GK Questions

Answer: Kaziranga

Kaziranga National Park in Assam is home to the world's largest population of the Indian one-horned rhinoceros (over 2,600). It is a UNESCO World Heritage Site and also shelters tigers, elephants, wild water buffalo, and swamp deer.

Answer: Igneous

Igneous rocks are formed by the cooling and solidification of magma or lava. Examples include granite (intrusive, cooled slowly underground) and basalt (extrusive, cooled quickly on surface). Sedimentary rocks form from deposition, while metamorphic rocks form under heat and pressure.

Answer: Rice

Rice is a Kharif crop, sown at the beginning of the Southwest Monsoon (June-July) and harvested in September-October. Kharif crops depend on monsoon rainfall, while Rabi crops like wheat are grown in winter with irrigation.

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

The Polar Satellite Launch Vehicle (PSLV) is ISRO's workhorse rocket, primarily used for launching earth observation and remote sensing satellites into polar and sun-synchronous orbits. It has successfully launched missions like Chandrayaan-1 and Mangalyaan.

Answer: Damodar

The Damodar River is called the 'Sorrow of Bengal' because of its frequent flooding in the past, which caused widespread destruction in West Bengal. The Damodar Valley Corporation was established in 1948 to control these floods through dams and reservoirs.

Answer: RAM

RAM (Random Access Memory) is volatile memory that loses stored data when power is turned off. Used for temporary storage of actively running programs and data. Non-volatile memories (ROM, EEPROM, Flash) retain data without power, used for firmware, storage, and configuration settings.

Answer: World Wide Web

WWW (World Wide Web) is an information system where documents and resources are accessed via internet using URLs and hyperlinks. Invented by Tim Berners-Lee in 1989. Web pages are written in HTML, transmitted via HTTP/HTTPS, and displayed by web browsers. Web is a service running on the internet infrastructure.

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: GPS

GPS (Global Positioning System) uses signals from 24+ satellites to determine precise geographic location (latitude, longitude, altitude) anywhere on Earth. Integrated into smartphones for navigation, ride-hailing, fitness tracking. Works outdoors; assisted by Wi-Fi/cell towers indoors for faster acquisition.

Answer: Deque

Deque (Double-Ended Queue) allows insertion and deletion at both front and rear ends, combining features of stack (LIFO) and queue (FIFO). Implemented using arrays or linked lists. Used in palindrome checking, sliding window problems, and browser history management. Time complexity: O(1) for end operations.

Answer: Encryption

Encryption transforms plaintext into ciphertext using algorithms and keys, ensuring only authorized parties with decryption key can read the data. Protects data at rest (stored) and in transit (transmitted). Hashing is one-way for integrity; encoding (Base64) is not security; compression reduces size.

Answer: NFS

NFS (National Financial Switch) is NPCI's largest ATM network in India, enabling interoperability so customers can withdraw cash from any bank's ATM using their debit card. Connects over 2.5 lakh ATMs. RuPay is card network, UPI/IMPS are fund transfer systems. NFS handles ATM transaction routing and settlement.

Answer: Network

Network Layer (Layer 3) handles logical addressing (IP addresses), routing packets between networks, and path determination. Routers operate at this layer. Data Link (Layer 2) handles MAC addresses and local delivery; Transport (Layer 4) manages end-to-end connections and reliability.

Answer: INS Vikrant

INS Vikrant (IAC-1) is India's first indigenously designed and built aircraft carrier, commissioned in 2022. It incorporates Indian-developed systems including navigation, combat management, and communication. Represents a milestone in India's defense self-reliance (Atmanirbhar Bharat) and technological capability.

Answer: 2G

2G (specifically GPRS/EDGE enhancements) introduced packet-switched data enabling basic mobile internet, email, and MMS. 1G was analog voice only. 3G brought faster data for video calls and web browsing. 4G enabled HD video streaming and app ecosystems. Each generation built upon previous capabilities.

Answer: SSD

SSD (Solid State Drive) uses flash memory chips with no moving parts, offering faster boot times, file access, and durability compared to HDDs with spinning platters. SSDs are silent, consume less power, and are resistant to physical shock. Prices have decreased, making SSDs standard in modern devices.

Answer: CSRF

CSRF (Cross-Site Request Forgery) tricks authenticated users into executing unwanted actions on a web application where they're logged in. Attacker exploits trust between browser and site. Prevention: anti-CSRF tokens, SameSite cookies, checking referrer headers. Distinct from XSS which injects malicious scripts.

Answer: #

In Python, # denotes single-line comments. Multi-line comments use triple quotes (''' or """). Other languages: // and /* */ in C/Java/JavaScript, -- in SQL. Comments improve code readability and documentation but are ignored by compilers/interpreters during execution.

Answer: NISAR

NISAR (NASA-ISRO Synthetic Aperture Radar) is a joint Earth-observation satellite using dual-frequency radar to monitor ecosystems, ice masses, vegetation, and natural hazards. Scheduled for launch in 2024, it will provide unprecedented data for climate science and disaster management globally.
