Information Technology: Computing, Internet, and Cyber Security

India's IT sector ($254B revenue, 5.4M employees) drives digital transformation. Computing: cloud, edge, HPC (PARAM series), semiconductor (PLI Rs 76,000 cr, DLI). Internet: 900M+ users, BharatNet, 5G, 6G testbed. Cyber security: CERT-In, NCIIPC, IT Act 2000, DPDP Act 2023, critical infrastructure protection. Emerging: AI, quantum, blockchain in security.[TOPIC CLASSIFICATION]

[EXAMINER REASONING]

1. Trap: Confusing IT Act 2000 (amended 2008) with DPDP Act 2023. IT Act covers cyber crimes, digital signatures, intermediaries; DPDP Act covers personal data protection. Many aspirants think DPDP replaced IT Act.
2. Most confused: Cyber security architecture: CERT-In (operational), NCIIPC (critical infrastructure), NCCC (threat monitoring), Sectoral CERTs. Many aspirants don't know the hierarchy. Also, CERT-In directions (2022) on incident reporting (6 hours) and log retention.
3. Key anchor: Digital India pillars: broadband highways, universal mobile, public internet, e-governance, e-Kranti, information for all, electronics manufacturing, IT for jobs, early harvest. Semiconductor Mission (PLI Rs 76,000 cr, DLI). 5G launch (Oct 2022), 6G testbed (2023).
4. Current affairs hook: DPDP Act 2023 (notified, rules draft 2024). CERT-In 6-hour incident reporting (2022). IndiaAI Mission (Rs 10,372 cr). Semiconductor PLI (Rs 76,000 cr) - Micron, Tata, CG Power. 5G: 4L+ base stations. 6G: Bharat 6G Mission. Cyber crimes rising (NCRB).
5. Mains hinge: Evaluate: Is India's cyber security framework adequate for a $1T digital economy? The CERT-In overreach vs security, data localization vs innovation, and the talent gap (1M+ cyber jobs) are the Mains tensions.

Core Concept

IT Sector: $254B revenue (FY24), 5.4M employees, 7.5% GDP. Exports $194B. Digital India (2015): 9 pillars. BharatNet: 2.5L GPs, optical fiber. 5G launch Oct 2022, 4L+ base stations (2024). 6G: Bharat 6G Mission, testbed 2023, target 2030.

Semiconductor: India Semiconductor Mission (PLI Rs 76,000 cr, DLI). Fab: Micron (Gujarat), Tata (Assam), CG Power. Design: DLI scheme. ATMP: OSAT units.

HPC: PARAM series (C-DAC), PARAM Siddhi-AI (5.27 petaflops). AIRAWAT (AI supercomputer).

Internet: 900M+ users (2024), 5G 4L+ sites, 6G testbed. Digital Public Infrastructure: Aadhaar, UPI, DigiLocker, ABDM, ONDC.

Cyber Security: IT Act 2000 (amended 2008) - cyber crimes, digital signatures, intermediaries. DPDP Act 2023 - personal data protection, consent, fiduciary duties, penalties. CERT-In (operational, 6-hour reporting), NCIIPC (critical infra), NCCC (threat monitoring), Sectoral CERTs (Finance, Power, etc.). Critical Information Infrastructure (CII) protection. Data localization debates. Ransomware, phishing, supply chain attacks rising.
