Basic Computer MCQs — Practice & Prepare
✅ Correct answer: Fourth Generation
Fourth-generation computers (from the early 1970s onward) replaced discrete ICs with microprocessors, single chips that combined the entire CPU as a switching device.
✅ Correct answer: Fourth
Large Scale Integration (LSI), Very Large Scale Integration (VLSI), and Ultra Large Scale Integration (ULSI) chips are all hallmarks of fourth-generation computers.
✅ Correct answer: Nanoseconds
Third-generation, IC-based computers operated at speeds measured in nanoseconds, a major leap over the microsecond speeds of second-generation transistor machines.
✅ Correct answer: Fifth Generation
Fifth-generation computing, focused on artificial intelligence, natural language processing, and parallel processing, is still an evolving, ongoing area of development.
✅ Correct answer: Fifth Generation
Artificial intelligence, including expert systems and natural language processing, is a defining focus of fifth-generation computing.
✅ Correct answer: All of above
Natural language processing, artificial intelligence, and bio-chip research were all envisioned features that define fifth-generation computing.
✅ Correct answer: Knowledge information processing system
Fifth-generation computers are also called Knowledge Information Processing Systems, reflecting their emphasis on AI, expert systems, and natural language use.
✅ Correct answer: Fourth generation
The original Apple Macintosh, released in 1984, was built using fourth-generation microprocessor technology.
✅ Correct answer: Super Computers
Supercomputers are engineered purely for maximum raw processing power, making them the most powerful class of computers, well beyond mainframes, minis, or micros.
✅ Correct answer: None of above
Laptop, tablet, and desktop PCs are all types of microcomputers, so there is no correct exclusion among these options.
✅ Correct answer: Mini Computers
Minicomputers, mid-sized and moderately powerful, are commonly used as servers to support the networking and data needs of medium-sized organizations.
✅ Correct answer: Super Computers
Supercomputers, built with cutting-edge components for extreme processing power, are by far the most expensive class of computer.
✅ Correct answer: Micro Computers
Small, single-user computers built around a microprocessor are called microcomputers — the category that includes what we now call personal computers (PCs).
✅ Correct answer: Micro Computers
Microcomputers are typically single-user machines and, unlike mainframes or minicomputers, generally cannot support multiple users working simultaneously.
✅ Correct answer: USA
The first working digital computers, such as the ABC, ENIAC, and EDVAC, were all developed in the United States during the 1930s-40s.
✅ Correct answer: Supercomputers are focused to execute few programs as fast as possible while mainframe uses its power to execute as many programs concurrently
A supercomputer devotes its massive processing power to running very few, highly complex programs (like weather simulation) as fast as possible, while a mainframe is built to run many programs for many users at the same time.
✅ Correct answer: Mainframe Computer
Mainframe computers are physically large, powerful systems designed to serve many users and handle massive workloads, making them the largest common computer classification alongside supercomputers.
✅ Correct answer: They produced heat and often burned out
Vacuum tubes generated a great deal of heat and burned out frequently, making first-generation computers unreliable and expensive to maintain.
✅ Correct answer: Third generation
Third-generation computers (1965-1971), built with ICs, introduced more user-friendly features such as keyboards, monitors, and early graphical interfaces.
✅ Correct answer: ICs
Integrated Circuits (ICs) are fabricated on semiconductor material, usually silicon, allowing many transistors to be etched onto one small chip.
