1.
- Answer: Input (enters data, e.g., keyboard), Processing (computes data, e.g., CPU), Output (displays results, e.g., monitor), Storage (saves data, e.g., hard drive), and Communication (connects devices, e.g., Wi-Fi).
- Description: Input brings data in, like typing a document. Processing turns it into something useful, like formatting text. Output shows it, like printing. Storage keeps it for later, and communication shares it, like emailing. These functions work together in every computer task.
2.
- Answer: Peripherals like keyboards (input), monitors (output), and external drives (storage) extend a computer’s capabilities.
- Description: A keyboard inputs text, a monitor outputs visuals, and a USB drive stores files beyond the internal hard disk. Peripherals make computers versatile—without them, you’d be limited to the system unit. This shows their practical role in daily use.
