Answer: Antarctic Desert

The Antarctic Desert is the largest desert in the world, covering about 14 million square kilometers. Deserts are defined by low precipitation (less than 250mm annually), not just sand, making Antarctica the largest cold desert.

Answer: PSLV

Answer: False

NEFT (National Electronic Funds Transfer) settles transactions in half-hourly batches, not real-time. RTGS (Real-Time Gross Settlement) processes high-value transactions individually in real-time.

Answer: Principle, Privilege

Principle of Least Privilege (PoLP) restricts user/system access rights to only what is essential for their role, minimizing damage from accidents or attacks. Implemented via role-based access control (RBAC), regular access reviews, and just-in-time permissions. Core concept in secure system design.

Answer: INSAT/GSAT

INSAT and GSAT series communication satellites provide DTH broadcasting, telecommunication, and weather monitoring services. INSAT-4A, GSAT-15, GSAT-24 carry transponders leased to DTH providers like Dish TV, Tata Play. These geostationary satellites ensure continuous coverage over Indian subcontinent.

Answer: False

Big Data is defined by 5 Vs: Volume (scale), Velocity (speed of generation), Variety (structured/unstructured data), Veracity (uncertainty/quality), and Value (actionable insights). Handling Big Data requires distributed computing (Hadoop, Spark), advanced analytics, and scalable storage solutions.
