General Science & Computer Applications

📖 Core science and computing basics

• General science — basics of physics, chemistry and biology at a school level.
• Computer fundamentals — hardware, software, operating systems, internet basics.
• Office applications — MS Office suite, email, and government e-governance tools relevant to EPFO's digital operations (e.g. UAN, EPFO portal).

🚀 Space technology

India's space programme has evolved from early sounding-rocket experiments to a full-fledged capability spanning launch vehicles, satellites and interplanetary missions. Key achievements include the PSLV and GSLV launch vehicle families, the Chandrayaan lunar missions, Mangalyaan (Mars Orbiter Mission), and human spaceflight preparation under Gaganyaan. India runs distinct satellite programmes for different purposes: INSAT/GSAT for communication, IRNSS (NavIC) for regional navigation, and the IRS (Indian Remote Sensing) series for earth observation. Satellites also support defence applications (surveillance, secure communication) and EDUSAT-style educational/academic broadcasting.

🛰️ Institutions: ISRO and DRDO

ISRO (Indian Space Research Organisation) is India's civilian space agency, running the country's launch vehicle and satellite programmes end-to-end. DRDO (Defence Research and Development Organisation) is India's defence research agency, with a vision and mission centred on achieving self-reliance in critical defence technologies — missiles, radar, electronic warfare systems, and materials — reducing dependence on imported defence equipment.

💻 Information and Communication Technology (ICT)

ICT's nature and scope spans its transformative role in day-to-day life (digital payments, communication, information access) and in industry (automation, digital supply chains, e-commerce). Government has promoted ICT adoption through various schemes — Digital India, BharatNet (rural broadband), and sector-specific digitisation programmes — aiming to widen digital access and literacy.
