- Objective: Maintain price stability while supporting economic growth.
- Legal and Institutional Framework
- The RBI conducts monetary policy under the RBI Act, 1934.
- In 2016, the Act was amended to introduce the Flexible Inflation Targeting (FIT) framework.

About Repo Rate and Reverse Repo Rate
- The Repo Rate is the interest rate at which the Reserve Bank of India (RBI) lends short-term funds to commercial banks against government securities.
- It is a key monetary policy instrument used to regulate liquidity and credit flow in the economy.
- The Reverse Repo Rate is the interest rate at which RBI borrows funds from commercial banks, thereby absorbing excess liquidity from the banking system.
- Impact of Repo Rate Changes
- Increase in Repo Rate:
- Makes borrowing costlier for banks
- Reduces money supply and demand
- Helps control inflation
- Decrease in Repo Rate:
- Makes borrowing cheaper for banks
- Increases liquidity and credit flow
- Stimulates investment and economic growth
- Increase in Repo Rate:
Lead Poisoning

Context
- A recent study by Toxics Link found high levels of lead contamination in soil near lead-acid battery recycling units in Delhi-NCR. Soil samples showed contamination ranging from 100 ppm to 43,800 ppm, including areas near residential zones and schools.
About Lead Poisoning

Virtual Private Network (VPN)

Concept and Definition
- A Virtual Private Network (VPN) is a technology that establishes a secure digital connection between a user’s device and a remote server operated by a VPN provider.
- It creates an encrypted tunnel through which data is transmitted securely over the internet.
Key Features and Working Mechanism
- Encryption:
- VPN converts data into encrypted code, making it unreadable to unauthorised users.
- IP Address Masking:
- The user’s real IP address is hidden, and a new IP from the VPN server is used.
- Secure Tunnel:
- Establishes a point-to-point connection between the device and VPN server.
- Meaning of “VPN”:
- Virtual: No physical infrastructure; operates over the internet.
- Private: Ensures confidentiality of data and browsing activity.
- Networked: Connects multiple systems (user device and remote server).
Advantages of VPN
- Data Security: Protects sensitive data from cyber threats and interception.
- Privacy Protection: Prevents tracking by Internet Service Providers (ISPs) and third parties.
- Bypassing Restrictions: Enables access to blocked or restricted websites by masking location.
- Anonymity: Enhances online anonymity by hiding identity and browsing patterns.
Limitations and Concerns
- Misuse Potential: Can be used for bypassing legal restrictions or illegal activities.
- Dependence on Provider: Trust in VPN provider is critical, as they may have access to user data.
- Performance Issues: Encryption may reduce internet speed.
