1.
- Answer: The four classifications are Mainframe (large, powerful, for big organizations), Mini (smaller, for medium businesses), Micro (personal computers), and Super (extremely fast, for complex tasks).
- Description: Mainframes handle massive data, like banking transactions. Minicomputers support smaller networks, like in offices. Microcomputers, such as laptops, are for individual use. Supercomputers, used in weather forecasting, process huge calculations fast. Understanding these helps students identify the right computer for a task.
2.
- Answer: Digital computers use binary (e.g., PCs), analog use continuous signals (e.g., thermometers), and hybrid combine both (e.g., medical devices).
- Description: Digital computers process 1s and 0s, like a smartphone calculating apps. Analog computers measure physical changes, like a speedometer. Hybrid computers, such as ECG machines, analyze both continuous heart signals and digital data. This distinction shows how computers suit different needs.
