The 8-bit unsigned integer 1000 in binary is equal to which decimal value? (a) 64 (b) 256 (c) 128 (d) 255
सही उत्तर: घ) 255
Converting binary 1000 to decimal: (1 * 2^3) + (0 * 2^2) + (0 * 2^1) + (0 * 2^0) = 8. Option (a) is the correct answer, because it represents 8 as a hexadecimal number.

In computer architecture, what does ALU stand for? (a) Advanced Logic Unit (b) Arithmetic and Logic Unit (c) Automated Language Understanding (d) Analytical Learning Utility
सही उत्तर: ख) Arithmetic and Logic Unit
ALU stands for Arithmetic and Logic Unit. It is the part of a CPU that performs arithmetic operations (addition, subtraction, etc.) and logical operations (AND, OR, NOT, etc.). Options (a), (c) and (d) are incorrect.

The hexadecimal number 7B4 is equal to which decimal number? (a) 2864 (b) 3194 (c) 3046 (d) 514
सही उत्तर: ग) 3046
Hexadecimal uses base-16. Converting 7B4 from hexadecimal to decimal: (7 * 16^2) + (11 * 16^1) + (4 * 16^0) = (7 * 256) + (11 * 16) + 4 = 1792 + 176 + 4 = 1972. Option (a) is incorrect. Option (b) is the correct answer.

What is the output of the following C code? `int i = 5; for (i = 0; i < 5; i++); printf("%d", i);` (a) 5 (b) 0 (c) 1 (d) Error
सही उत्तर: क) 5
The loop increments `i` by 1 in each iteration. However, the increment step is omitted, so the condition `i < 5` will always be true after the initial value of `i = 5`. Therefore, `i` retains its value of 5 and is printed. Options (b), (c) and (d) are incorrect.

The decimal number 11001010 is equivalent to which binary number? (a) 101010 (b) 1010010 (c) 110100 (d) 1001010
सही उत्तर: ख) 1010010
Binary numbers are based on powers of 2. Converting 11001010 to binary reveals that it is equivalent to 1010010. Option (a) incorrectly represents the binary value. Options (c) and (d) have incorrect digits.

In computer programming, what does the term 'loop' primarily refer to?
सही उत्तर: ख) B. A sequence of instructions that is repeatedly executed until a specific condition is met.
A loop allows you to repeat a block of code multiple times based on a certain condition or number of iterations, automating repetitive tasks in programming.

The term ‘bandwidth’ in computer networking refers to:
सही उत्तर: ख) B. The maximum rate at which data can be transmitted over a connection.
Bandwidth is the capacity of a transmission medium – typically measured in bits per second (bps) – which determines how much data can be transferred within a given timeframe. It’s not about cable size or security measures.

The electric field intensity at a distance 'r' from a point charge ‘Q’ is given by E = kQ/r². What is the value of k? (दूरी 'r' मा बिन्दु चार्ज 'Q' बाट विद्युत क्षेत्र शक्ति E = kQ/r² द्वारा दिइएको छ। k को मान के हो?)
सही उत्तर: क) 1
The value of 'k' is Coulomb's constant, which has a specific numerical value (approximately 8.98755 × 10^9 N⋅m²/C²). The provided options are illustrative values and do not represent the actual mathematical constant. Therefore, ‘None of these’ is the correct choice.

A stone is thrown vertically upwards with an initial velocity of 15 m/s. What is the maximum height reached by the stone before it starts to fall back down? (एक ढुङ्गालाई 15 मिटर / सेकन्डको सुरु वेगसँग ऊर्वरोधमाथि थ्रो गरिएको छ। ढुङ्गाले फर्किँदा पहिले उच्चतम गहिराइ कस्तो हुन्छ?)
सही उत्तर: ग) 30.6 m
Using the kinematic equation v² = u² + 2as (where v is final velocity, u is initial velocity, a is acceleration due to gravity (-9.81 m/s²), and s is displacement), we can find the maximum height reached at time t, where v=0. Calculating this gives approximately 25.9m.

The refractive index of glass with respect to air at a particular temperature is 1.5. What is the apparent depth of a swimming pool if its actual depth is 10 meters? (एक विशेष तापक्रममा गिलासको हावा सम्बर्द्धता 1.5 छ। यदि पूलको वास्तविक गहिराइ 10 मिटर छ भने, दृश्य गहिराइ कस्तो हुन्छ?)
सही उत्तर: ख) 8 meters
The apparent depth is calculated using the formula: Apparent Depth = Actual Depth * (1 - Refractive Index). Option 5, 5 meters, represents this correct calculation. The options of 8, 10 and 12 are incorrect because they don't consider the refraction effect.
