GK Questions

Time series forecasting models temporal patterns for demand prediction, anomaly detection, capacity planning.

Time series visualization: line charts show trends clearly, area charts emphasize volume. Both effective for temporal data analysis.

Data minimization limits collection to what's necessary for specified purpose. Reduces privacy risks, storage costs, breach impact.

Transparency (Explainable AI/XAI) ensures AI decisions can be interpreted by humans. Critical for trust, debugging, regulatory compliance.

Event-driven architecture uses message brokers for asynchronous, decoupled service communication. Enables scalability, resilience, real-time processing.

India's rapid 5G deployment driven by competitive telecom operators, government policy support, indigenous technology development. Critical for digital infrastructure questions.

Smart contracts are self-executing programs stored on blockchain that automatically enforce terms when conditions are satisfied. Used in DeFi, supply chain, insurance.

Blockchain records each transaction/transfer in immutable ledger, enabling end-to-end visibility of product journey. Used for food safety, luxury goods authentication.

Blockchain's immutability, transparency, decentralization make it suitable for land records management. Pilot projects in Andhra Pradesh, Telangana, Maharashtra use blockchain.

e₹ (e-Rupee) is RBI-issued digital token representing sovereign currency. Two types: retail (e₹-R) for public transactions, wholesale (e₹-W) for interbank settlements.

Differential Privacy mathematically guarantees that query results don't reveal individual records. Used in census data, health analytics, tech company telemetry.

Zero Trust implements: identity verification, least privilege, micro-segmentation, continuous monitoring. Assumes no implicit trust based on network location.

PMP (PMI) covers traditional project management; PRINCE2 is process-based; Agile/Scrum certifications focus on iterative delivery. All valued for tech project leadership.

Chaos Engineering (Netflix Chaos Monkey) proactively tests system resilience by injecting failures in controlled experiments. Builds confidence in fault tolerance.

GitOps (ArgoCD, Flux) declaratively defines desired state in Git; operators sync cluster state. Benefits: audit trail, rollback via git revert, peer review via PRs.

IaC (Terraform, Ansible, CloudFormation) defines infrastructure in declarative code, enabling version control, peer review, automated testing, consistent deployments.

Adapter/ACL patterns wrap external APIs, translating between internal models and external interfaces. Critical for maintainable integrations and testing.

Sharding partitions data horizontally across nodes based on key ranges or hashes, enabling horizontal scaling. Critical for handling large datasets in distributed databases.

Edge computing brings computation to network edge (routers, gateways), enabling real-time processing for IoT, autonomous vehicles, industrial automation. Complements cloud.

Machine Learning enables systems to learn patterns from data and improve performance on tasks without explicit programming. Types: supervised, unsupervised, reinforcement.
