Which of the following is a characteristic feature of a 'distributed operating system'? (a) A single processor handles all tasks. (b) Processing is performed by multiple interconnected computers. (c) It relies entirely on a centralized database server. (d) It requires specialized hardware for optimal performance.
सही उत्तर: ख) (b) Processing is performed by multiple interconnected computers.
A distributed operating system involves dividing tasks among several computers that communicate with each other, making it a key difference from a single-processor system. (a) is the opposite; (c) describes a client-server model, and (d) isn't necessarily required.

In computer networking, what does 'IP address' represent? (a) A physical address of a network device. (b) A logical address that uniquely identifies a device on a network. (c) The bandwidth of the network connection. (d) The encryption key for secure communication.
सही उत्तर: ख) (b) A logical address that uniquely identifies a device on a network.
An IP (Internet Protocol) address is a unique numerical label assigned to each device connected to a computer network, enabling data to be routed between them – it's a logical identifier. (a) describes a MAC address; (c) bandwidth and (d) encryption keys.

Which of the following best describes the primary function of a compiler? (a) To directly execute instructions. (b) To translate high-level programming languages into machine code. (c) To manage computer memory. (d) To create graphical user interfaces.
सही उत्तर: ख) (b) To translate high-level programming languages into machine code.
A compiler converts human-readable source code (like C++ or Java) into equivalent machine code that the processor can directly execute. Option (a) is incorrect because execution is the role of the CPU; (c) relates to memory management and (d) to UI design.

In Boolean algebra, if A + A·B is simplified, the result is:
सही उत्तर: घ) A + B
The expression A + A·B can be simplified using the distributive property: A + AB. Therefore, 'A + AB only' is the correct answer. The other options are incorrect because they either leave terms unsimplified or result in an incorrect simplification.

In the context of computer networks, what does 'bandwidth' primarily measure?
सही उत्तर: ख) The maximum data transfer rate over a network connection
Bandwidth represents the capacity of a network connection – specifically, how much data can be transmitted per unit of time (e.g., bits per second). The other options relate to different aspects of networking.

The process of converting data from one format to another without losing information is called:
सही उत्तर: ग) Encoding
Encoding refers to transforming data into a different representation (like ASCII or Unicode) while maintaining its original meaning. Encryption focuses on security, compression reduces file size, and hashing produces a unique fixed-size string based on the input data.

Consider the following binary number: 101101. What is its equivalent in decimal?
सही उत्तर: ख) 35
To convert 101101 (binary) to decimal, we perform the calculation: (1 * 2^5) + (0 * 2^4) + (1 * 2^3) + (1 * 2^2) + (0 * 2^1) + (1 * 2^0) = 32 + 0 + 8 + 4 + 0 + 1 = 45. Thus, the decimal equivalent is 45.

What does RAM stand for, commonly used in computer systems?
सही उत्तर: क) Random Access Memory
RAM stands for Random Access Memory. This is the primary memory of a computer where data is stored for immediate access by the processor. The other options are not standard definitions of RAM.
