ICT means Information and Communication Technology. It is an umbrella term covering digital tools used to store, process, transmit and exchange information. Core components include hardware, software, networks and data/content.

A useful broad timeline is: computerisation → liberalisation/IT growth → Internet age → mobile/broadband era → Digital India and AI-oriented programmes.

ICT supports e-governance portals, online grievance systems, digital payments, online education, telemedicine, agricultural markets, digital records and electronic court services.

e-Governance is the use of ICT to deliver public information/services, improve internal government efficiency and enable citizen participation. Common models are G2C, G2B, G2G and G2E.

• Faster service delivery
• Greater transparency and accountability
• Reduced paperwork and avoidable delays
• Better information access
• Improved monitoring and coordination

Digital divide, low digital literacy, infrastructure gaps, cybersecurity, privacy, interoperability and resistance to organisational change can limit e-governance outcomes.

A Management Information System collects, processes, stores and distributes information to support management decisions and control. Its core components can be remembered as people, data, hardware, software and procedures.

The Digital India Programme was launched on 1 July 2015. Its broad vision includes digital infrastructure as a utility, governance/services on demand and digital empowerment of citizens. The programme is associated with major digital public infrastructure and service initiatives.

BharatNet is the major rural broadband/optical-fibre connectivity project, originally launched as the National Optical Fibre Network and renamed BharatNet. PM-WANI is a public Wi-Fi framework launched in 2020 to expand affordable public Wi-Fi through public data offices and related entities.

DPI refers to population-scale, interoperable digital systems that can support public and private services. In exam preparation, Aadhaar, UPI and DigiLocker are commonly used examples of India's digital public infrastructure ecosystem.

Cloud computing delivers computing resources such as storage, servers, databases and software over networks. IaaS provides infrastructure, PaaS provides a platform, and SaaS provides software. MeghRaj is the Government of India's GI Cloud initiative for government cloud use.

Remember the broad evolution: 1G voice → 2G SMS/basic data → 3G mobile Internet → 4G high-speed broadband → 5G high speed/low latency and IoT-oriented capabilities. TRAI is India's telecom regulatory authority.

Agriculture: e-NAM. Education: DIKSHA, SWAYAM, e-Pathshala. Health: eSanjeevani, ABDM/e-Hospital. Judiciary: e-Courts and NJDG. Police: CCTNS. Payments: UPI/BHIM. Documents: DigiLocker.

Aadhaar is a 12-digit identity number issued by UIDAI. DigiLocker is a digital document platform. BHIM is a mobile payment app based on UPI and was launched in December 2016.

NKN connects research and higher-education institutions. The National Supercomputing Mission develops high-performance computing capability; the PARAM family is strongly associated with India's supercomputing programme.

As government systems become interconnected, cybersecurity becomes essential for protecting citizen data and critical services. Important institutions include CERT-In, NCIIPC and I4C. The IT Act and related rules form part of the legal framework.

Match the initiative with its purpose + institution + year. Avoid learning programme names without their function.

If a question asks who regulates telecom → TRAI. who responds to cyber incidents → CERT-In. critical information infrastructure → NCIIPC. cybercrime coordination → I4C. rural fibre connectivity → BharatNet. public Wi-Fi framework → PM-WANI. government cloud → MeghRaj.
