In the context of computer storage, what distinguishes a ‘Solid State Drive (SSD)’ from a traditional ‘Hard Disk Drive (HDD)?’
सही उत्तर: ख) B. HDDs are faster and more durable than SSDs
The key difference is the technology used: HDDs use rotating magnetic platters while SSDs employ flash memory for data storage. This fundamental difference explains the performance variations described in the other options.

Which data structure uses a linked list to store elements where each element points to the next?
सही उत्तर: घ) Linked List
A Linked List is defined by its structure – elements are connected through pointers, referencing the next element in the sequence. Arrays are contiguous and fixed-size, stacks and queues use different underlying data structures.

Which of the following operations is NOT commonly associated with relational database management systems (RDBMS)?
सही उत्तर: घ) D. Data Integrity Constraints
File system management isn’t a core function of an RDBMS; it deals with organizing files on storage devices, while the other options (normalization, SQL queries and constraints) are fundamental to how RDBMSs operate.

The term 'RAM' stands for which of the following?
सही उत्तर: ग) C. Rapid Application Module
RAM (Random Access Memory) is a type of volatile memory that allows data to be accessed directly at any location in the address space, providing fast read and write speeds for immediate data processing which aligns with the definition.

What is the fundamental unit of information storage and retrieval in computers?
सही उत्तर: ख) B. Bit
A bit (Binary Digit) is the smallest unit of data, representing either a 0 or a 1. The other options represent larger units of measurement - pixels are for images, bytes are groups of bits and kilobytes are groups of bytes. This aligns with basic computer science principles.

-
Which bitwise operation performs logical AND between two bits?
सही उत्तर: ग) C) AND
Option C is the correct answer. The AND operator returns 1 only if both input bits are 1; otherwise, it returns 0. OR, NOT and XOR perform different bitwise logical operations.

What is the purpose of a ‘cache’ memory?
सही उत्तर: क) A) To store infrequently accessed data for faster retrieval
Option A correctly describes the function of cache memory. It's a small, fast memory used to hold frequently accessed data, reducing access times compared to main memory (RAM). The other options describe different types of memory or their roles.

In computer networking, what does ‘bandwidth’ measure?
सही उत्तर: ख) B) The rate at which data can be transmitted over a connection
Option B is correct. Bandwidth quantifies the capacity of a transmission medium, representing the amount of data that can pass through it in a given time period (typically measured in bits per second). The other options relate to different aspects of networking.
