5. Answer the following questions in short:
(a) What is a Microprocessor?
A microprocessor is the central processing unit (CPU) of a computer integrated onto a single chip. It performs arithmetic, logic, control, and input/output (I/O) operations based on instructions from a program.
(b) What is a Laptop Computer?
A laptop computer is a portable personal computer with a built-in display, keyboard, and battery. It is designed for mobility and can perform all the functions of a desktop computer.
(c) What is a Digital Computer?
A digital computer processes data in binary form (0s and 1s). It performs calculations and logical operations using digital circuits and is used for applications like word processing, gaming, and simulations.
(d) Name One Analog Device:
An example of an analog device is a thermometer.
(e) What is a Hybrid Computer?
A hybrid computer combines the features of both analog and digital computers. It can process both continuous (analog) and discrete (digital) data. An example is a computer used in medical applications like ECG machines.
6. Answer the following questions:
(a) What is a Microcomputer? Name any two microcomputers.
A microcomputer is a small, relatively inexpensive computer with a microprocessor as its central processing unit (CPU). It is designed for individual use and typically includes a monitor, keyboard, and storage.
Examples:
- IBM PC
- Apple Macintosh
(b) Classify Computers on the Basis of Size and Explain in Brief
- Microcomputer: Small, affordable computers for personal or small business use. Examples: Laptops, desktops.
- Minicomputer: Medium-sized computers used for tasks requiring greater computing power than microcomputers. Examples: Servers for small businesses.
- Mainframe Computer: Large systems used by organizations for bulk data processing and critical applications. Example: IBM zSeries.
- Supercomputer: Extremely powerful computers used for complex computations like weather forecasting or scientific simulations. Example: Cray supercomputers.
(c) Differentiate Between Microcomputer and Supercomputer
| Aspect | Microcomputer | Supercomputer |
|---|---|---|
| Size | Small, portable | Large, room-sized |
| Processing Power | Low | Extremely high |
| Use Case | Personal tasks (word processing, browsing) | Complex calculations (weather models) |
| Cost | Affordable | Very expensive |
(d) Classify Computers on the Basis of Working Principle and Explain in Brief
- Analog Computers: Work with continuous data. They measure physical quantities like temperature or speed. Example: Speedometers.
- Digital Computers: Work with discrete data using binary numbers (0 and 1). Example: PCs, laptops.
- Hybrid Computers: Combine features of both analog and digital systems. Example: Medical diagnostic systems like ECG machines.
(e) What is a Supercomputer? Write its Uses.
A supercomputer is a high-performance computer that can perform millions of calculations per second. It is designed for tasks that require massive processing power.
Uses:
- Weather forecasting
- Scientific simulations
- Drug discovery
- Cryptography
- Space exploration
(f) Differentiate Between Analog and Digital Computers
| Aspect | Analog Computer | Digital Computer |
|---|---|---|
| Data Type | Continuous data (physical quantities) | Discrete data (binary numbers) |
| Accuracy | Less accurate, approximate results | High accuracy |
| Speed | Fast for specific tasks | Slower than analog for continuous data |
| Examples | Thermometer, speedometer | Desktop PC, laptop |
