Technology – MCQ – GK Questions

Oracle manipulation feeds false prices to DeFi protocols, triggering incorrect liquidations or arbitrage. Critical vulnerability requiring decentralized, robust oracles.

Aditya-L1 positioned at Sun-Earth L1 point for uninterrupted solar observation. Studies coronal heating, CMEs, solar flares.

Neuromorphic chips excel at processing sparse, event-driven data from sensors: vision, audio, IoT. Critical for edge AI with low power budgets.

Resilience patterns: self-healing replaces failed instances, circuit breaker prevents cascading failures, retry logic handles transient errors.

Programs under Digital India promote rural startups: CSCs for service delivery, agri-tech incubators. Critical for inclusive innovation.

Yield farming/liquidity mining rewards users with tokens for providing liquidity to DEX pools. Critical DeFi incentive mechanism with impermanent loss risks.

Neuromorphic chips use spiking neurons that fire only when needed, and event-driven computation that processes only changes. Critical for edge AI efficiency.

Data drift: input feature distribution changes; concept drift: relationship between features and target changes. Monitoring both enables timely model retraining.

DeFi risks: smart contract bugs enable fund theft, oracle manipulation feeds false prices, impermanent loss affects liquidity providers. Critical for DeFi security understanding.

Neuromorphic chips achieve orders-of-magnitude better energy efficiency by mimicking brain's event-driven, sparse computation. Critical for edge AI and sustainable computing.

Adversarial training includes adversarial examples in training data; defensive distillation smooths model outputs. Both improve robustness against adversarial attacks.

Uniswap uses automated market maker (AMM) model with liquidity pools instead of order books. Enables permissionless token trading with constant product formula.

Renewable integration combines SCADA for control, IoT sensors for real-time data, AI forecasting for generation prediction. Critical for grid stability with high renewable penetration.

Shukrayaan-1 is India's planned Venus orbiter mission (target launch ~2028) to study the planet's thick atmosphere, surface processes, and solar wind interactions.

Neuromorphic chips (Intel Loihi, IBM TrueNorth) use spiking neural networks and event-driven processing for orders-of-magnitude better energy efficiency than GPUs for AI tasks.

Shor's Algorithm factors integers in polynomial time on quantum computers, breaking RSA which relies on factoring difficulty. Requires fault-tolerant quantum computers not yet available.

Adversarial examples add imperceptible perturbations to inputs that cause ML models to misclassify. Critical vulnerability for computer vision, NLP systems requiring robust defenses.

Active-active architecture runs full workload in multiple regions simultaneously, enabling instant failover with zero RPO/RTO. Critical for mission-critical systems requiring maximum resilience.

UMANG (Unified Mobile Application for New-age Governance) is a single app providing access to 1,200+ central and state services: Aadhaar, PAN, EPFO, utilities, education, health. Features: multilingual support, voice search, offline access. MyGov is for engagement; DigiLocker for documents; UMANG for service delivery.

Inkjet printers spray tiny ink droplets without physical contact with paper (non-impact). Laser printers use toner and electrostatic charges. Impact printers (Dot Matrix, Daisy Wheel, Line) strike ribbon against paper, producing noise but capable of multi-part forms. Inkjet/Laser dominate home/office use.
