYPERLINK \\l \"_Toc255201580\" \u0014DATA PROCESSING\t\u0013 PAGEREF _Toc255201580 \\h \u0014- 32 -\u0015\u0015\n\u0013 HYPERLINK \\l \"_Toc255201581\" \u0014PROGRAMMING\t\u0013 PAGEREF _Toc255201581 \\h \u0014- 34 -\u0015\u0015\n\u0013 HYPERLINK \\l \"_Toc255201582\" \u0014SYSTEMS DEVELOPMENT\t\u0013 PAGEREF _Toc255201582 \\h \u0014- 42 -\u0015\u0015\n\u0013 HYPERLINK \\l \"_Toc255201583\" \u0014NETWORKING & DATA COMMUNICATION\t\u0013 PAGEREF _Toc255201583 \\h \u0014- 44 -\u0015\u0015\n\u0013 HYPERLINK \\l \"_Toc255201584\" \u0014APPLICATION AREAS OF ICT\t\u0013 PAGEREF _Toc255201584 \\h \u0014- 48 -\u0015\u0015\n\u0013 HYPERLINK \\l \"_Toc255201585\" \u0014IMPACT OF ICT ON SOCIETY\t\u0013 PAGEREF _Toc255201585 \\h \u0014- 50 -\u0015\u0015\n\u0013 HYPERLINK \\l \"_Toc255201586\" \u0014CAREER OPPORTUNITIES IN ICT\t\u0013 PAGEREF _Toc255201586 \\h \u0014- 51 -\u0015\u0015\nROADMAP TO KCSE …………………………………………..…………………….-52-\n\u0015\u000fKENYA CERTIFICATE OF SECONDARY EDUCATION\n451/1 COMPUTER STUDIES\nPAPER 1 (THEORY QUESTIONS)\nFORM ONE - INTRODUCTION TO COMPUTERS\nExplain the following terms as used in computer science:\nData.\t\t\t\t\t\t\t\t\t\t(1 mark)\nProgram.\t\t\t\t\t\t\t\t\t(2 marks)\nData processing.\t\t\t\t\t\t\t\t(2 marks)\nInformation.\t\t\t\t\t\t\t\t\t(2 marks)\nWhat role(s) does each of the following units of a computer play during data processing?\nInput unit.\t\t\t\t\t\t\t\t\t(1 mark)\nOutput unit.\t\t\t\t\t\t\t\t\t(1 mark)\nCentral processing unit.\t\t\t\t\t\t\t(2 marks)\nList down four characteristics of a computer.\t\t\t\t\t(4 marks)\nState four different parts that make up a computer.\t\t\t\t(2 marks)\n(a) Explain the term System Unit.\t\t\t\t\t\t\t(1 mark)\n(b) Name four components found in the System unit.\t\t\t\t(4 marks)\n(c) Outline three features of a computer’s System Unit.\t\t\t\t(3 marks)\n(a) What are peripheral devices?\t\t\t\t\t\t\t(1 mark)\n(b) Give two examples of peripheral devices.\t\t\t\t\t(1 mark)\n(a) Match the following generations of computers with the technology used to develop them.\t\t\t\t\t\t\t\t\t\t\t(2 marks)\n(b) Computers have evolved through a number of generations.
