1.Analyze how the classifications of Mainframe, Mini, Micro, and Super computers determine their practical applications in industries.
2.Evaluate the advantages of using a hybrid computer instead of a purely digital one in a specific scenario, like automotive testing.
3.Assess how the five functions of a computer system work together in a smartphone to perform a task like video streaming.
4.Predict the impact on a computer system if the storage function fails, using a school project as an example.

- Answer: Mainframes manage large-scale data (e.g., banking), Minicomputers support mid-sized operations (e.g., retail), Microcomputers serve personal tasks (e.g., home use), and Supercomputers handle complex simulations (e.g., climate research).
- Description: Mainframes process millions of transactions daily, like in banks, due to their power. Minicomputers run store inventories efficiently. Microcomputers, like PCs, edit documents or browse the web, while supercomputers model weather patterns with massive calculations. This shows how size and power tailor computers to specific roles, critical for industry planning.
2.
- Answer: Hybrid computers excel in automotive testing by combining analogโs real-time signal processing (e.g., engine vibrations) with digitalโs precision (e.g., data analysis), offering faster, more accurate results than digital alone.
- Description: In car testing, analog components monitor live engine signals, while digital parts crunch numbers for efficiency stats. A purely digital system might lag in real-time response, missing subtle flaws. Hybrids blend both strengths, making them ideal for dynamic, precision-driven tasksโshowing students the value of type-based choices.
3.
- Answer: Input (touchscreen taps), Processing (decoding video), Output (screen display), Storage (buffering data), and Communication (Wi-Fi streaming) integrate seamlessly to deliver video.
- Description: Tapping a video app (input) sends data to the CPU, which processes it (decoding). The screen shows the video (output), the phone stores chunks temporarily (storage), and Wi-Fi fetches more (communication). This interplay shows how functions combine in modern devices, deepening hardware understanding.
4.
- Answer: Without storage, a school project canโt save work, halting progress after input and processing, as data vanishes when the system restarts.
- Description: Typing a report (input) and formatting it (processing) work fine, but without storage (e.g., a crashed hard drive), the file isnโt saved. Restarting loses everything, and output (printing) becomes impossible. This highlights storageโs critical role and teaches troubleshooting basics.
