Basic Computer MCQs — Practice & Prepare
✅ Correct answer: JS Kilby
Jack S. Kilby (working at Texas Instruments) developed the integrated chip (IC) around 1958, a breakthrough that earned him a share of the 2000 Nobel Prize in Physics.
✅ Correct answer: microprocessors
Personal computers (PCs), considered fourth-generation machines, are built around microprocessors — single chips that integrate the entire central processing unit (CPU) onto one piece of silicon.
✅ Correct answer: fifth generation computer
Artificial Intelligence, along with natural language processing and expert systems, is a defining feature associated with fifth-generation computing, an area still evolving today.
✅ Correct answer: Both 'A' and 'B'
In the latest generation of computers, instructions can be executed both sequentially (one after another) and in parallel (multiple instructions at once), using multi-core processors and advanced parallel processing techniques.
✅ Correct answer: Personal computer
A personal computer is a small, microprocessor-based computer specifically designed to be used by one person at a time, making it the standard type of computer for individual, everyday use.
✅ Correct answer: Robotics
✅ Correct answer: system unit, input/output, secondary storage
A microcomputer's hardware is generally divided into three basic categories: the system unit (containing the CPU and memory), input/output devices, and secondary storage (like hard drives) for long-term data retention.
✅ Correct answer: microcomputer
A Tablet PC is classified as a type of microcomputer — a small, single-user computer built around a microprocessor, just like desktops and laptops.
✅ Correct answer: laptops
Laptops are portable computers designed for convenience and ease of use for people who travel, combining a full computer system into a compact, battery-powered, foldable device.
✅ Correct answer: microcomputers
Desktop and personal computers fall under the broader category of microcomputers — small, affordable, single-user computers built around a microprocessor chip.
✅ Correct answer: A PDA
A PDA (Personal Digital Assistant) is a small handheld device that uses a handheld operating system, designed for portable personal organization and basic computing tasks.
✅ Correct answer: handheld computer
A palmtop computer is also known as a handheld computer, referring to its compact size that allows it to be held and operated in one hand.
✅ Correct answer: server
A server is a central computer that stores and manages collections of data and programs, providing shared resources and services to many connected PCs, workstations, and other devices on a network.
✅ Correct answer: Mainframe
A mainframe computer is generally the most expensive type of computer among these options, built for large organizations needing to process massive volumes of data and support many simultaneous users.
✅ Correct answer: node
Users typically access a mainframe or supercomputer through a terminal — an input/output device (keyboard and screen) connected to the central, more powerful machine, rather than having independent processing power themselves.
✅ Correct answer: Supercomputers
Supercomputers are specially designed to perform extremely complex calculations at extraordinarily high speeds, making them ideal for tasks like weather forecasting, scientific simulations, and cryptography.

A ……… is a large and expensive computer capable of performing scientific and business applications.
✅ Correct answer: supercomputer
A supercomputer is a large, extremely expensive computer built to handle intensive scientific and business applications requiring massive computational power beyond what standard computers can offer.
✅ Correct answer: continuous electrical pulses
Analog computers work by processing continuous electrical signals (or other continuously varying physical quantities), unlike digital computers, which process discrete binary values.
✅ Correct answer: Analog computer
A seismograph, which measures continuously varying ground vibrations during earthquakes, is a classic example of an analog computer/device, since it processes continuous physical signals rather than discrete digital values.
✅ Correct answer: Digital computer
Microcomputer, minicomputer, supercomputer, and notebook computer are all classifications based on a computer's physical size and processing power, while 'digital computer' is instead a classification based on how data is processed — making it the odd one out.
