Part III — Indian Economy & General Science

Chapter 4: Economy, Computers and Science & Technology

4.1 Indian Economy Basics

India's central bank, the Reserve Bank of India (RBI), was established in 1935 and is responsible for monetary policy, currency issuance, and banking regulation. GDP (Gross Domestic Product) measures the total value of goods and services produced within a country's borders in a given period. India's economy is broadly divided into the primary sector (agriculture, mining), secondary sector (manufacturing, industry), and tertiary sector (services) — the services sector is the largest contributor to India's GDP. Inflation is measured via the Consumer Price Index (CPI) and Wholesale Price Index (WPI). The Union Budget is presented annually, typically on 1 February, by the Finance Minister.

4.2 Banking Awareness

Scheduled Commercial Banks in India include Public Sector Banks, Private Sector Banks, and Foreign Banks, alongside Regional Rural Banks (RRBs) and Cooperative Banks. The Repo Rate is the rate at which the RBI lends short-term funds to commercial banks; the Reverse Repo Rate is the rate at which the RBI borrows from commercial banks. NPA (Non-Performing Asset) refers to a loan/advance where the borrower has stopped making interest or principal repayments for a specified period (generally 90 days).

4.3 Basic Computer Applications

Hardware refers to physical computer components (CPU, RAM, storage, input/output devices); software refers to programs and instructions. RAM (Random Access Memory) is volatile memory used for temporary data during processing, while ROM (Read-Only Memory) is non-volatile memory retaining data without power. Common operating systems include Windows, Linux (open-source), and macOS. The Internet is a global network of interconnected computer networks, while the World Wide Web (WWW) is a system of interlinked hypertext documents accessed via the internet.

4.4 General Science

Newton's Laws of Motion, the periodic table (organising chemical elements by atomic number), and basic biology (cell structure, human body systems) form core General Science topics. Photosynthesis is the process by which green plants convert light energy into chemical energy (glucose), using carbon dioxide and water, releasing oxygen as a byproduct. DNA (Deoxyribonucleic acid) carries genetic information in living organisms.
