Technology – Hard Level – GK Questions

Q: The technology that uses biological molecules like DNA for data storage is called ________ Computing.

Bio-molecular / DNA – DNA data storage encodes digital information into synthetic DNA strands, offering extreme density (exabytes/gram) and longevity (thousands of years). Challenges: slow read/write speeds and high costs. Research by Microsoft, IITs, and startups. Represents convergence of biology and information technology for archival storage.

Q: Which emerging computing paradigm processes data near the source to reduce latency for IoT applications?

Fog Computing – Fog Computing extends cloud capabilities to network edge (routers, gateways), enabling real-time processing for IoT, autonomous vehicles, and industrial automation. Reduces latency, bandwidth usage, and enhances privacy. Complements cloud (centralized) and edge (device-level) computing. Critical for distributed systems questions.

Q: Brain-Computer Interfaces (BCIs) can currently enable paralyzed patients to control robotic limbs using thoughts alone.

True – Invasive BCIs (like Neuralink, Synchron) have enabled paralyzed individuals to control cursors, robotic arms, and communicate via thought in clinical trials. Non-invasive BCIs (EEG) offer limited control. Challenges: signal resolution, surgical risks, and long-term stability. Represents frontier of neurotechnology and assistive devices.

Q: Artificial General Intelligence (AGI) currently exists and is widely deployed in commercial applications.

False – AGI (human-level AI that can learn and perform any intellectual task) does not yet exist. Current AI systems are Narrow AI, designed for specific tasks. AGI remains a research goal with significant technical and ethical challenges to overcome.

Q: Which attack involves overwhelming a server with traffic to make it unavailable to legitimate users?

DDoS – DDoS (Distributed Denial of Service) attack uses multiple compromised systems to flood a target server with traffic, exhausting resources and making services unavailable. Mitigation includes traffic filtering, rate limiting, and using DDoS protection services.

Q: Blockchain technology can only be used for cryptocurrencies like Bitcoin.

False – Blockchain has diverse applications beyond cryptocurrency: supply chain tracking, digital identity, voting systems, healthcare records, land registries, and smart contracts. Its core value is providing decentralized, tamper-proof, transparent record-keeping.

Q: Which technology uses quantum mechanical phenomena like superposition and entanglement for computation?

Quantum Computing – Quantum Computing uses qubits that can exist in superposition (0 and 1 simultaneously) and entanglement (correlated states) to solve certain problems exponentially faster than classical computers, with applications in cryptography, drug discovery, and optimization.

Q: The technology that enables machines to learn from data without being explicitly programmed is called ________ Learning.

Machine – Machine Learning is a subset of Artificial Intelligence where algorithms improve automatically through experience and data. It includes supervised, unsupervised, and reinforcement learning approaches used in recommendation systems, fraud detection, and more.
