Basic Computer: Types & Classification MCQ — 15 Practice Questions with Answers

Explanation

The match depends on the main use of each class. A supercomputer is used where very high processing speed is needed, such as scientific simulation and weather modelling. A mainframe is used by large organisations for reliable, high-volume transaction processing. A workstation is a powerful single-user machine meant for engineering, design, or technical work. An embedded computer is built inside another device, such as a washing machine controller or vehicle control unit, for a fixed task. Therefore the correct sequence is I-1, II-2, III-3, IV-4.

Explanation

An embedded computer is a computer built into a larger product to control, monitor or support a particular function. Examples include the controller in a washing machine, a microwave oven, a digital camera or a car engine-control system. The assertion is true because such computers are usually not seen as separate desktop-like machines. The reason is also true because their design is tied to a specific task or a small set of tasks. This task-specific design explains why they are built into larger devices, so both A and R are true and R explains A.

Explanation

A microcomputer is the small, general-purpose computer class built around a microprocessor and normally used by one person at a time. In exam terminology, personal computers are included in this class. Desktop computers, laptops, notebooks, and tablets are common examples. So Statement 1 gives the defining usage pattern, while Statement 2 gives correct examples. The question is not asking whether these are the fastest or largest computers; it is asking their size and user-based class. Hence both statements are correct.

Explanation

Computers classified by data handling are analogue, digital, and hybrid. Analogue computers work with continuous physical quantities such as temperature, pressure, or speed. Digital computers work with discrete values. A hybrid computer combines both: it can take continuous physical measurements and then process or display the result in digital form. The stem gives both clues: the inputs are varying body signals, and the output is a digital reading for the doctor. Therefore, the best classification is hybrid computer.

Explanation

A general-purpose computer can perform many different tasks depending on the software used, so the personal computer used for typing, browsing and accounting matches I-1. A special-purpose computer is designed for a particular job; an ATM computer handling cash transactions is a standard example, so II-3 is correct. An embedded computer is built into another machine or appliance and controls it from inside. A washing-machine controller fits this idea, so III-2 is correct. The correct matching is I-1, II-3, III-2.
