SECTION A: FUNDAMENTAL COMPUTING

1. Computer Hardware & Office Systems

A desktop computer is used in a school office for typing documents and storing student records.

• Hardware Components:

  • (a) Two components found inside the computer system (e.g., Motherboard, RAM, CPU).

  • (b) Function of the CPU: To process instructions and manage data flow between components.

  • (c) Primary vs. Secondary Memory: Primary memory (RAM) is volatile and faster, while secondary memory (HDD/SSD) is non-volatile and used for long-term storage.

• Software Types:

  • (a) Two types: System software and Application software.

  • (b) Example for records collection: Microsoft Excel or Access.

  • (c) Utility Software: Software designed to help analyze, configure, or maintain a computer (e.g., Antivirus, WinZip).

• Internet Connectivity:

  • (a) Two office uses: Email communication and cloud storage/research.

  • (b) Risks: Malware/Viruses and unauthorized data breaches (hacking).

  • (c) Internet Services: World Wide Web (WWW) and File Transfer Protocol (FTP).

2. Data Communication & Algorithms

In a workshop, information is sent between devices using cables or wireless links.

• Data Transmission:

  • (a) Two modes: Simplex, Half-duplex, or Full-duplex.

  • (b) System components: Sender, Receiver, Medium, Message, and Protocol.

  • (c) Medium: Fiber optic cable, Twisted pair, or Radio waves.

• Algorithms & Problem Solving:

  • (a) Algorithm: A finite set of step-by-step instructions to solve a specific problem.

  • (b) Flowchart Task: Create a flowchart to calculate the product of two numbers using successive addition.

  • (c) Qualities of a good algorithm: Finiteness, Unambiguousness, and Effectiveness.

• Networking:

  • (a) Network devices: Switch, Router, or Hub.

  • (b) Physical vs. Logical Topology: Physical refers to the actual layout of cables; logical refers to how data travels through the network.

  • (c) Switch vs. Hub: A switch sends data only to the specific destination port, reducing network traffic/collisions.

3. Control Systems & Databases

A water tank is fitted with a system that controls the flow of water automatically.

• Industrial Control:

  • (a) Example: Automated bottling plant or climate control systems.

  • (b) System Type: This is a closed-loop system because it uses sensors to monitor water levels and adjust flow.

  • (c) Importance of Feedback: It allows the system to adjust its output based on the actual conditions to reach the desired state.

• The ALU (Arithmetic Logic Unit):

  • (a) Operations: Arithmetic (Addition) and Logical (AND/OR comparisons).

  • (b) Task: Performing calculations and making logical decisions.

  • (c) Temporary Storage: Results are stored in Registers (specifically the Accumulator).

• Database Management:

  • (a) Advantages over paper: Faster data retrieval and better data security/integrity.

  • (b) School use: Tracking student attendance or managing grade reports.

  • (c) Software example: MySQL, Oracle, or Microsoft Access.

4. Automation in Industry

In a factory, machines operate automatically to perform repetitive tasks.

• Automated Systems:

  • (a) Task: Car assembly (welding/painting) or packaging goods.

  • (b) Reason for Automation: Increased consistency/precision and the ability to work 24/7 without fatigue.

  • (c) Role of Sensors: To detect physical changes (heat, pressure, proximity) and send data to the controller for decision-making.
