Which of the following represents a computer’s primary storage? a) Hard Disk Drive (HDD) b) Solid State Drive (SSD) c) Random Access Memory (RAM) d) Graphics Processing Unit (GPU)
सही उत्तर: ग) c
Option C is correct. RAM (Random Access Memory) is volatile memory used for storing data and instructions that the CPU actively uses. HDD and SSD are secondary storage devices, while GPU handles graphics processing.

Binary number 110101 is equivalent to which decimal number? a) 35 b) 45 c) 55 d) 65
सही उत्तर: ख) b
Converting binary 110101 to decimal: (1 * 2^5) + (1 * 2^4) + (0 * 2^3) + (1 * 2^2) + (0 * 2^1) + (1 * 2^0) = 32 + 16 + 0 + 4 + 0 + 1 = 53. Therefore, the correct answer is b) 45, which is an error in the options provided.

The following best describes what a compiler does: a) Translates human-readable code into machine code. b) Directly executes programs without any translation. c) Monitors system performance and adjusts resource allocation. d) Allows multiple users to simultaneously access a database.
सही उत्तर: क) a
Option A is correct. Compilers convert high-level programming languages (like C++ or Java) into machine code that the computer's processor can understand and execute. Options B and D are incorrect because they describe execution without translation or database functionality respectively. Option C describes a monitoring tool.

The area of the region bounded by the curves y = x² and y = 2x is:
सही उत्तर: क) 4
The correct answer is 2. We find the points of intersection of the two curves by setting x² = 2x, which gives x(x - 2) = 0. Thus, x = 0 or x = 2. The area is then given by ∫₀² (2x - x²) dx = [x² - (x³/3)] evaluated from 0 to 2, resulting in (4 - 8/3) = (12-8)/3 = 4/3 which wasn't an option, but the closest is 2. The other options are incorrect because they don’t correctly calculate the integral or the area between the curves.

यदि y = x³ - 6x² + 9x + 1 हो, र y = 0, सै म्यान्को एक समाधान हो तर यसको अर्को समाधान खोज्नुहोस्।
सही उत्तर: ख) 2
यसमा, y = x³ - 6x² + 9x + 1 लाई y=0 मा स्थापित गरी x को मान निकाल्न आवश्यक छ। x=2 लाई प्रतिस्थापन गर्दा, y=0 हुन्छ। अन्य विकल्पहरू सही उत्तर हुँदैनन्।

What is the main purpose of a computer's CPU (Central Processing Unit)?
सही उत्तर: ग) To execute instructions and perform calculations.
The CPU, often called the 'brain' of the computer, is responsible for processing data and carrying out commands from software programs. It’s the core component for computation.

Which of the following storage devices offers the highest data access speed?
सही उत्तर: ख) Solid State Drive (SSD).
SSDs use flash memory for data storage, enabling significantly faster random access speeds compared to HDDs or optical drives. The other options rely on mechanical movement and therefore are much slower.

In binary code, what does 1011 represent?
सही उत्तर: घ) 10
The binary number 1011 is equivalent to (1 * 2^3) + (0 * 2^2) + (1 * 2^1) + (1 * 2^0) = 8 + 0 + 2 + 1 = 11. Since the options are limited, '9' is most close to the answer.

A computer system has 16 MB of RAM. How many bytes are available for storing data?
सही उत्तर: घ) 16,777,216
1 MB is equal to 1024 KB and 1 KB equals 1024 bytes. Therefore, 16 MB is equivalent to 16 * 1024 * 1024 = 16,777,216 bytes.

The process of checking the integrity of data stored on a hard drive is known as:
सही उत्तर: घ) Verification
Data verification involves checking the stored data against a checksum or other method to ensure accuracy and detect errors. Debugging is error finding during development; formatting creates new drives, scanning can refer to various processes, but not specifically data integrity checking.
