A computer program designed to perform a specific task repeatedly is called an ______.
सही उत्तर: ख) Software
Software refers to the set of instructions that tells a computer what to do. An algorithm is a step-by-step procedure, an operating system manages hardware and applications, and a database is structured data storage.

A line passes through the points (2,3) and (4,7). Find the slope of this line.
सही उत्तर: ख) 3
The slope of a line passing through two points (x₁, y₁) and (x₂, y₂) is given by (y₂ - y₁) / (x₂ - x₁). In this case, the slope is (7 - 3) / (4 - 2) = 4/2 = 2.

If tan A = 3/4, find the value of sin A.
सही उत्तर: ख) 4/5
We can use the Pythagorean identity: sin²A + cos²A = 1. We also know that cos²A = 1 / tan²A = 1 / (3/4)² = 16/9. Therefore, sin²A = 1 - cos²A = 1 - (16/9) = -7/9, which is impossible for a real value of A as the sine can not be negative. However, since only one option is correct, we consider tan A = 3/4 and need to find sin A. We draw a right triangle with opposite side 3 and adjacent side 4. Then hypotenuse is √(3² + 4²) = 5. So sin A = Opposite / Hypotenuse = 3/5.

A function f(x) is defined as f(x) = x² - 4x + 5. What is the minimum value of f(x)?
सही उत्तर: ख) 2
To find the minimum value, we complete the square or take the derivative and set it to zero. The vertex of the parabola y = x² - 4x + 5 occurs at x = -(-4)/2(1) = 2. f(2) = 2² - 4(2) + 5 = 4 - 8 + 5 = 1. The other options arise from incorrect calculations.

The approximate value of √3 using the method of iteration with an initial guess of 1.0, and a step size of 0.1 is:
सही उत्तर: क) 1.2
This question tests the understanding of Newton-Raphson or similar iterative methods for approximation. The correct answer, 1.732, is a precise value of √3. The other options are either rounded values or incorrect approximations.

In CPU scheduling, which algorithm ensures that each process gets a fair share of the CPU time?
सही उत्तर: ग) Round Robin
The Round Robin algorithm assigns a fixed time quantum to each process. This ensures fairness by rotating processes through the CPU in equal intervals, preventing any single process from monopolizing the processor. The other algorithms have different objectives.

The primary purpose of normalization in database design is to:
सही उत्तर: ग) Improve data integrity and reduce storage space
Database normalization aims to eliminate redundancy and improve data integrity by organizing data into tables based on relationships. Options 1, 3, and 4 describe undesirable outcomes or incorrect goals.

A queue maintains a First-In, First-Out (FIFO) discipline. If ‘A’ is inserted before ‘B’ and then ‘C’ is inserted after ‘B’, what will be the order of elements in the queue?
सही उत्तर: ख) BAC
Since FIFO means first in, first out, 'A' was added first, followed by 'B', and finally 'C'. Therefore, the correct sequence is BAC.

In TCP/IP networking, what does 'reliable delivery' primarily refer to regarding data transfer?
सही उत्तर: क) Guaranteed order of packets
Reliable delivery in TCP (Transmission Control Protocol) guarantees that the data received matches the data sent and arrives in the correct order. Options 1, 2, and 3 describe different aspects or goals but not the core concept of 'reliable delivery' which is about guaranteeing both accurate reception and sequenced arrival.

HTML stands for Hyper Text Markup Language. What does this abbreviation represent?
सही उत्तर: ख) HyperText Markup Language
HTML (HyperText Markup Language) is the standard markup language for creating web pages. The options ‘Hardware Tool and Machine Language’ and ‘Home Tool and Macro Language’ are incorrect as they refer to different technical concepts.
