Basic Computer: Fundamentals & Characteristics MCQ — 15 Practice Questions with Answers

Explanation

GUI stands for Graphical User Interface. It presents commands and choices through visual elements such as icons, windows, menus, buttons and a pointer. Because users can click and select instead of remembering many typed commands, a GUI is generally easier for beginners than a command-line-only interface. The assertion says that GUI improves ease of use for beginners, and the reason gives the exact mechanism behind that ease. Therefore both statements are true, and the reason correctly explains the assertion.

Explanation

Standard computer characteristics include speed, accuracy, diligence, storage capacity, versatility and automation after instructions are given. However, a computer does not possess independent common sense or judgement like a human being. It follows the programme and the data supplied to it. If the logic or input is wrong, the result may also be wrong. Since the question asks for what is not a usual characteristic, "independent common sense" is the odd choice.

Explanation

The basic working cycle of a computer is input, processing and output. First, raw data and instructions are entered through input devices. The CPU then processes that data according to the instructions. Finally, the result is produced as output, which is useful information for the user. The stem asks how raw data becomes information, so the order must start with input and end with output. Hence, Input → Processing → Output is correct.

Explanation

A keyboard is used to enter letters, numbers and commands, so it is a text input device. A monitor displays results on the screen; this is soft-copy output because it is visible electronically and not printed on paper. A printer produces a physical paper copy, so it is hard-copy output. A mouse controls the pointer and selects items on screen, so it is a pointing input device. Hence the correct matching is I-2, II-3, III-4 and IV-1.

Explanation

RAM and ROM are basic memory terms. RAM is Random Access Memory and is volatile: its contents are normally lost when power is switched off. It works as the computer's active workspace for running programmes and current data. ROM is non-volatile and commonly stores firmware or start-up instructions that the computer needs during booting. The stem states exactly these two standard facts. Therefore both Statement I and Statement II are correct.
