Q221.Which is the smallest unit of memory/data in computer?
Correct Answer: A
A bit (binary digit) representing a 0 or a 1 is the absolute smallest unit of digital memory.
Q222.Which device is commonly used to copy a file from one computer to another?
Correct Answer: A
A USB Flash Drive (or pen drive) is a highly portable, non-volatile solid-state storage device used to transfer files between computers.
Q223.Which of the following is a volatile memory?
Correct Answer: D
Both RAM (Random Access Memory) and Cache memory are volatile, meaning their stored contents are completely erased when power is lost.
Q224.What is the function of a Hard Disk Drive (HDD)?
Correct Answer: C
A Hard Disk Drive (HDD) is a non-volatile magnetic secondary storage device used to store operating systems, programs, and user files long-term.
Q225.In AI, a 'heuristic' is best described as
Correct Answer: A
A heuristic is an approximate search technique or rule-of-thumb that directs problem-solving toward quick, optimal solutions rather than guarantees.
Q226.Which activation function outputs values between 0 and 1?
Correct Answer: C
The mathematical Sigmoid activation function squashes its inputs into a clean probability range between 0 and 1.
Q227.RAM is a ______ memory.
Correct Answer: B
RAM (Random Access Memory) is volatile primary memory, meaning it requires active electric currents to preserve its stored data.
Q228.Cache memory is located on ______?
Correct Answer: A
Cache memory is a small, ultra-fast static RAM (SRAM) unit located directly inside the CPU package to store frequently used data.
Q229.Which risk occurs when an LLM reveals sensitive information from its training or prompt data?
Correct Answer: A
Data leakage occurs when an AI model exposes private training data or confidential user inputs in its responses.
Q230.What is a system prompt usually used for?
Correct Answer: A
A system prompt is a high-level instruction used to establish the overall role, boundaries, tone, and security rules for the AI.
Q231.What is few-shot prompting?
Correct Answer: A
Few-shot prompting is a technique where a few sample tasks are demonstrated inside the prompt to teach the model how to perform a task.
Q232.What is zero-shot prompting?
Correct Answer: B
Zero-shot prompting relies on the model's pre-trained knowledge to perform a task directly from an instruction, with zero samples.
Q233.What is fine-tuning?
Correct Answer: A
Fine-tuning is the process of adjusting the weights of a pre-trained model by training it further on a smaller, domain-specific dataset.
Q234.What should you do after receiving an important factual answer from an LLM?
Correct Answer: B
Due to the risk of hallucinations, any critical or factual claim made by an LLM must be verified against primary sources before being relied upon.
Q235.Which of the following is an example of a permanent storage device?
Correct Answer: B
Hard disks (and SSDs) are non-volatile permanent storage devices, whereas RAM and DRAM are volatile temporary memories.
Q236.A printer is an example of what type of device?
Correct Answer: A
Printers and plotters produce permanent physical output on paper, which is classified as a hard copy.
Q237.Which of the following best describes 'reinforcement learning'?
Correct Answer: C
Reinforcement learning involves an agent interacting with an environment, learning to make decisions by maximizing cumulative rewards.
Q238.What does 'OCR' stand for in AI?
Correct Answer: C
OCR stands for Optical Character Recognition, a technology used to convert printed or handwritten text images into editable, machine-encoded text.
Q239.Which of the following represents a supervised learning task?
Correct Answer: D
Predicting numeric values (regression) or class labels using historical, labeled input-output pairs is a classic supervised learning task.
Q240.What is the main idea of 'few-shot learning'?
Correct Answer: B
Few-shot learning allows an AI model to recognize patterns or execute tasks after seeing only a very limited number of demonstrations.
