Q1Read the Assertion and Reason: Assertion (A): A GUI makes a computer easier for beginners to use. Reason (R): A GUI lets users work with icons, windows, menus and a pointer instead of relying only on typed commands. Choose the correct answer.
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.
Q2Which of the following is NOT a usual characteristic of a computer?
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.
Q3In the basic input-process-output cycle of a computer, which sequence correctly shows how raw data becomes useful information?
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.
Q4Match the items in List I with their correct category in List II: List I: I. Keyboard II. Monitor III. Printer IV. Mouse List II: 1. Pointing input device 2. Text input device 3. Soft-copy output device 4. Hard-copy output device Select the correct code.
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.
Q5Consider the following statements about RAM and ROM: Statement I: RAM is a volatile memory used for data and programmes currently being worked on. Statement II: ROM usually stores permanent instructions needed to start the computer. Which option is correct?
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.
