Answer: Mainframe, Mini, Micro, and Super computers.
Description: Computers are classified based on their size, processing power, and usage. Mainframes are large and powerful, used in organizations for bulk data processing. Mini computers are smaller, used in mid-sized businesses. Micro computers are personal computers like desktops and laptops. Super computers are the most powerful, used for complex simulations and research.

Answer: Analog computers process continuous data (e.g., temperature), while digital computers process discrete data (e.g., 0s and 1s).
Description: Analog computers use physical quantities like voltage to represent data and are used in specialized applications like weather forecasting. Digital computers, like modern PCs, use binary code and are more versatile. Hybrid computers combine features of both.

Answer: Input, Processing, Output, Storage, and Communication.
Description: A computer system takes data as input (e.g., via keyboard), processes it using the CPU, produces output (e.g., on a monitor), stores data (e.g., on a hard drive), and communicates (e.g., via the internet). These functions work together to make a computer useful.

Answer: Peripherals like keyboards handle input, monitors provide output, hard drives enable storage, and network adapters support communication.
Description: Peripherals are external devices that extend a computer’s capabilities. For example, a mouse inputs data, a printer outputs results, and a modem facilitates communication over networks.

5.
Answer: Keyboard, Mouse, System Unit, and Monitor.
Description: These components are essential for a computer to function. The keyboard and mouse input data, the system unit processes it, and the monitor displays the output. Together, they form the core of a computer setup.
