SYLLABUS

Curricular Study Notes (Weeks 1 to 4)

🖥️ Week 1: Computer Hardware Components

Definition: Computer hardware refers to the physical, tangible parts or electronic components of a computer system that can be seen and touched.

Hardware is divided into five core categories:

  • 1. Input Devices: Used to feed raw data and instructions into the computer. Examples include the keyboard (typing text/commands), mouse (pointing and clicking), scanner (digitising printed papers), and microphone (voice capture).
  • 2. Output Devices: Used to present or display processed information to users. Examples include the monitor (visual display), printer (paper hardcopies), and speakers (sound).
  • 3. Processing Devices: The central machinery that interprets instructions and performs calculations. The Central Processing Unit (CPU) is the primary processing device and is known as the "brain" of the computer.
  • 4. Storage Devices: Used to permanently save files, operating systems, and programs for future use even after powering off. Examples include Solid State Drives (SSD), Hard Disk Drives (HDD), and USB Flash Drives.
  • 5. Communication & Network Devices: Allow computers to connect and share data/resources across a network. Examples include routers, modems, and wireless access points.
⚠️ Key Checkpoint: RAM vs. Storage

RAM (Random Access Memory) is temporary, volatile working memory used only while programs are running; it is cleared when the computer is turned off. Storage (SSD/HDD) is permanent, non-volatile memory used to preserve files indefinitely.

💾 Week 2: System Software and Application Software

Definition of Software: A set of programs, instructions, and data that tells computer hardware what to do. Unlike hardware, software is intangible and cannot be physically touched.

Interdependence: Hardware and software must work together. Without software, hardware is completely useless; without hardware, software has no machine on which to run.

Feature System Software Application Software
Purpose Manages, controls, and coordinates computer hardware operations. Enables end-users to accomplish specific user tasks.
Examples Operating Systems: Microsoft Windows 11, Apple macOS, Linux, Android. Microsoft Word (assignments), PowerPoint (slides), Chrome (browsing), Excel.
Independence Runs independently as soon as the computer is turned on. Cannot run without an underlying operating system.
User Interaction Works mainly in the background managing files and devices. Users interact directly with its features to do schoolwork.
🧰 Week 3: Computer Maintenance & Laboratory Care

Definition: Computer maintenance refers to the routine care, cleaning, and diagnostics carried out to keep computer systems operating reliably and efficiently, and to prevent breakdowns.

Four Reasons Why Maintenance is Essential:

  1. Improves System Performance: Prevents system slowdowns and lag by removing dust that causes CPU thermal overheating.
  2. Prevents Hardware Damage: Regular cleaning and proper ventilation protect internal electronic components from permanent burnout.
  3. Protects Valuable Data: Installing software updates and maintaining antivirus software guards against ransomware, viruses, and data loss.
  4. Increases Equipment Lifespan: Well-maintained lab computers remain operational for many years, saving significant replacement costs.
🧼 Hardware Care vs. Software Care

Hardware Care: Wiping dust off screens/keyboards with a lint-free microfiber cloth or compressed air; keeping liquids and snacks away; gentle cable management.
Software Care: Running antivirus definitions updates; installing operating system patches; removing temporary files; performing proper shutdown via the Start Menu (never pulling out the plug!).

🔄 Week 4: The Data Processing Cycle (IPOS)

Data: Raw, unorganized facts, numbers, or symbols without context (e.g. 45, 60, 75, 80). By themselves, they are not meaningful.

Information: Processed, organized data that has been given context and meaning (e.g. "Student Term Average = 65% with Grade B").

Data Processing: The sequence of steps taken to convert raw data into meaningful and useful information.

INPUT (Keyboard/Mouse) ➔ PROCESSING (CPU Calculations) ➔ OUTPUT (Monitor/Printer) ➔ STORAGE (SSD/HDD)
🏫 Classroom Case Study: School Examination Result System

1. Input Stage: Subject teachers type student marks into the school system using a keyboard.
2. Processing Stage: The computer calculates totals, computes class averages, and determines student grade positions.
3. Output Stage: The system displays the final scores on screen and prints student report cards.
4. Storage Stage: Student report sheets and transcripts are permanently archived to the school SSD server for future academic records.

🎯 "How to Pass Your Exams" — Student Masterclass
  • Rule 1: Decode Command Words: "Define" [1m] requires the exact technical meaning. "State" [1m] requires naming the device/action directly. "Explain" [1-2m] requires stating what happens AND giving the reason ("because... which results in...").
  • Rule 2: 1:1 Mark Matching: If a question awards [2 marks], provide 2 distinct, clearly separated points. One sentence alone will only get 1 mark!
  • Rule 3: Avoid Brand Names: In generic questions, write the category: write "Operating System" or "System Software" instead of just "Windows", and "Word Processor" instead of "Word".
  • Rule 4: Time Budget: Total test is 40 minutes for 20 marks: spend 15 minutes on CBT (MCQs), 22 minutes on Theory, and 3 minutes reviewing your answers.
