Models and Computer Systems

Answers and Descriptions:

1. Answer: Input, process, and output.
   Description: The abstract model represents how data is transformed into information: input (raw data), process (analysis or computation), and output (meaningful information). This model aligns with computer operations, helping students understand the foundational structure of ICT systems.

2. Answer: A system is a set of interconnected components working together to achieve a common goal.
   Description: In ICT, a system (e.g., a computer or network) processes inputs to produce outputs. Defining systems helps students analyze how ICT components interact, reinforcing the abstract model’s relevance to real-world applications.

3. Answer: Input (weather sensor data), process (data analysis using algorithms), and output (forecast reports) align with the model, enabling accurate predictions.
   Description: Sensors collect temperature or humidity data (input), algorithms analyze patterns (process), and forecasts are displayed (output). Applying the model to real systems helps students bridge theoretical concepts with practical ICT applications.

4. Answer: Input devices, output devices, processing units, and storage devices.
   Description: Hardware includes components like keyboards (input), monitors (output), CPUs (processing), and hard drives (storage). Classifying hardware helps students understand the physical components of a computer system and their roles in ICT.

5. Answer: Proprietary software is owned and restricted by a company, while open-source software is freely accessible and modifiable.
   Description: For example, Microsoft Windows is proprietary, while Linux is open-source. Understanding this distinction helps students evaluate software choices based on cost, flexibility, and community support in IC
