GK Questions

Disabling SSID broadcast hides network name from public scans, adding obscurity layer. However, strong security requires WPA3 encryption, complex password, MAC filtering, and regular firmware updates. WEP is broken; default passwords are easily guessable; open networks offer no protection.

Static IP is manually configured and remains constant, used for servers, printers, remote access. Dynamic IP is assigned by DHCP server and may change on reboot/lease expiry, typical for home users. Static IPs cost more but provide reliability for services requiring consistent addressing.

UPI AutoPay enables mandate-based recurring payments for subscriptions (OTT, utilities, mutual funds). Users set amount, frequency, and validity; payments execute automatically without manual intervention each time. Enhances convenience while maintaining security with transaction limits and notifications.

F5 or Ctrl+R refreshes/reloads the current webpage to fetch latest content from server. Ctrl+F5 performs hard refresh bypassing cache. These shortcuts improve productivity when checking for updated information or troubleshooting loading issues.

Real-time translation combines: Speech Recognition (audio to text), NLP (translation between languages), and Speech Synthesis (text to audio). Advanced systems also use context understanding and lip-sync for natural output. Used in global collaboration tools and accessibility features.

Vikram lander (Chandrayaan-3) honors Dr. Vikram Sarabhai, father of India's space program. The rover was named 'Pragyan' (wisdom). Successful landing on Aug 23, 2023 made India the 4th nation to soft-land on Moon and first near south pole.

AES-256 (Advanced Encryption Standard with 256-bit key) is approved by NIST for top-secret information. Provides strong security against brute-force attacks. DES/3DES are deprecated; RC4 has known vulnerabilities. AES is efficient in both hardware and software implementations.

PAHAL (Pratyaksh Hanstantrit Labh) is the DBT scheme for LPG subsidies, accessible via MyLPG app. Enables direct subsidy transfer to bank accounts, reducing leakage and ensuring benefits reach genuine beneficiaries.

FAME provides demand incentives for EVs and charging infrastructure. Phase-II focuses on public transport and shared mobility.

UEBA uses ML to establish behavioral baselines and detect anomalies indicating compromised accounts or insider threats.

Multimodal models (CLIP, LLaVA) process text, images, audio jointly, enabling visual question answering, image captioning, and cross-modal retrieval.

Code LLMs (Codex, CodeLlama) trained on code repositories enable natural language to code generation. Combined with fine-tuning and prompt engineering for developer productivity tools.

Transparent tracking from origin to consumer.

P2P/P2M transactions with QR codes, offline mode.

Critical for net-zero pathways and climate mitigation.

Regional navigation satellite system with 7 satellites.

Intended use, training data, evaluation metrics, limitations.

Adds statistical noise to protect individuals in aggregate data.

Critical for cloud security posture management.

Least privilege, micro-segmentation, monitoring.
