Q1341. Given below are two statements regarding digital legislation in India. Statement I: The IT Act 2000 amended the Indian Penal Code and the Indian Evidence Act to recognize electronic records. Statement II: The Digital Personal Data Protection Act, 2023 (DPDP Act) has now overridden certain data protection clauses previously governed loosely under the IT Act. Which of the above statement(s) is/are correct?
Explanation
The IT Act, 2000 fundamentally changed the Indian legal landscape by amending other laws like the Evidence Act to recognize electronic records. More recently, the Digital Personal Data Protection Act of 2023 has introduced a more modern and comprehensive framework for data privacy, superseding older, less specific clauses in the IT Act. Both legislations are critical for India’s.

Q1342. Match List I with List II.
Section of IT Act
Provision
A. Section 43
i. Tampering with computer source documents
B. Section 65
ii. Penalty for damage to computer/computer system
C. Section 66B
iii. Power to issue directions for interception/ monitoring
D. Section 69
iv. Punishment for dishonestly receiving stolen computer resource
Explanation
The IT Act organizes legal provisions by section: Section 43 handles damage to systems, Section 65 deals with tampering with source documents, Section 66B punishes receiving stolen resources, and Section 69 gives power for interception for national security. This structured approach allows for the precise prosecution of various digital crimes, ensuring that the legal system can effectively.

Q1343. Which of the following traditional offenses is generally NOT addressed or prosecutable under the core provisions of the IT Act, 2000?
Explanation
The IT Act, 2000 is specifically designed to address crimes involving digital data and electronic communication, such as hacking, publishing child abuse material, or launching DDoS attacks. These are "cyber" crimes. The physical theft of computer hardware, however, is a traditional property crime covered under the Indian Penal Code, not the IT Act, as it involves.

Q1344. What is the most appropriate legal effect of the IT Act, 2000 on digital signatures?
Explanation
The Information Technology Act, 2000 provided the essential legal framework for electronic governance in India by granting digital signatures the same legal status as traditional handwritten signatures. This recognition ensures that electronic records and documents authenticated via digital signatures are legally binding. Consequently, this legislation paved the way for secure online transactions, electronic filing, and the growth of e-commerce.

Q1345. How does Augmented Reality (AR) fundamentally differ from Virtual Reality (VR)?
Explanation
Augmented Reality enhances the real world by overlaying digital information, such as images or data, onto a user’s view of their physical surroundings. Virtual Reality, however, creates a completely immersive, computer-generated environment that replaces the real world entirely. While AR integrates digital elements into the existing environment, VR transports the user to an entirely different, simulated space.

Q1346. Consider the following concepts related to Quantum Computing: I. Qubits (Quantum bits) can exist in multiple states simultaneously due to superposition. II. Entanglement allows qubits that are separated by distance to interact instantaneously. III. Quantum computers perform calculations identically to classical binary computers, just faster. IV. Quantum computing poses a future threat to current cryptographic standards (like RSA). V. Decoherence is a major challenge in maintaining quantum states. Which of the above statement(s) is/are correct?
Explanation
Quantum computing utilizes qubits that can exist in multiple states simultaneously due to superposition and interact via entanglement. These systems perform calculations fundamentally differently from classical computers, posing a significant future threat to current encryption standards like RSA. While powerful, quantum computers face the major challenge of decoherence, where external interference disrupts the fragile quantum states needed for.

Q1347. Identify the incorrect statement regarding the "Metaverse."
Explanation
The Metaverse is envisioned as a decentralized network of interconnected 3D virtual worlds where users can interact socially and economically. It often incorporates technologies like VR, AR, and blockchain-based digital assets. It is not owned or controlled by any single government or corporation; instead, it is expected to be a collaborative ecosystem developed by many different.

Q1348. A surgeon uses a specialized headset during an operation that projects real-time 3D MRI scans precisely over the patient’s body, and the surgeon can interact with these holograms. This is an application of:
Explanation
Mixed Reality is a technology that blends the physical and digital worlds, allowing real and virtual objects to coexist and interact in real-time. A surgeon using a headset to project and interact with 3D MRI scans over a patient’s body is a prime example. Unlike pure VR, MR keeps the user connected to the real environment while.

Q1349. In the context of quantum computing, the term "Quantum Supremacy" refers to:
Explanation
Quantum Supremacy is a milestone in computer science reached when a quantum computer performs a specific calculation that is practically impossible for the most powerful classical supercomputer to complete in a reasonable timeframe. This achievement demonstrates the fundamental power of quantum mechanics to solve certain types of complex problems far more efficiently than traditional binary-based computing architectures.

Q1350. The technology that involves constructing a three-dimensional solid object from a digital file by successively adding material layer by layer is known as:
Explanation
3D printing, also known as additive manufacturing, is a process that creates three-dimensional solid objects by adding material layer by layer from a digital file. This is the opposite of traditional subtractive manufacturing, which involves cutting away material. 3D printing allows for the creation of complex shapes and customized parts, revolutionizing prototyping, manufacturing, and even medical.
