In the context of programming languages, what does ‘variable’ represent? (a) A fixed value that cannot be changed. (b) An identifier that holds a storage location in memory where data can be stored and retrieved. (c) A command for executing a specific task. (d) The operating system used to run the program.
सही उत्तर: ख) (b) An identifier that holds a storage location in memory where data can be stored and retrieved.
A variable is indeed an identifier for a memory location, allowing dynamic storage of information. Option (a) defines a constant, (c) refers to a function call and (d) describes the OS.

A computer network where devices are connected through a central switch or hub is known as: (a) Bus Topology (b) Ring Topology (c) Star Topology (d) Mesh Topology
सही उत्तर: ग) (c) Star Topology
Star topology is the correct answer because it describes a network structure where all devices connect directly to a central switch or hub. A bus topology involves connecting devices along a single cable, a ring requires a closed loop, and a mesh topology has redundant connections.

Which of the following is a key characteristic of a client-server network architecture?
सही उत्तर: ख) B. One or more dedicated servers provide services to multiple clients
In a client-server model, one or more powerful servers centralize resources and handle requests from client devices (like computers or smartphones). This contrasts with fully decentralized networks where all devices are equal. Options A and C describe different network models, and D refers to a specific type of connection.

In binary code, the number 1011 represents which decimal value?
सही उत्तर: घ) D. 10
To convert binary 1011 to decimal, we calculate: (1 * 2^3) + (0 * 2^2) + (1 * 2^1) + (1 * 2^0) = 8 + 0 + 2 + 1 = 11. Options A and B are incorrect calculations. Option D is also wrong.

The process of converting analog signals into digital data is known as:
सही उत्तर: ग) C. Digitalization
Demodulation is the specific term for transforming an analog signal (like audio or video) into a digital representation that a computer can understand and process. Modulation is the opposite process, encoding refers to converting data into a format suitable for transmission, and digitization is a more general term.

Which of the following statements best describes the primary function of RAM (Random Access Memory)?
सही उत्तर: ख) B. To temporarily store data that the CPU is actively using
RAM's main purpose is to hold data and instructions that the computer’s processor needs immediate access to. This allows quick reading and writing of information, crucial for running programs efficiently. Options A (permanent storage) and C (long-term file storage) are incorrect; RAM is volatile. Option D describes a cache memory.

In MS Excel, the function `=SUM(A1:A5)` would calculate the sum of values in which range?
सही उत्तर: ख) B. Cells A1 to A5
The `SUM` function in Excel, when given a range like `A1:A5`, calculates the sum of all numerical values within that specified cell range. Options A and C are incorrect because they specify different ranges. Option B accurately reflects how the function operates with the given range.
