The concept of ‘data bus’ in computer architecture refers to: (a) A system for transmitting data between the CPU and memory. (b) A physical cable connecting different computer components. (c) The software used to manage file storage. (d) The network interface card (NIC) that connects a computer to a network.
सही उत्तर: क) (a) A system for transmitting data between the CPU and memory.
The data bus is a crucial component for transferring information between the central processing unit (CPU) and memory. Option (b) describes cabling, (c) relates to file management software, and (d) concerns networking.

Which of the following best describes the primary function of an operating system? (a) To provide a user interface for applications. (b) To manage computer hardware and software resources. (c) To create and execute complex mathematical calculations. (d) To directly control all input devices.
सही उत्तर: ख) (b) To manage computer hardware and software resources.
The operating system manages the computer’s resources like CPU time, memory, and peripheral devices. Option (a) is a function of an application; (c) describes a calculator's function, and (d) is a specific function handled by device drivers.

Consider the following code snippet in Python: `x = [1, 2, 3]; y = x; y.append(4);`. What will be printed when you print `x` after this code executes?
सही उत्तर: ख) [1, 2, 3, 4]
The `append()` method modifies the list in-place. Since `y` is a reference to the same list as `x`, modifying `y` also changes `x`. Therefore, printing `x` will show the updated list [1, 2, 3, 4].

A computer system uses a 20-bit physical address and a page size of 4 KB. What is the maximum number of frames that can be present in a memory management unit (MMU)?
सही उत्तर: क) 16
The maximum number of frames is calculated by dividing the total physical address space by the page size. In this case, it's 20 bits / 12 bits (page size) = 1.67 which rounds up to 32. Options 16 and 64 are clearly lower than a 20-bit physical address, while 128 is an unlikely value for this configuration.

The process of converting high-level programming language code into machine code is called: Options: A. Compilation B. Interpretation C. Debugging D. Optimization
सही उत्तर: क) A. Compilation
Compilation involves translating source code into an executable form (machine code). Interpretation executes the code directly without a prior translation step.

What type of memory is RAM (Random Access Memory)? Options: A. Secondary Storage B. Cache Memory C. Primary Storage D. Constant Memory
सही उत्तर: क) A. Secondary Storage
RAM is classified as primary storage. It's volatile memory that the CPU directly accesses for immediate processing. Secondary storage (like hard drives) is non-volatile and used for persistent data storage.

What is the decimal equivalent of the binary number 101101? Options: A. 45 B. 51 C. 63 D. 69
सही उत्तर: क) A. 45
Converting binary 101101 to decimal: (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.
